Type.IsMarshalByRef Property

Definition

Gets a value indicating whether the Type is marshaled by reference.

public:
 property bool IsMarshalByRef { bool get(); };
public bool IsMarshalByRef { get; }
member this.IsMarshalByRef : bool
Public ReadOnly Property IsMarshalByRef As Boolean

Property Value

true if the Type is marshaled by reference; otherwise, false.

Implements

Examples

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 ContextBoundClass: public ContextBoundObject
{
   public:
      String^ Value;
};

public ref class Example
{
public:
   void Demo()
   {
      // Determine whether the types can be hosted in a Context.
      Console::WriteLine("The IsContextful property for the {0} type is {1}.",
                         Example::typeid->Name, Example::typeid->IsContextful);
      Console::WriteLine("The IsContextful property for the {0} type is {1}.",
                         ContextBoundClass::typeid->Name, ContextBoundClass::typeid->IsContextful);
      
      // Determine whether the types are marshalled by reference.
      Console::WriteLine("The IsMarshalByRef property of {0} is {1}.",
                         Example::typeid->Name, Example::typeid->IsMarshalByRef );
      Console::WriteLine("The IsMarshalByRef property of {0} is {1}.",
                         ContextBoundClass::typeid->Name, ContextBoundClass::typeid->IsMarshalByRef );
      
      // Determine whether the types are primitive datatypes.
      Console::WriteLine("{0} is a primitive data type: {1}.",
                         int::typeid->Name, int::typeid->IsPrimitive );
