C#.NET 删除文件到回收站

导入命名空间   using System.Runtime.InteropServices;

 在类中定义方法属性：

  public class MessageBox{      /// <summary>    /// 删除文件到回收站    /// </summary>    /// <param name="path">删除文件的路径</param>    /// <returns></returns>     public static int DeleteFileToRecycleBin(string path)    {        _SHFILEOPSTRUCT pm = new _SHFILEOPSTRUCT();        pm.wFunc = FO_DELETE;        pm.pFrom = path + '/0';        pm.pTo = null;        pm.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION;        return SHFileOperation(pm);    }  

    private const int FO_DELETE = 0x3;    private const ushort FOF_NOCONFIRMATION = 0x10;    private const ushort FOF_ALLOWUNDO = 0x40;

       [DllImport("shell32.dll")]    private static extern int SHFileOperation([In, Out] _SHFILEOPSTRUCT str);}

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

public class _SHFILEOPSTRUCT{    public IntPtr hwnd;    public UInt32 wFunc;    public string pFrom;    public string pTo;    public UInt16 fFlags;    public Int32 fAnyOperationsAborted;    public IntPtr hNameMappings;    public string lpszProgressTitle;}
