[英]vb.net error using interface
I am getting this error 我收到了这个错误
"Error 19 Class 'LegacyRouteHandler' must implement 'Function GetHttpHandler(requestContext As RequestContext) As IHttpHandler' for interface 'System.Web.Routing.IRouteHandler'."
“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'。”
from this code: 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
I am clearly implementing GetHttpHandler
, any ideas why I am getting this error? 我正在清楚地实现
GetHttpHandler
,任何想法我为什么会收到此错误?
You need to add an Implements
clause after the function prototype. 您需要在函数原型之后添加一个
Implements
子句。
...) As IHttpHandler Implements IRouteHandler.GetHttpHandler

VB.NET doesn't automatically wire up functions to their interface definitions like C# does. VB.NET不会自动将函数连接到它们的接口定义,如C#。
