NullReferenceException on instantiated object?

阅读更多关于 NullReferenceException on instantiated object?

问题 This is a segment of code from an app I've inherited, a user got a Yellow screen of death: Object reference not set to an instance of an object on the line: bool l_Success ... Now I'm 95% sure the faulty argument is ref l_Monitor which is very weird considering the object is instantiated a few lines before. Anyone have a clue why it would happen? Note that I have seen the same issue pop up in other places in the code. IDMS.Monitor l_Monitor = new IDMS.Monitor(); l_Monitor.LogFile.Product_ID =

问题 Specifically, we are trying to upgrade our telerik controls to the latest version. Unfortunately, the old DLL's are so old that many of the control properties have changed vastly so we've decided to upgrade only the telerik control that is giving us problems (the RadEditor control). So the bin looks something like this: RadChart.Net2.dll RadEditor.Net2.dll (we want to get rid on only this one) RadGrid.Net2.dll RadInput.Net2.dll RadPanelbar.Net2.d RadSpell.NET2.dll RadTabStrip.Net2.d

Can the ASP.NET Yellow Screen of Death (YSOD) be generated on demand or captured?

阅读更多关于 Can the ASP.NET Yellow Screen of Death (YSOD) be generated on demand or captured?

问题 We'd like to just capture the YSOD output to use in an erorr reporting email, from a Global.asax error handler, for instance. Is there any way of leveraging the built-in ysod generator? 回答1: Yes there is a way that you can do this. In the Application_Error event in the global.asax file, get the last exception as an System.HttpUnhandledException. Your code will look like this: var lastException = Server.GetLastError() as HttpUnhandledException; string Ysod = lastException.GetHtmlErrorMessage()
