.NET Framework (current version)
Gets a value indicating whether the Type is an interface; that is, not a class or a value type.

Implements
_Type.IsInterfaceThe ClassSemanticsMask distinguishes a type declaration as class, interface or value type.
If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.
This property is read-only.
The following example creates an interface, checks for the interface type, and indicates whether a class has the IsInterface property set.
' Declare an interface. Interface IInterface End Interface Class Example : Implements IInterface Public Shared Sub Main() ' Determine whether IInterface is an interface. Dim isInterface1 As Boolean = GetType(IInterface).IsInterface Console.WriteLine("Is IInterface an interface? {0}", isInterface1) ' Determine whether Example is an interface. Dim isInterface2 As Boolean = GetType(Example).IsInterface Console.WriteLine("Is Example an interface? {0}", isInterface2) End Sub End Class ' The example displays the following output: ' Is IInterface an interface? True ' Is Example an interface? False
