I need to store a list of modules.functions() in an array and then
loop thru the array and call the functions. I have not been able to
get any code to work.
Here's what I need to do:
dim myArr(3) as string
myArr(0) = "MyModA.Func1()"
myArr(2) = "MyModA.Func2()"
myArr(3) = "MyModB.Func1()"
myArr(4) = "MyModB.Func2()"
dim iCnt, iRet as integer
FOR iCnt = 0 TO myArr.Length -1
iRet = myArr(0)
NEXT iCnt
I know why this doesn't work, but I
don't know how to figure out how to approach it.
Any help will be much appreciated.
Thanks,
Marc Miller
Below is a sample implementation using delegates. You will need to translate
it to use your objects and methods. The delegate scheme should be more performant
as it does not need to use reflection, but rather has direct pointers to
the method calls. Also, notice that the methods added to the list are strongly
typed rather than being latebound as strings in your example. Note that if
you need to pass parameters to the methods, things start to get a bit more
tricky. This should give you enough to get started though.
Public Class MyApplication
<STAThread()_
Public Shared Sub Main()
Dim tester As New MyDelegates
Dim methodList As New List(Of SampleDelegate)
methodList.Add(AddressOf tester.Test1)
methodList.Add(AddressOf tester.Test2)
For Each method As [Delegate] In methodList
method.Method.Invoke(tester, Nothing)
Next
Console.ReadLine()
End Sub
End Class
Public Class MyDelegates
Public Sub Test1()
Console.WriteLine("Testing 1")
End Sub
Public Sub Test2()
Console.WriteLine("Testing 2")
End Sub
End Class
Public Delegate Sub SampleDelegate()
