Unity C# GetSaveFileName()的实例详解【C#.Net教程】,GetSaveFileName,csharp,Unity,.net,应用

唉哟，此次凶猛咯，网上网罗了良久，终究被我找到汉化的保留对话框了，依据网上的一些先辈总结的内容，做了一些修正，

先放个效果图：

起首须要定义一个OpenFileName的类：

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]

public class OpenFileName
{
	public int structSize = 0;
	public IntPtr dlgOwner = IntPtr.Zero;
	public IntPtr instance = IntPtr.Zero;
	public String filter = null;
	public String customFilter = null;
	public int maxCustFilter = 0;
	public int filterIndex = 0;
	public String file = null;
	public int maxFile = 0;
	public String fileTitle = null;
	public int maxFileTitle = 0;
	public String initialDir = null;
	public String title = null;
	public int flags = 0;
	public short fileOffset = 0;
	public short fileExtension = 0;
	public String defExt = null;
	public IntPtr custData = IntPtr.Zero;
	public IntPtr hook = IntPtr.Zero;
	public String templateName = null;
	public IntPtr reservedPtr = IntPtr.Zero;
	public int reservedInt = 0;
	public int flagsEx = 0;
}

　　固然，也不是都用到了，只用到了一小部分，有性趣的童鞋能够个性化一下保留对话框，

然后是最主要的托付GetSaveName()要领：

public class DllUse
{
	[DllImport("Comdlg32.dll", SetLastError = true, ThrowOnUnmappableChar = true, CharSet = CharSet.Auto)]
	public static extern bool GetSaveFileName([In, Out] OpenFileName ofn);
}

　　挡挡挡，末了挪用一下即可：

public static void OpenDialog(Action<Stream> onSave)
    {
        OpenFileName ofn = new OpenFileName();
        ofn.structSize = Marshal.SizeOf(ofn);
    
        ofn.filter = "Excel (*.xls)\0*.xls\0\0";
        ofn.file = new string(new char[256]);
        ofn.maxFile = ofn.file.Length;
        ofn.fileTitle = new string(new char[64]);
        ofn.maxFileTitle = ofn.fileTitle.Length;
        ofn.initialDir = UnityEngine.Application.dataPath;//默许途径ofn.title = "保留文件";
        ofn.defExt = ".xls";//显示文件的范例ofn.flags = 0x00080000 | 0x00001000 | 0x00000800 | 0x00000200 | 0x00000008;if (DllTest.GetSaveFileName(ofn))
        {
            dosomething();string Savepath = Path.GetDirectoryName (ofn.file);
            Process.Start (Savepath);
        }
    }
