Ejemplos

En el ejemplo siguiente se crea una instancia de una sealed clase, se comprueba la IsSealed propiedad y se muestra el resultado.

using namespace System;

// Declare MyTestClass as sealed.
ref class TestClass sealed{};

int main()
{
      TestClass^ testClassInstance = gcnew TestClass;
      
      // Get the type of testClassInstance.
      Type^ type = testClassInstance->GetType();
      
      // Get the IsSealed property of the myTestClassInstance.
      bool sealed = type->IsSealed;
      Console::WriteLine("{0} is sealed: {1}.", type->FullName, sealed);
}
// The example displays the following output:
//        TestClass is sealed: True.

using System;

 public class Example
 {
     // Declare InnerClass as sealed.
     sealed public class InnerClass
     {
     }

     public static void Main()
     {
          InnerClass inner = new InnerClass();
          // Get the type of InnerClass.
          Type innerType = inner.GetType();
          // Get the IsSealed property of  innerClass.
          bool isSealed = innerType.IsSealed;
          Console.WriteLine("{0} is sealed: {1}.", innerType.FullName, isSealed);
     }
}
// The example displays the following output:
//        Example+InnerClass is sealed: True.

module Example
// Declare InnerClass as sealed.
[<Sealed>]
type InnerClass() = class end

let inner = InnerClass()
// Get the type of InnerClass.
let innerType = inner.GetType()
// Get the IsSealed property of  innerClass.
let isSealed = innerType.IsSealed
printfn $"{innerType.FullName} is sealed: {isSealed}."
// The example displays the following output:
//        Example+InnerClass is sealed: True.

Public Class Example
    ' Declare InnerClass as sealed.
    Public NotInheritable Class InnerClass
    End Class
    
    Public Shared Sub Main()
         Dim inner As New InnerClass()
         ' Get the type of InnerClass.
         Dim innerType As Type = inner.GetType()
         ' Get the IsSealed property of InnerClass.
         Dim sealed As Boolean = innerType.IsSealed
         Console.WriteLine("{0} is sealed: {1}.", innerType.FullName, sealed)
    End Sub
End Class
' The example displays the following output:
'       Example+InnerClass is sealed: True.

Comentarios

Si el objeto actual Type representa un parámetro de tipo de un tipo genérico, esta propiedad siempre devuelve true.
