global.asax中的语法错误

Question

我的global.asax文件中有以下代码（在我的asp.net应用程序中）...

我在堆栈跟踪中有以下错误：

[NullReferenceException: Object reference not set to an instance of an object.]
Digita.Tustena.Global.Application_Start(Object sender, EventArgs e) +133

[HttpException (0x80004005): Object reference not set to an instance of an object.]

System.Web.HttpRuntime.EnsureFirstRequestInit(HttpContext context) +141

我的代码有什么问题？我赞美你的帮助...

查看Global.asax.cs文件中的Application_Start方法。那里有一个空引用。放一个try / catch并使用调试器来查看哪个对象为空。

如果使用dll部署pdb文件，堆栈跟踪也将包含行号。还要将调试信息设置为完整：项目属性 - ＆gt;构建 - ＆gt;高级 - ＆gt;调试信息（http://stackoverflow.com/a/3791997/57369）
