验证设置路径字符串 路径字符串 路径无效 static public void ValidatePath(string path) { if (path == null) throw new ArgumentException (路径不能为空); if (path.Length == 0) throw new ArgumentException(路径长度必须大于0); if (path ! = ) throw new ArgumentException(路径必须启动字符); if (path.Length == 1) return; if (path == ) throw new ArgumentException = null) throw new ArgumentException(string.Format(无效的路径字符串 {0} 引起的 {1}, path, reason)); }2.查看服务器的路径：
