ELMAH错误信令（ASP.NET）

Question

我已经启动并运行了以下代码。它捕获用于访问Intranet站点的用户名和浏览器。如何修改代码以便ELMAH将特定的StatusCode记录到SQLServer中的ELMAH_Error表？最终的目标是能够从日志中提取这些特定的日志条目，以确定哪些PC需要升级。

    Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
    ' Code that runs when a new session is started'

    Dim ExceptionMessage As New StringBuilder
    ExceptionMessage.Append(System.Security.Principal.WindowsIdentity.GetCurrent.Name + " accessed the site using " + Request.Browser.Browser + " " + Request.Browser.MajorVersion.toString + "." + Request.Browser.MinorVersion.tostring)
    Dim NewException As New NotSupportedException(ExceptionMessage.ToString)
    Elmah.ErrorSignal.FromCurrentContext().Raise(NewException)

End Sub
