递归--遍历文件夹

因为有些脚本小子会注意到俺的网站，向网站文件夹里面搞一些乱七八糟的东西，或者传个木马上来，如果这样的话，俺会丢饭碗，会破产，所以俺用递归的方法写了个功能，来看看文件有没有给别人改动了，或者有不该存在的文件给传上来了，加密算法不写，因为怕人破解，只写遍历文件夹：

public static void SetAllSafeCode(string path)
    {
        path += "\\";
        //if there is no Directories, only files exists
        if (Directory.GetDirectories(path).Length == 0)
        {
            //check all files of this path
            foreach (string name in Directory.GetFiles(path))
            {
                //initialize  an safe string object
                SafeString ss = new SafeString();
                //set property of this object
                ss.FileName = name.Substring(path.Length);
                ss.FilePath = name;
                ss.Code = GetSafeCode(GetFileContent(name));
                //store this object into list
                ssList.Add(ss);
            }
            return;
        }
        else//if this path contains Directory
        {
            //check all directory of this path
            foreach (string name in Directory.GetDirectories(path))
            {
                SetAllSafeCode(name);//Recursion 递归
            }
            //check all files of this path
            foreach (string name in Directory.GetFiles(path))
            {
                SafeString ss = new SafeString();
                ss.FileName = name.Substring(path.Length);
                ss.FilePath = name;
                ss.Code = GetSafeCode(GetFileContent(name));
                ssList.Add(ss);
            }
        }
    }
