示例
// Create a remote version of TempConverter::Converter.
TempConverter::Converter^ converter1 =
dynamic_cast<TempConverter::Converter^>(Activator::GetObject(
TempConverter::Converter::typeid,
"http://localhost:8085/TempConverter" ));
// Create a local version of TempConverter::Converter.
TempConverter::Converter^ converter2 = gcnew TempConverter::Converter;
// Returns true, converter1 is remote and in a different appdomain.
System::Runtime::Remoting::RemotingServices::IsObjectOutOfAppDomain( converter1 );
// Returns false, converter2 is local and running in this appdomain.
System::Runtime::Remoting::RemotingServices::IsObjectOutOfAppDomain( converter2 );
// Returns true, converter1 is remote and in a different context.
System::Runtime::Remoting::RemotingServices::IsObjectOutOfContext( converter1 );
// Returns false, converter2 is local and running in this context.
System::Runtime::Remoting::RemotingServices::IsObjectOutOfContext( converter2 );
// Create a remote version of TempConverter.Converter.
TempConverter.Converter converter1 =
(TempConverter.Converter) Activator.GetObject(

// Create a local version of TempConverter.Converter.

// Returns false, converter2 is local and running in this appdomain.

上下文是一个有序的属性序列,这些属性为驻留在其中的对象定义环境。 上下文是在激活过程中为配置为需要某些自动服务(如同步、事务、实时激活、安全性等)的对象创建的。 多个对象可以存留在一个上下文内。
