C#中如何删除一个文件夹下的所有文件

stirng winPath = "D:\\TargetDirectory”;         
stirng macPath = "/Users/用户名/Desktop/TargetDirectory”;

public static void ClearAllFiles (string path)
{
    try
    {
        if(Directory.Exists(path))
        {
            /** 删除文件夹下所有文件 */

            //方法一：
            //Directory.GetFiles(path).ToList().ForEach(
            //a => File.Delete(a));

            //方法二：
            //DirectoryInfo dirInfo = new DirectoryInfo(path);
            //dirInfo.GetFiles().ToList().ForEach(a => a.Delete());

            //方法三：
            //DirectoryInfo dirInfo = new DirectoryInfo(path);
            //dirInfo.GetFiles().ToList().ForEach(
            //a => File.Delete(a.FullName));

            /** 删除文件夹下所有文件夹 */

            //方法一：
            //Directory.GetDirectories(path).ToList().ForEach(
            //a => Directory.Delete(a, true));

            //方法二：
            //DirectoryInfo dirInfo = new DirectoryInfo(path);
            //dirInfo.GetDirectories().ToList().ForEach(a => a.Delete());

            //方法三：
            //DirectoryInfo dirInfo = new DirectoryInfo(path);
            //dirInfo.GetDirectories().ToList().ForEach(
            //a => Directory.Delete(a.FullName, true));

            /** 删除文件夹下所有文件与文件夹 */
            DirectoryInfo dirInfo = new DirectoryInfo(path);
            FileSystemInfo[] fileSysInfo = dirInfo.GetFileSystemInfos();
            foreach(FileSystemInfo fsi in fileSysInfo)
            {
                if(fsi is DirectoryInfo)
                {
                    Directory.Delete(fsi.FullName, true);
                }
                else
                {
                    File.Delete(fsi.FullName);
                }
            }
        }
        else
        {
            Directory.CreateDirectory(path);
        }
    }
    catch(Exception e)
    {
        Debug.Log("Exception: " + e.ToString());
    }   
}

注： FileInfo与DirectoryInfo都继承自抽象类FileSystemInfo。
