是的，这是正确的方法。如果你想给自己一个“干净”（或者，我更喜欢称之为“空”函数），你可以创建一个扩展方法。

public static void Empty(this System.IO.DirectoryInfo directory)
{
    foreach(System.IO.FileInfo file in directory.GetFiles()) file.Delete();
    foreach(System.IO.DirectoryInfo subDirectory in directory.GetDirectories()) subDirectory.Delete(true);
}

然后，这将允许您执行以下操作：。。

System.IO.DirectoryInfo directory = new System.IO.DirectoryInfo(@"C:\...");

directory.Empty();

string directoryPath = "C:\Temp";
Directory.GetFiles(directoryPath).ToList().ForEach(File.Delete);
Directory.GetDirectories(directoryPath).ToList().ForEach(Directory.Delete);

这是我看完所有帖子后使用的工具。确实如此

删除所有可以删除的内容如果某些文件保留在文件夹中，则返回false

它处理的是

只读文件删除延迟锁定的文件

它不使用Directory.Delete，因为该进程因异常而中止。

    /// <summary>
    /// Attempt to empty the folder. Return false if it fails (locked files...).
    /// </summary>
    /// <param name="pathName"></param>
    /// <returns>true on success</returns>
    public static bool EmptyFolder(string pathName)
    {
        bool errors = false;
        DirectoryInfo dir = new DirectoryInfo(pathName);

        foreach (FileInfo fi in dir.EnumerateFiles())
        {
            try
            {
                fi.IsReadOnly = false;
                fi.Delete();

                //Wait for the item to disapear (avoid 'dir not empty' error).
                while (fi.Exists)
                {
                    System.Threading.Thread.Sleep(10);
                    fi.Refresh();
                }
            }
            catch (IOException e)
            {
                Debug.WriteLine(e.Message);
                errors = true;
            }
        }

        foreach (DirectoryInfo di in dir.EnumerateDirectories())
        {
            try
            {
                EmptyFolder(di.FullName);
                di.Delete();

                //Wait for the item to disapear (avoid 'dir not empty' error).
                while (di.Exists)
                {
                    System.Threading.Thread.Sleep(10);
                    di.Refresh();
                }
            }
            catch (IOException e)
            {
                Debug.WriteLine(e.Message);
                errors = true;
            }
        }

        return !errors;
    }

using System.IO;

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");

foreach (string filePath in filePaths)

File.Delete(filePath);

以下代码将递归清除文件夹：

private void clearFolder(string FolderName)
{
    DirectoryInfo dir = new DirectoryInfo(FolderName);

    foreach(FileInfo fi in dir.GetFiles())
    {
        fi.Delete();
    }

    foreach (DirectoryInfo di in dir.GetDirectories())
    {
        clearFolder(di.FullName);
        di.Delete();
    }
}
