推荐答案

<customerrors>
       mode="RemoteOnly" 
       defaultRedirect="~/errors/GeneralError.aspx" /></customerrors>

您可以通过在Global.asax文件中添加以下代码来实现相同的目的.
这很简单，很容易解释

The same you can achieve by adding below code in Global.asax file.
It is simple and self explanatory

Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
        '' Code that runs when an unhandled error occurs
        Dim ctx As HttpContext = HttpContext.Current
        Dim exception As Exception = ctx.Server.GetLastError
        Dim errInfo As String = "<br>Error In : " & ctx.Request.Url.ToString() & _
        "<br>Source:" & exception.Source & _
        "<br>Message: " & exception.Message
        '"<br>Stack Trace: " & exception.StackTrace 
        ctx.Response.Write(errInfo)
        'To let the page finish running we clear the error
        ctx.Server.ClearError()
        Session("value") = errInfo
'GenericError is the page where i am redirecting user with message
        System.Web.HttpContext.Current.Response.Redirect("~/GenericError.aspx")
    End Sub</br></br></br></br>

我通常更喜欢第二种选择，因为您可以在需要时获得错误的完整详细信息.

快乐编码

代码已格式化

I normally prefer 2nd option because you get the complete details of errors when required.
