方法1：直接删除法

 

DirectoryInfo di = new DirectoryInfo(string Path);di.Delete(true);

 

注：path是你要删除的非空目录；
     true：你要删除里面所有的文件，包括文件夹和子文件夹

 

方法2：层级删除法

 

/// <summary>/// 删除非空文件夹/// </summary>/// <param name="path">要删除的文件夹目录</param>void DeleteDirectory(string path){DirectoryInfo dir = new DirectoryInfo(path); if (dir.Exists){DirectoryInfo[] childs = dir.GetDirectories();foreach (DirectoryInfo child in childs){child.Delete(true);}dir.Delete(true);}}

 

方法3：
递归方法(删除目录和文件)

private staticv oid DeleteDirectory(File tmpFile) {if (!tmpFile.exists()) {System.out.println("file is not exist!");return;}if (tmpFile.isDirectory()) {File[] fileList = tmpFile.listFiles();for (int i =0; i < fileList.length; i++) {if (fileList[i].isDirectory()) {DeleteDirectorys(fileList[i]);s}　　}}
}

方法4：递归删除法（删除目录和文件）

 

static void DeleteDirectory(string dir)
{
if (Directory.GetDirectories(dir).Length == 0 && Directory.GetFiles(dir).Length == 0)
{
Directory.Delete(dir);
return;
}
foreach (string var in Directory.GetDirectories(dir))
{
DeleteDirectory(var);
}
foreach (string var in Directory.GetFiles(dir))
{
File.Delete(var);
}
Directory.Delete(dir);
}
