Question

我想在网络出现错误的情况下记录Exception。我在global.asax文件中进行了更改并生成了日志文件。代码在localhost上正常工作，但是当我在另一台服务器上上传global.asax文件的dll时，根据类似于localhost的网络凭据更改web配置。如果出现错误，该方法似乎不起作用，也不会创建文件来编写异常。请帮忙

 void Application_Error(object sender, EventArgs e)

这是因为您的应用程序在NETWORK SERVICE帐户下运行（默认情况下），并且没有权限在 ExceptionLogFiles 文件夹中写入。在文件夹属性中添加用户所有人并授予他该权限
