使用PInvoke并调用MoveFileEx,传入null作为目的地….

这个链接有一些示例代码:

 [DllImport("kernel32.dll", CharSet = CharSet.Unicode)] public static extern bool MoveFileEx(string lpExistingFileName, string lpNewFileName, int dwFlags); public const int MOVEFILE_DELAY_UNTIL_REBOOT = 0x4; MoveFileEx(filename, null, MOVEFILE_DELAY_UNTIL_REBOOT);

问题是使用MOVEFILE_DELAY_UNTIL_REBOOT MoveFileEx将只删除空的文件夹。 参考文档。

我的解决方案如下:使用MOVEFILE_DELAY_UNTIL_REBOOT将目录中的每个文件都用MoveFileEx“删除”,然后以相同的方式“删除”目录。

 public class Cleanuper { private void PendingDeleteDirectory(string directoryPath) { foreach (string directory in Directory.GetDirectories(directoryPath, "*", SearchOption.TopDirectoryOnly)) { PendingDeleteDirectory(directory); } foreach (string file in Directory.GetFiles(directoryPath, "*", SearchOption.TopDirectoryOnly)) { NativeMethods.MoveFileEx(file, null, MoveFileFlags.DelayUntilReboot); } NativeMethods.MoveFileEx(directoryPath, null, MoveFileFlags.DelayUntilReboot); } } public static class NativeMethods { [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)] internal static extern bool MoveFileEx(string lpExistingFileName, string lpNewFileName, MoveFileFlags dwFlags); } [Flags] public enum MoveFileFlags { DelayUntilReboot = 0x00000004 }
