除了运用继续IConfigurationSectionHandler的要领定义处置惩罚自定义节点的类,还能够经由过程继续ConfigurationSection类完成一样效果。

起首说下.Net设置文件中一个潜规则

在设置节点时,关于想要举行存储的参数数据,能够采纳两种体式格局:一种是存储到节点的属性中,另一种是存储在节点的文本中。

由于一个节点能够有许多属性,然则只需一个innertext,而要在顺序中将这两种情势辨别开会带来复杂性。 为了防止这个题目,.net的设置文件只是用属性存储而不运用innertext.


接着,我们来写一个相符这个潜规则的自定义设置文件,轻易测试:

<mailServerGroup provider="www.baidu.com">
    <mailServers>
      <mailServer client="http://blog.csdn.net/lhc1105" address="13232@qq.com" userName="lhc" password="2343254"/>
      <mailServer client="http://blog345.csdn.net/lhc1105" address="132wdfgdsggtaewg32@qq.com" userName="dfshs水田如雅"  password="2334t243的萨芬234254"/>
      <mailServer client="http://blog436.csdn.net/lhc1105" address="132wdgadsfgdtaewg32@qq.com" userName="sdfhdfs水田如雅"  password="23ewrty2343的萨芬234254"/>
      <mailServer client="http://blo345734g.csdn.net/lhc1105" address="132wdgdfagdstaewg32@qq.com" userName="sdfher水田如雅"  password="23erwt43的萨芬234254"/>
    </mailServers>
  </mailServerGroup>

接着,我们来写响应的处置惩罚类,这里我们由内向外来写:

起首是最内层的mailServer:

 /// <summary>
    /// Class MailServerElement:用于映照mailServer节点,这里是现实存储数据的处所;
    /// </summary>
    /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 21:51:57</remarks>
    public sealed class MailServerElement : ConfigurationElement  //设置文件中的设置元素
    {

        /// <summary>
        /// Gets or sets the client.
        /// </summary>
        /// <value>The client.</value>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:05:40</remarks>
        [ConfigurationProperty("client", IsKey = true, IsRequired = true)]  //client是必需的key属性,有点儿主键的意义,比方,假如定义多个client雷同的节点,轮回读取的话就只读取到末了一个值
        public string Client
        {
            get
            {
                return this["client"] as string;
            }
            set
            {
                this["client"] = value;
            }

        }
        /// <summary>
        /// Gets or sets the address.
        /// </summary>
        /// <value>The address.</value>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:05:38</remarks>
        [ConfigurationProperty("address")]
        public string Address
        {
            get
            {
                return this["address"] as string;
            }
            set
            {
                this["address"] = value;
            }

        }
        /// <summary>
        /// Gets or sets the name of the user.
        /// </summary>
        /// <value>The name of the user.</value>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:05:35</remarks>
        [ConfigurationProperty("userName")]
        public string UserName
        {

            get
            {
                return this["userName"] as string;
            }
            set
            {
                this["userName"] = value;
            }

        }
        /// <summary>
        /// Gets or sets the password.
        /// </summary>
        /// <value>The password.</value>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:05:33</remarks>
        [ConfigurationProperty("password")]
        public string Password
        {

            get
            {
                return this["password"] as string;
            }
            set
            {
                this["password"] = value;
            }

        }



    }

接着是mailServers,它是一个mailServer的鸠合:

 /// <summary>
    /// Class MailServerCollection:映照mailServers节点,为一个鸠合类,别的还包含了许多对节点的操作要领,大部分继续自ConfigurationElementCollection
    /// </summary>
    /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 21:52:00</remarks>
    public sealed class MailServerCollection : ConfigurationElementCollection
    {
        /// <summary>
        /// 猎取 <see cref="T:System.Configuration.ConfigurationElementCollection" /> 的范例。
        /// </summary>
        /// <value>The type of the collection.</value>
        /// <returns>此鸠合的 <see cref="T:System.Configuration.ConfigurationElementCollectionType" />。</returns>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:05:08</remarks>
        public override ConfigurationElementCollectionType CollectionType
        {
            get
            {
                return ConfigurationElementCollectionType.BasicMap;
            }
         
        }


        /// <summary>
        /// 当在派生的类中重写时,建立一个新的 <see cref="T:System.Configuration.ConfigurationElement" />。
        /// </summary>

        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:05:03</remarks>
        protected override ConfigurationElement CreateNewElement()
        {
            return new MailServerElement();
        }

        /// <summary>
        /// 在派生类中重写时猎取指定设置元素的元素键。
        /// </summary>
        /// <param name="element">要为其返回键的 <see cref="T:System.Configuration.ConfigurationElement" />。</param>
        /// <returns>一个 <see cref="T:System.Object" />,用作指定 <see cref="T:System.Configuration.ConfigurationElement" /> 的键。</returns>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:04:51</remarks>
        protected override object GetElementKey(ConfigurationElement element)
        {
            return (element as MailServerElement).Client;
        }

        /// <summary>
        /// 猎取在派生的类中重写时用于标识设置文件中此元素鸠合的称号。
        /// </summary>
        /// <value>The name of the element.</value>
        /// <returns>鸠合的称号;否则为空字符串。默认值为空字符串。</returns>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 23:41:40</remarks>
        protected override string ElementName
        {
            get
            {
                return "mailServer";
            }
        }


        /// <summary>
        /// 猎取鸠合中的元素数。
        /// </summary>

        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:08:24</remarks>
        public new int Count
        {
            get { return base.Count; }
        }

        /// <summary>
        /// 猎取或设置此设置元素的属性、特征或子元素。
        /// </summary>
        /// <param name="index">The index.</param>
        /// <returns>MailServerElement.</returns>
        /// <remarks>Editor:v-liuhch</remarks>
        public MailServerElement this[int index]
        {

            get { return BaseGet(index) as MailServerElement; }
            set
            {
                if (BaseGet(index) != null)
                {
                    BaseRemoveAt(index);
                }
                BaseAdd(index, value);
            }

        }

        /// <summary>

        new public MailServerElement this[string Name]

        }

        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:24:16</remarks>
        public int IndexOf(MailServerElement element)
        {

            return BaseIndexOf(element);
        }

        /// <summary>
        /// Adds the specified element.
        /// </summary>
        /// <param name="element">The element.</param>

        public void Add(MailServerElement element)
        {
            BaseAdd(element);
        }

        /// <summary>
        /// Removes the specified element.
        /// </summary>
        /// <param name="element">The element.</param>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:27:01</remarks>
        public void Remove(MailServerElement element)
        {
            if (BaseIndexOf(element) > 0)
            {
                BaseRemove(element.Client);
            }
        }

        /// <summary>
        /// Removes at.
        /// </summary>
        /// <param name="index">The index.</param>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:33:29</remarks>
        public void RemoveAt(int index)
        {
            BaseRemoveAt(index);
        }

        /// <summary>
        /// Removes the specified client.
        /// </summary>
        /// <param name="client">The client.</param>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:34:04</remarks>
        public void Remove(string client)
        {
            BaseRemove(client);
        }

        /// <summary>
        /// Clears this instance.
        /// </summary>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:34:29</remarks>
        public void Clear()
        {
            BaseClear();
        }
    }

末了是最外层的group:

 /// <summary>
    /// Class MailServerSection 为进口:
    /// </summary>
    /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 21:41:02</remarks>
    public class MailServerSection : ConfigurationSection   //继续设置文件中节
    {
        /// <summary>
        /// Gets the provider.:映照mailServerGroup节点的provider
        /// </summary>
        /// <value>The provider.</value>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:05:59</remarks>
        [ConfigurationProperty("provider", IsKey = true)]
        public string provider { get { return this["provider"] as string; } }

        /// <summary>
        /// Gets or sets the mail servers.:映照新增加的节点mailServers节点;这个节点下还包含了若干个mailServer节点,因而它是一个鸠合类
        /// </summary>
        /// <value>The mail servers.</value>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 22:05:56</remarks>
        [ConfigurationProperty("mailServers", IsDefaultCollection = false)]
        public MailServerCollection MailServers
        {
            get
            {
                return this["mailServers"] as MailServerCollection;
            }
            set
            {
                this["mailServers"] = value;
            }

        }
    }

一样,关联处置惩罚类和节点:

 <section name="mailServerGroup" type="继续ConfigurationSection基类.MailServerSection,继续ConfigurationSection基类"/>   
  </configSections>

以后做个测试:

class Program
    {
        static void Main(string[] args)
        {
            Test();

        }

        /// <summary>
        /// Tests this instance.:读取节点值示例
        /// </summary>
        /// <remarks>Editor:v-liuhch CreateTime:2015/6/27 23:04:53</remarks>
        private static void Test() {

            MailServerSection mailSection = (MailServerSection)ConfigurationManager.GetSection("mailServerGroup");
            Console.WriteLine("MailServerSection 的provider属性值:"+mailSection.provider);
            foreach (MailServerElement config in mailSection.MailServers)
            {
                Console.WriteLine("----------------------------------");
                Console.WriteLine("client值为:"+config.Client);
                Console.WriteLine("address值为:"+config.Address);
                Console.WriteLine("username值为:"+config.UserName);
                Console.WriteLine("password值为:"+config.Password);
                Console.WriteLine("----------------------------------");
            }

            Console.ReadKey();

        }

    }

原本还想传张效果图,然则网速慢,算啦,喜好玩儿的童鞋本身run下效果。。。。。
