添加句柄错误 [英] Add a handle errors

问题描述

Public Shared Function CreateHyperLink(ByVal sURI As String, ByVal sDescription As String, ByVal ClickMethod As EventHandler(Of System.Windows.RoutedEventArgs)) As Hyperlink
     Dim hyper As New Hyperlink()
     hyper.Inlines.Add(sDescription)
     hyper.NavigateUri = New System.Uri(sURI)
     AddHandler hyper.Click, ClickMethod
     Return hyper
 End Function

上面的代码创建了一个超链接功能.
但是..

AddHandler hyper.Click，<<< ClickMethod>>>

出现"ClickMethod"错误.

错误:

类型"System.EventHandler(Of System.Windows.RoutedEventArgs)"的值不能转换为"System.Windows.RoutedEventHandler"

解决方案

看起来像您需要传递一个RoutedEventHandler，而不是您传递的内容.

Public Shared Function CreateHyperLink(ByVal sURI As String, ByVal sDescription As String, ByVal ClickMethod As EventHandler(Of System.Windows.RoutedEventArgs)) As Hyperlink
     Dim hyper As New Hyperlink()
     hyper.Inlines.Add(sDescription)
     hyper.NavigateUri = New System.Uri(sURI)
     AddHandler hyper.Click, ClickMethod
     Return hyper
 End Function

The above code creates a hyperlink function.
But..

AddHandler hyper.Click, <<< ClickMethod >>>

''ClickMethod'' is the error.

Error:

Value of type ''System.EventHandler (Of System.Windows.RoutedEventArgs)'' cannot be converted to ''System.Windows.RoutedEventHandler''

How Can Fix It?

解决方案

Looks like you need to pass in a RoutedEventHandler, not what you''re passing.
