Option Strict的后期绑定错误？

问题描述

大家好，


我有以下问题：我的程序运行正常，但是当我在表单顶部添加选项

strict时，以下子程序失败并显示错误选项

strict不允许后期绑定。我该怎么办？

Public Sub MyMnuHandler（ByVal sender As Object，ByVal e As System.EventArgs）


如果sender.checked = True那么发件人。 checked = False Else sender.checked = True


End Sub

Hi all,

I have the following problem: my program works fine, but when I add option
strict at the top of the form, the following sub fails with an error that option
strict does not allow late binding. What should I do?
Public Sub MyMnuHandler(ByVal sender As Object, ByVal e As System.EventArgs)

If sender.checked = True Then sender.checked = False Else sender.checked = True

End Sub

推荐答案

您需要将''sender''转换为正确的类型。


CType（发件人，MenuItem），Checked =非CType（发件人，MenuItem）。查看

You need to cast ''sender'' to the correct type.

CType(sender, MenuItem),Checked = Not CType(sender, MenuItem).Checked
