Typermittlung in VB.NET

[Michael Zimmerer]

Hi,

ich möchte prüfen, welchen Typs eine Variable ist, also z.B.:
<PRE>
Dim o as Object

o = new Windows.Forms.Button

If "Typ von o" = Windows.Forms.Button Then
...
ElseIf "Typ von o" = Windows.Forms.Form Then
...

Wie organisiere ich das am besten?

Gruß

Mit <pre>o.GetType()</pre>

Beispiel aus der Online - Hilfe:
<pre>
Beispiel
[C#, JScript] Das folgende Beispiel veranschaulicht, dass GetType den Laufzeittyp der aktuellen Instanz zurückgibt.
[C#]
using System;

public class MyBaseClass: Object {
}

public class MyDerivedClass: MyBaseClass {
}

public class Test {

public static void Main() {
MyBaseClass myBase = new MyBaseClass();
MyDerivedClass myDerived = new MyDerivedClass();
object o = myDerived;
MyBaseClass b = myDerived;

Console.WriteLine("mybase: Type is {0}", myBase.GetType());
Console.WriteLine("myDerived: Type is {0}", myDerived.GetType());
Console.WriteLine("object o = myDerived: Type is {0}", o.GetType());
Console.WriteLine("MyBaseClass b = myDerived: Type is {0}", b.GetType());
}
}

/*

This code produces the following output.

mybase: Type is MyBaseClass
myDerived: Type is MyDerivedClass
object o = myDerived: Type is MyDerivedClass
MyBaseClass b = myDerived: Type is MyDerivedClass

*/
