在网络上记录异常错误

Question

我想记录异常以防网络出错。我对 global.asax 文件进行了更改并在其中生成了日志文件。该代码在 localhost 上运行良好，但是当我在另一台服务器上上传 global.asax 文件的 dll 并根据类似于 localhost 的网络凭据更改 Web 配置时。如果出现错误，该方法似乎不起作用，也没有创建文件来写入异常。请帮忙

 void Application_Error(object sender, EventArgs e)
        {
            // Code that runs when an unhandled error occurs
            try

这是因为您的应用程序在 NETWORK SERVICE 帐户下运行（默认情况下）并且没有写入 ExceptionLogFiles 文件夹的权限。在文件夹属性中添加用户 Everyone 并授予他该权限
