Question

程序化解决方案当然......

从上面:

using Microsoft.VisualBasic;

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

您需要深入研究非托管代码.这是我一直在使用的静态类:

public static class Recycle
{
    private const int FO_DELETE = 3;
    private const int FOF_ALLOWUNDO = 0x40;
    private const int FOF_NOCONFIRMATION = 0x0010;

    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto, Pack = 1)]
    public struct SHFILEOPSTRUCT
    {
        public IntPtr hwnd;
        [MarshalAs(UnmanagedType.U4)]
        public int wFunc;
        public string pFrom;
        public string pTo;
        public short fFlags;
        [MarshalAs(UnmanagedType.Bool)]
        public bool fAnyOperationsAborted;
        public IntPtr hNameMappings;
        public string lpszProgressTitle;
    }

    [DllImport("shell32.dll", CharSet = CharSet.Auto)]
    static extern int SHFileOperation(ref SHFILEOPSTRUCT FileOp);

    public static void DeleteFileOperation(string filePath)
    {
        SHFILEOPSTRUCT fileop = new SHFILEOPSTRUCT();
        fileop.wFunc = FO_DELETE;
        fileop.pFrom = filePath + '\0' + '\0';
        fileop.fFlags = FOF_ALLOWUNDO | FOF_NOCONFIRMATION;

        SHFileOperation(ref fileop);
    }
}

• Tsk tsk @ Jeff在C#代码中使用"Microsoft.VisualBasic".
• Tsk tsk @ MS将所有好东西放在VisualBasic命名空间中.

我发现的最好方法是使用VB函数FileSystem.DeleteFile.

Microsoft.VisualBasic.FileIO.FileSystem.DeleteFile(file.FullName,
    Microsoft.VisualBasic.FileIO.UIOption.OnlyErrorDialogs,
    Microsoft.VisualBasic.FileIO.RecycleOption.SendToRecycleBin);

它需要添加Microsoft.VisualBasic作为参考,但这是.NET框架的一部分,因此不是额外的依赖.

替代解决方案需要P/Invoke到SHFileOperation,以及定义所有各种结构/常量.Microsoft.VisualBasic相比之下,包括更整洁.
