如何在global.asax之外捕获应用程序错误？我想在global.asax

之外捕获未处理的异常

Answer 1

每个页面都来自System.Web.UI.Page。您可以覆盖每个单独页面的OnError方法，如下所示：

protected override void OnError(EventArgs e)
{
    // Capture the exception.
    var exception = HttpContext.Current.Server.GetLastError();

    // Create an error message.
    var errorInfo = 
       "<br/>URL: " + HttpContext.Current.Request.Url.ToString() +
       "<br/>Source: " + exception.Source + 
       "<br/>Message: " + exception.Message +
       "<br/>Stack trace: " + exception.StackTrace;

    // Write out the error message. You can do whatever you want with it.
    HttpContext.Current.Response.Write(errorInfo);

    // Clear the error that you handled from the cache so it's not read again.
    HttpContext.Current.Server.ClearError();

    // Perform the normal operations that would happen if you didn't override.
    base.OnError(e);
}
