RemotingServices.IsObjectOutOfContext 方法

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。

**命名空间:**System.Runtime.Remoting
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public Shared Function IsObjectOutOfContext ( _
    tp As Object _
) As Boolean
用法
Dim tp As Object
Dim returnValue As Boolean

returnValue = RemotingServices.IsObjectOutOfContext(tp)

public static bool IsObjectOutOfContext (
    Object tp
)

public:
static bool IsObjectOutOfContext (
    Object^ tp
)

public static boolean IsObjectOutOfContext (
    Object tp
)

public static function IsObjectOutOfContext (
    tp : Object
) : boolean

参数

• tp
  要检查的对象。

返回值

如果该对象在当前上下文之外，则为 true；否则为 false。

备注

上下文是已排序的一系列属性，这些属性为驻留在其中的对象定义环境。上下文是在对象的激活过程中创建的，这些对象被配置为要求某些自动化服务，例如同步、事务、实时激活、安全性等。多个对象可以存在于一个上下文中。
