The following example creates an instance of a sealed class, checks for the IsSealed property, and displays the result.
using namespace System; // Declare MyTestClass as sealed. ref class MyTestClass sealed{}; int main() { try { bool myBool = false; MyTestClass^ myTestClassInstance = gcnew 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 ); } catch ( Exception^ e ) { Console::WriteLine( "\nAn exception occurred: {0}", e->Message ); } }
package SystemType;
import System.*;
public class MyClass
{
// Declare MyTestClass as sealed.
final public static class MyTestClass
{
} //MyTestClass
public static void main(String[] args)
{
try {
boolean myBool = false;
MyTestClass myTestClassInstance = new MyTestClass();
// Get the type of myTestClassInstance.
Type myType = myTestClassInstance.GetType();
// Get the IsSealed property of the myTestClassInstance.
myBool = myType.get_IsSealed();
Console.WriteLine("\nIs {0} sealed? {1}.", myType.get_FullName(),
System.Convert.ToString(myBool));
}
catch (System.Exception e) {
Console.WriteLine("\nAn exception occurred: {0}", e.get_Message());
}
} //main
} //MyClass
