AddAllowedClass in GetEntity

I'm writing a program to list specific survey related data of Lines, Arcs, and Polylines.

i use the GetEntity function of the Editor.
I want to filter the types of objects that the user is allowed to pick.
I have seen code in C# using the AddAllowedClass of the PromptEntityOptions object. However i cannot seem to get it to work.

Here is my code thus far.....

Public Sub ListSurveyData()

Dim ed As Editor = Application.DocumentManager.MdiActiveDocument.Editor
Dim db As Database = HostApplicationServices.WorkingDatabase

Dim prEntOpt As PromptEntityOptions = New PromptEntityOptions("Select an Arc or Line: ")

''''Cant figure this part out. !!!!
prEntOpt.AddAllowedClass(Type.GetType(Line), True)
prEntOpt.AddAllowedClass(Type.GetType(Polyline), True)
prEntOpt.AddAllowedClass(Type.GetType(Arc), True)

prEntOpt.AllowNone = False

Dim prEntRes As PromptEntityResult = ed.GetEntity(prEntOpt)
If prEntRes.Status PromptStatus.OK Then Exit Sub

End Sub

Type.GetType() requires a string. Use the GetType operator instead of calling the GetType method of the System.Type class.

ie: use GetType(Line) instead of Type.GetType(Line)

If it still doesn't work, feel free to post again. :smileywink:
