应用Razor引擎生成静态页（ASP.NET MVC）实例详解【C#.Net教程】,Razor，静态页，ASP.NET

最近在研讨ASP.NET MVC生成静态页，那末本日也算个进修笔记吧！

完成道理及步骤：

1.经由过程ViewEngines.Engines.FindView查找到对应的视图，如果是部份视图，则用：ViewEngines.Engines.FindPartialView；

2.设置上下文对象里的Model；

3.挪用视图的Render()要领，将衬着效果保存到物理静态文件；

using System; 
using System.IO; 
using System.Text; 
using System.Web.Mvc; 
 
namespace Whir.Foundation.UI 
{ 
  /// <summary> 
  ///   形貌：静态页面生成协助类 
  /// </summary> 
  public class StaticPageHelper 
  { 
    /// <summary> 
    ///   依据View视图生成静态页面 
    /// </summary> 
    /// <param name="htmlPath">寄存静态页面地点绝对途径</param> 
    /// <param name="context">ControllerContext</param> 
    /// <param name="viewPath">视图称号</param> 
    /// <param name="masterName">模板视图称号</param> 
    /// <param name="model">参数实体模子</param> 
    /// <param name="html">返回信息</param> 
    /// <param name="isPartial">是不是散布视图</param> 
    /// <returns>生成胜利返回true,失利false</returns> 
    public static AjaxResult GenerateStaticPage(string viewPath, 
                          string htmlPath, 
                          ControllerContext context, object model = null, bool isPartial = false, 
                          string masterName = "") 
    { 
      var ajaxResult = new AjaxResult(); 
      try 
      { 
        //建立寄存静态页面目次               
        if (!Directory.Exists(Path.GetDirectoryName(htmlPath))) 
        { 
          Directory.CreateDirectory(Path.GetDirectoryName(htmlPath)); 
        } 
        //删除已有的静态页面 
        if (File.Exists(htmlPath)) 
        { 
          File.Delete(htmlPath); 
        } 
        ViewEngineResult result = null; 
        if (isPartial) 
        { 
          result = ViewEngines.Engines.FindPartialView(context, viewPath); 
        } 
        else 
        { 
          result = ViewEngines.Engines.FindView(context, viewPath, masterName); 
        } 
 
        if (model != null) 
        { 
          context.Controller.ViewData.Model = model; 
        } 
 
        /* 
         * 设置暂时数据字典作为静态化标识 
         * 能够在视图上运用TempData["IsStatic"]来掌握某些元素显现。 
         */ 
        if (!context.Controller.TempData.ContainsKey("IsStatic")) 
        { 
          context.Controller.TempData.Add("IsStatic", true); 
        } 
 
        if (result.View != null) 
        { 
          using (var sw = new StringWriter()) 
          { 
            var viewContext = new ViewContext(context, 
                             result.View, 
                             context.Controller.ViewData, 
                             context.Controller.TempData, sw); 
 
            result.View.Render(viewContext, sw); 
 
            string body = sw.ToString(); 
            File.WriteAllText(htmlPath, body, Encoding.UTF8); 
            ajaxResult.IsSucess = true; 
            ajaxResult.Body = "寄存途径：" + htmlPath; 
          } 
        } 
        else 
        { 
          ajaxResult.IsSucess = false; 
          ajaxResult.Body = "生成静态页面失利！未找到视图！"; 
        } 
      } 
      catch (IOException ex) 
      { 
        ajaxResult.IsSucess = false; 
        ajaxResult.Body = ex.Message; 
      } 
      catch (Exception ex) 
      { 
        ajaxResult.IsSucess = false; 
        ajaxResult.Body = ex.Message; 
      } 
      return ajaxResult; 
    } 
  } 
}

AjaxResult 是本身封装的一个类，您也能够用本身封装的类替代。

  public class AjaxResult
  {
    public bool IsSucess { get; set; }
    public string Body { get; set; }
  }
