JScript supports the use of structures, but not the declaration of new ones.
The following example demonstrates how to obtain a RuntimeTypeHandle from a type or from an object, and how to turn the handle back into a type.
Imports System
Imports System.Reflection
Public Class MyClass1
Private x As Integer = 0
Public Function MyMethod() As Integer
Return x
End Function 'MyMethod
End Class
Public Class MyClass2
Public Shared Sub Main()
Dim myClass1 As New MyClass1()
' Get the RuntimeTypeHandle from an object.
Dim myRTHFromObject As RuntimeTypeHandle = Type.GetTypeHandle(myClass1)
' Get the RuntimeTypeHandle from a type.
Dim myRTHFromType As RuntimeTypeHandle = GetType(MyClass1).TypeHandle
Console.WriteLine(vbLf & "myRTHFromObject.Value: {0}", _
myRTHFromObject.Value)
Console.WriteLine("myRTHFromObject.GetType(): {0}", _
myRTHFromObject.GetType())
Console.WriteLine("Get the type back from the handle...")
Console.WriteLine("Type.GetTypeFromHandle(myRTHFromObject): {0}", _
Type.GetTypeFromHandle(myRTHFromObject))
Console.WriteLine(vbLf & "myRTHFromObject.Equals(myRTHFromType): {0}", _
myRTHFromObject.Equals(myRTHFromType))
Console.WriteLine(vbLf & "myRTHFromType.Value: {0}", _
myRTHFromType.Value)
Console.WriteLine("myRTHFromType.GetType(): {0}", _
myRTHFromType.GetType())
Console.WriteLine("Get the type back from the handle...")
Console.WriteLine("Type.GetTypeFromHandle(myRTHFromType): {0}", _
Type.GetTypeFromHandle(myRTHFromType))
End Sub
End Class
