Getting object type without creating object

[Raghu]

In C#, the typeof keyword can be used to get a type of the class. This does
not require object to be created first. However O am not sure how do the
same thing in vb. I don't want to create the object just to get its type. I
would appreciate if any one can can show me how to do this in vb.net.

Thanks.

Raghu,
Use the GetType operator, instead of the GetType method.

Dim t As Type = GetType(Integer)

If you want to check an object variable for a specific type you can use the
TypeOf Is operator.

Dim o As Object
If TypeOf o Is Integer Then
' we have an Integer here!
End If

Hope this helps
Jay

I did not make my self clear. I can write following code in csharp:

public class MyAgent {
...
}

Type t = typeof(MyAgent);

When I write following vb.net code, it fails to compile:

Public Class MyAgent
....
End Class

Dim t as Type

t = Type.GetType(MyAgent)

However I can write following code, but it does not catch compile time error
if class name is changed:

t = Type.GetType("MyAgent")

Any ideas?

Thanks.

Use 't = GetType(MyAgent)'.

Raghu,
I gave you an example, Herfried gave you the documentation.

Use the GetType operator, not the Type.GetType method!

Dim t as Type

t = GetType(MyAgent)

Hope this helps
