解决 Global.asax的Application_Error中记录"文件不存在"的问题

protected void Application_Error(object sender, EventArgs e)
{
// 在出现未处理的错误时运行的代码
Exception ex = Server.GetLastError().GetBaseException();
if (ex.GetType().Name.Equals("HttpException"))
{
HttpException httpEx = (HttpException)ex;
int httpCode = httpEx.GetHttpCode();
if (httpCode == 404) return;
}
Logger.Error("程序发生未捕获的异常\t\t\t" + HttpContext.Current.Error.Message + "\r\n" + ex.StackTrace, HttpContext.Current.Error);

}
