Type.IsInterface 屬性
定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得值，指出 Type 是否為介面；也就是說，不是類別或實值類型。
public:
property bool IsInterface { bool get(); };public bool IsInterface { get; }member this.IsInterface : boolPublic ReadOnly Property IsInterface As Boolean屬性值
如果 true 是介面，則為 Type，否則為 false。
實作
範例
下列範例會建立介面、檢查介面型別，並指出類別是否已 IsInterface 設定屬性。
using namespace System;
// Declare an interface.
interface class myIFace{};
public ref class MyIsInterface{};
void main()
{
try
{
// Get the IsInterface attribute for myIFace.
bool myBool1 = myIFace::typeid->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 = MyIsInterface::typeid->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.
*/
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.
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.
備註
會將型別宣告區 ClassSemanticsMask 分為類別、介面或實值型別。
如果目前 Type 表示泛型型別或泛型方法定義中的類型參數，則這個屬性一律會傳回 false 。
這是唯讀的屬性。
