使用界面时出现vb.net错误

Question

我收到了这个错误

"错误19类'LegacyRouteHandler'必须实现'Function GetHttpHandler(requestContext As RequestContext)作为IHttpHandler'用于接口'System.Web.Routing.IRouteHandler'."

从这段代码:

Public Class LegacyRouteHandler
    Implements IRouteHandler
    Public Function GetHttpHandler(requestContext As RequestContext) As IHttpHandler
        Return New LegacyHandler(requestContext)
    End Function
End Class

我正在明确实施GetHttpHandler,为什么我收到此错误的任何想法？

Answer 1

您需要Implements在函数原型之后添加一个子句.

...) As IHttpHandler Implements IRouteHandler.GetHttpHandler
'                    ^

VB.NET不会自动将函数连接到它们的接口定义,如C#.
