Type.IsInterface Property
Gets a value indicating whether the Type is an interface; that is, not a class or a value type.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
The 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.
Imports System Imports Microsoft.VisualBasic ' Declare an interface. Interface myIFace End Interface 'myIFace Class MyIsInterface Public Shared Sub Main() Try ' Get the IsInterface attribute for myIFace. Dim myBool1 As Boolean = GetType(myIFace).IsInterface ' Display the IsInterface attribute for myIFace. Console.WriteLine("Is the specified type an interface? {0}.", myBool1.ToString) ' Get the IsInterface attribute for MyIsInterface. Dim myBool2 As Boolean = GetType(MyIsInterface).IsInterface ' Display the IsInterface attribute for MyIsInterface. Console.WriteLine("Is the specified type an interface? {0}.", myBool2.ToString) Catch e As Exception Console.WriteLine(ControlChars.Cr + "An exception occurred: {0}", e.Message.ToString) End Try End Sub 'Main End Class 'MyIsInterface
