C#-调试记Log文件

using System.IO;

//捕获异常写入Log
catch (Exception ex)
 {

    string msg = ex.Message + ex.StackTrace;
     string path = @"E:\log.txt";
     write(path, msg);

}

        public void Write(string str_path,string str_msg)
        {
            //FileMode.Append为不覆盖文件效果.create为覆盖
            FileStream fs = new FileStream(str_path, FileMode.Append);
            string str_time = DateTime.Now.ToString();
            //获得字节数组
            byte[] data = System.Text.Encoding.Default.GetBytes("\r\n"+ str_time +"\t"+ str_msg);
            //开始写入
            fs.Write(data, , data.Length);

            //清空缓冲区、关闭流
            fs.Flush();
            fs.Close();
        }
