推荐答案

您可以使用循环:

You can use a loop:

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");
foreach (string filePath in filePaths)
   {
   File.Delete(filePath);
   }

您可以将Array.ForEach与匿名方法一起使用:

You can use Array.ForEach with an anonymous method:

Array.ForEach(Directory.GetFiles(@"c:\MyDir\"), delegate(string path) { File.Delete(path); });

或者您可以使用

Or you could use

Directory.Delete(path, true);
Directory.CreateDirectory(path);

删除文件夹及其内容和所有子目录，然后重新创建文件夹.

to remove the folder, it''s contents, and all subdirectories, then re-create the folder.

public void DeleteAllTempFiles()

{

foreach (var f in System.IO.Directory.GetFiles(Server.MapPath("~/temp")))

System.IO.File.Delete(f);

}

首先要做这些事情，您应该具有正确的安全性并对该文件夹具有读/写权限.

然后，您可以尝试这段代码:

First of all to do such things you should have the right security and read/write permissions on that folder.

Then you can try this piece of code :

DirectoryInfo objDir = new DirectoryInfo(sPath);

 //Check whether path exists
 if (objDir.Exists)
 {
     FileInfo[] objFile = objDir.GetFiles();
     for (int iIndex = 0; iIndex < objFile.Length; iIndex++)
     {
            File.Delete(objFile[0].DirectoryName + "\\" + objFile[0].Name);
     }
 }
