推荐答案

您知道代码的详细信息以及要记录的内容. Server.MapPath("/App_Data")将为您提供一个文件系统路径，您可以将其写入此位置. System.IO.File.WriteAllText是编写您创建的日志文本的最简单方法.

You know the details of your code, and what you want to log. Server.MapPath("/App_Data") will give you a file system path to one place you could write this. System.IO.File.WriteAllText is the easiest way to write the text of the log you create.

您是否正在使用第3部分应用程序进行转换.如果是，那么您别无选择地记录错误.

如果应用程序是由您编写的，那么很容易记录您的错误.

在将数据传输到另一个数据库的代码中，通过插入语句，您需要捕获catch异常.发生任何错误，您需要更新日志文本文件.

Are you using a 3rd paty application to convert. If yes, then you have no choice to log error.

If the application is written by you, the it is pretty straight forward to log your error.

In the code where you are transferring data to another database, by insert statement, you need to trap the catch exception. Any error, you need to update the log text file.

try{
  //your code - inserting/updating data or bulk insert/update
}
catch(SqlException ex){
  //create error log
  //take the detail exception string from ex and generate a string with other details you want and send it to a text file.
}

希望有帮助.
