Type.IsSealed Property
.NET Framework 4.5
Gets a value indicating whether the Type is declared sealed.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
If the current Type represents a type parameter of a generic type, this property always returns true.
The following example creates an instance of a sealed class, checks for the IsSealed property, and displays the result.
using System; namespace SystemType { public class MyClass { // Declare MyTestClass as sealed. sealed public class MyTestClass { } public static void Main(string []args) { try { bool myBool = false; MyTestClass myTestClassInstance = new MyTestClass(); // Get the type of myTestClassInstance. Type myType = myTestClassInstance.GetType(); // Get the IsSealed property of the myTestClassInstance. myBool = myType.IsSealed; Console.WriteLine("\nIs {0} sealed? {1}.", myType.FullName, myBool.ToString()); } catch (Exception e) { Console.WriteLine("\nAn exception occurred: {0}",e.Message); } } } }
