Exemplos

O exemplo a seguir cria uma interface, verifica o tipo de interface e indica se uma classe tem o IsInterface conjunto de propriedades.

using System;
// Declare an interface.
interface myIFace
{
}
class MyIsInterface
{
    public static void Main(string []args)
    {
        try
        {
            // Get the IsInterface attribute for myIFace.
            bool myBool1 = typeof(myIFace).IsInterface;
            //Display the IsInterface attribute for myIFace.
            Console.WriteLine("Is the specified type an interface? {0}.", myBool1);
            // Get the attribute IsInterface for MyIsInterface.
            bool myBool2 = typeof(MyIsInterface).IsInterface;
            //Display the IsInterface attribute for MyIsInterface.
            Console.WriteLine("Is the specified type an interface? {0}.", myBool2);
        }
        catch(Exception e)
        {
            Console.WriteLine("\nAn exception occurred: {0}.", e.Message);
        }
    }
}
/* The example produces the following output:

Is the specified type an interface? True.
Is the specified type an interface? False.
*/

// Declare an interface.
type myIFace = interface end

type MyIsInterface = class end

try
    // Get the IsInterface attribute for myIFace.
    let myBool1 = typeof<myIFace>.IsInterface
    //Display the IsInterface attribute for myIFace.
    printfn $"Is the specified type an interface? {myBool1}."
    // Get the attribute IsInterface for MyIsInterface.
    let myBool2 = typeof<MyIsInterface>.IsInterface
    //Display the IsInterface attribute for MyIsInterface.
    printfn $"Is the specified type an interface? {myBool2}."
with e ->
    printfn $"\nAn exception occurred: {e.Message}."
(* The example produces the following output:

Is the specified type an interface? True.
Is the specified type an interface? False.
*)

' Declare an interface.
Interface myIFace
End Interface

Class MyIsInterface
    Public Shared Sub Main()
        ' Get the IsInterface attribute for myIFace.
        Dim myBool1 As Boolean = GetType(myIFace).IsInterface
        Console.WriteLine("Is the specified type an interface? {0}.", myBool1)

        ' Determine whether Example is an interface.
        Dim myBool2 As Boolean = GetType(MyIsInterface).IsInterface
        Console.WriteLine("Is the specified type an interface? {0}.", myBool2)
        Console.ReadLine()

    End Sub
End Class
' The example displays the following output:
'       Is the specified type an interface? True.
'       Is the specified type an interface? False.

Comentários

O ClassSemanticsMask diferencia uma declaração de tipo como classe, interface ou tipo de valor.

Se a corrente Type representar um parâmetro de tipo na definição de um tipo genérico ou método genérico, essa propriedade sempre retornará false.

Esta propriedade é somente para leitura.
