网络上的日志异常错误

我想在网络出现错误时记录异常。我对global.asax文件进行了更改，并在其中生成了日志文件。该代码在本地主机上正常工作，但是当我将另一台服务器上的global.asax文件的dll上传并根据类似于本地主机的网络凭证更改Web配置时。如果出现错误，该方法似乎不起作用，也不会创建写入该异常的文件。请帮助网络上的日志异常错误

可能是其权限问题，iis应用程序池用户是否有权在您指定的路径上写入？尝试给该文件夹上的所有人写入权限， –

请检查您是否具有读取和写入该服务器的权限......可能只有权限问题。 – pedram

这是因为应用程序在网络服务帐户下运行（默认），并没有权限在ExceptionLogFiles文件夹来写。添加用户所有人在文件夹属性中授予他该权限

我做了我手动测试的文件创建并拥有所有权限。是global.asax.dll唯一的DLL在错误的情况下生成的？ –

但你说这个日志文件没有创建。那么究竟是哪里出了问题？ – 2015-09-28 11:29:33

您是否尝试过重新启动应用程序池。如果文件正在创建，那么有什么问题？请详细说明您的实际查询。 – pedram
