The Directory.Deletemethod has a recursive boolean parameter, it should do what you need

Err, what about just calling Directory.Delete(path, true);?
呃，只是打电话Directory.Delete(path, true);怎么样？

Try:
尝试：
System.IO.Directory.Delete(path,true)
This will recursively delete all files and folders underneath "path" assuming you have the permissions to do so.
假设您有权限这样做，这将递归删除“路径”下的所有文件和文件夹。

You should use:
你应该使用：
dir.Delete(true);
for recursively deleting the contents of that folder too. See MSDN DirectoryInfo.Delete() overloads.
也用于递归删除该文件夹的内容。请参阅 MSDN DirectoryInfo.Delete() 重载。

public void Empty(System.IO.DirectoryInfo directory)
{
try
{
logger.DebugFormat("Empty directory {0}", directory.FullName);
foreach (System.IO.FileInfo file in directory.GetFiles()) file.Delete();
foreach (System.IO.DirectoryInfo subDirectory in directory.GetDirectories()) subDirectory.Delete(true);
}
catch (Exception ex)
{
ex.Data.Add("directory", Convert.ToString(directory.FullName, CultureInfo.InvariantCulture));
throw new Exception(string.Format(CultureInfo.InvariantCulture,"Method:{0}", ex.TargetSite), ex);
}
}

Try this.
尝试这个。
namespace EraseJunkFiles
{
class Program
{
static void Main(string[] args)
{
DirectoryInfo yourRootDir = new DirectoryInfo(@"C:\somedirectory\");
foreach (DirectoryInfo dir in yourRootDir.GetDirectories())
DeleteDirectory(dir.FullName, true);
}
public static void DeleteDirectory(string directoryName, bool checkDirectiryExist)
{
if (Directory.Exists(directoryName))
Directory.Delete(directoryName, true);
else if (checkDirectiryExist)
throw new SystemException("Directory you want to delete is not exist");
}
}
}

Try This:
尝试这个：
foreach (string files in Directory.GetFiles(SourcePath))
{
FileInfo fileInfo = new FileInfo(files);
fileInfo.Delete(); //delete the files first.
}
Directory.Delete(SourcePath);// delete the directory as it is empty now.
