在运行时调用方法 [英] Calling a method at runtime

问题描述

我想基于字符串动态调用方法


例如


当s =" A"然后方法A将被调用。我不是不想使用一堆如果的话。声明。


类似于：


someMethod = AddressOf s's = A


someMethod（SomeSortOfString）

Sub A（ByRef SomeString As String）

...

End Sub


Sub B（ByRef SomeString As String）

...

End Sub


这可能吗？

I want to call a method dynamically based on a string

For example

When s = "A" Then method A would get called. I don''t wan''t to use a
bunch of "If" statements.

Something like:

someMethod = AddressOf s ''s = A

someMethod(SomeSortOfString)
Sub A(ByRef SomeString As String)
...
End Sub

Sub B(ByRef SomeString As String)
...
End Sub

Is this possible?

当然


案例选择myMethode

案例A

A

案例B

B

结束选择


Sub A（ByRef SomeString As String）

...

End Sub


Sub B（ByRef SomeString As String）

....

End Sub


我希望这有帮助吗？

Rico

Of Course

Case select myMethode
Case "A"
A
Case "B"
B
End Select

Sub A(ByRef SomeString As String)
...
End Sub

Sub B(ByRef SomeString As String)
....
End Sub

I hope this helps?

假设方法的签名是相同的，你可以使用

委托这样做...


Dim someMethodDelegate（SomeSortOfString As String）作为[代表]


someMethodDelegate = AddressOf A

someMethodDelegate（SomeSortOfString）

....


Sub A（ SomeString As String）

....

End Sub


Sub B（SomeString As String）

....

End Sub

news：40 **************** @ news.verizon.net:

Assuming that the signatures of the methods are the same, you can use a
delegate to do so...

Dim someMethodDelegate(SomeSortOfString As String) As [Delegate]

someMethodDelegate = AddressOf A
someMethodDelegate(SomeSortOfString)

....

Sub A(SomeString As String)
....
End Sub

Sub B(SomeString As String)
....
End Sub
