Type.IsInterface Properti

Definisi

Ruang nama:

System

Rakitan:

netstandard.dll, System.Runtime.dll

Sumber:

Type.cs

Mendapatkan nilai yang menunjukkan apakah Type itu antarmuka; yaitu, bukan kelas atau jenis nilai.

public:
 property bool IsInterface { bool get(); };

public bool IsInterface { get; }

member this.IsInterface : bool

Public ReadOnly Property IsInterface As Boolean

Nilai Properti

Boolean

true Type jika adalah antarmuka; jika tidak, false.

Contoh

Contoh berikut membuat antarmuka, memeriksa jenis antarmuka, dan menunjukkan apakah kelas memiliki IsInterface kumpulan properti.

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.

Keterangan

Membedakan ClassSemanticsMask deklarasi jenis sebagai kelas, antarmuka, atau jenis nilai.

Jika saat ini Type mewakili parameter jenis dalam definisi jenis generik atau metode generik, properti ini selalu mengembalikan false.

Properti ini bersifat hanya dapat dibaca.
