我发现这个，不知道它是否。作品，但它是值得一试。

I found this, don't know if it works, but it's worth a shot.

using Microsoft.VisualBasic;

string path = @"c:\myfile.txt";
FileIO.FileSystem.DeleteDirectory(path, FileIO.UIOption.OnlyErrorDialogs, RecycleOption.SendToRecycleBin);

编辑：从Nifle明智的话：
只记得添加到Microsoft.VisualBasic程序参考.DLL

Wise words from Nifle: Just remember to add a reference to Microsoft.VisualBasic.dll
