往往要在调试的过程中记录一些信息，用一个txt存好，可以慢慢查看，这里有一个简单的类可以用（功能单一，用c#写的）：

class MessageRecord    {        public static void RecordMessage(string path, string msg)        {            StreamWriter writer = new StreamWriter(path, true);            writer.WriteLine(string.Format("{0}  {1}" ,                DateTime.Now  , msg));            writer.Close();        }        public static void RecordMessage(string path, bool append, string msg)        {            StreamWriter writer = new StreamWriter(path, append);            writer.WriteLine(string.Format("{0}  {1}",                DateTime.Now, msg));            writer.Close();        }    }//end class
