Have you ever wondered how to do that. This can be useful if you build a custom control and want user to tell you what function to call, for some reason. Code shown bellow.
Public Shared Function CallFunctionByReflection(ByVal className As String, ByVal functionName As String, ByVal arguments As Object()) Dim theType As Type = Nothing Dim theObj As [Object] = Nothing Dim theMethodInfo As MethodInfo = Nothing theType = System.Type.GetType(className) theObj = Activator.CreateInstance(theType) Try theMethodInfo = theType.GetMethod(functionName) If arguments IsNot Nothing Then Return theMethodInfo.Invoke(theObj, arguments) Else Return theMethodInfo.Invoke(theObj, Nothing) End If Catch Ex As Exception Throw Ex Return Nothing Finally theType = Nothing theObj = Nothing theMethodInfo = Nothing End Try End Function
