Type::IsContextful Property

Gets a value indicating whether the Type can be hosted in a context.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public:
virtual property bool IsContextful {
	bool get () sealed;
}

Property Value

Type: System::Boolean
true if the Type can be hosted in a context; otherwise, false.

Implements

_Type::IsContextful

A context intercepts calls to the class members and enforces policies that are applied to the class, such as synchronization. For more detailed information on remoting contexts, see Context.

If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.

The following example demonstrates the IsContextful, IsMarshalByRef, and IsPrimitive properties of the Type class. It checks whether the given type can be hosted in the context, whether it can be marshaled by reference, and whether the type is a primitive data type.


using namespace System;
using namespace System::Runtime::Remoting::Contexts;
public ref class MyContextBoundClass: public ContextBoundObject
{
public:
   String^ myString;
};

public ref class MyTypeDemoClass
{
public:
   void Demo()
   {
      try
      {
         // Determine whether the types can be hosted in a Context.
         Console::WriteLine( "The IsContextful property for the {0} type is {1}.", MyTypeDemoClass::typeid->Name, MyTypeDemoClass::typeid->IsContextful );
         Console::WriteLine( "The IsContextful property for the {0} type is {1}.", MyContextBoundClass::typeid->Name, MyContextBoundClass::typeid->IsContextful );

         // Determine whether the types are marshalled by reference.
         Console::WriteLine( "The MarshalByRef property of {0} is {1}.", MyTypeDemoClass::typeid->Name, MyTypeDemoClass::typeid->IsMarshalByRef );
         Console::WriteLine( "The MarshalByRef property of {0} is {1}.", MyContextBoundClass::typeid->Name, MyContextBoundClass::typeid->IsMarshalByRef );

         // Determine whether the types are primitive datatypes.
         Console::WriteLine( "Is {0} is a primitive data type? {1}.", int::typeid->Name, int::typeid->IsPrimitive );
         Console::WriteLine( "Is {0} a primitive data type? {1}.", String::typeid->Name, String::typeid->IsPrimitive );
      }
      catch ( Exception^ e ) 
      {
         Console::WriteLine( "An exception occurred: {0}", e->Message );
      }
   }
};

int main()
{
   MyTypeDemoClass^ mtdc = gcnew MyTypeDemoClass;
   mtdc->Demo();
}
