Question

我正在尝试使用简单的LINQ to Objects查询。

当我尝试运行我的应用程序时，我收到消息：

System.InvalidOperationException was unhandled
  Message="An error occurred creating the form. See Exception.InnerException for details.  The error is: Method not found: 'Void sharatTashlumimWS.paymentDetailsManager.set_ReleaseDate(System.DateTime)'."

如果我将此代码放在ASP应用程序中，它运行良好。

我的linq声明是：

Dim query = From m In movies Select m

Answer 1

查看InnerException

InnerException: System.MissingMethodException
       Message="Method not found: 'Void sharatTashlumimWS.paymentDetailsManager.set_ReleaseDate(System.DateTime)'."
       Source="WindowsApplication1"
       StackTrace:
            at WindowsApplication1.Form1..ctor()
       InnerException:

Answer 2

根据给出的例外情况，它看起来似乎永远不会出现在您的查询中 - 设置Form1时出现问题，可能是在制作电影表时。

linq to object - 找不到方法
