RemotingServices.IsObjectOutOfContext(Object) 方法

定义

返回一个布尔值,该值指示给定代理表示的对象是否包含在与调用当前方法的对象不同的上下文中。Returns a Boolean value that indicates whether the object represented by the given proxy is contained in a different context than the object that called the current method.

public:
 static bool IsObjectOutOfContext(System::Object ^ tp);
public static bool IsObjectOutOfContext (object tp);
static member IsObjectOutOfContext : obj -> bool
Public Shared Function IsObjectOutOfContext (tp As Object) As Boolean

参数

tp
Object

要检查的对象。The object to check.

返回

Boolean

如果该对象在当前上下文之外,则为 true;否则为 falsetrue if the object is out of the current context; otherwise, false.

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(
        typeof(TempConverter.Converter),
        "http://localhost:8085/TempConverter");

// Create a local version of TempConverter.Converter.
TempConverter.Converter converter2 = new 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.

                                                   converter1)

' Returns false, converter2 is local and running in this context.

                                                   converter2)

注解

上下文是一系列有序属性,这些属性定义驻留在其中的对象的环境。A context is an ordered sequence of properties that define an environment for the objects that reside inside it. 上下文是在对象的激活过程中创建的,这些对象配置为需要某些自动服务,例如同步、事务、实时激活、安全等。Contexts are created during the activation process for objects that are configured to require certain automatic services such synchronization, transactions, just-in-time activation, security, and so on. 多个对象可以存留在一个上下文内。Multiple objects can live inside a context.
