通过

RemotingServices.Disconnect 方法

  • 项目

阻止对象通过注册的远程处理信道再接收任何消息。

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

语法

声明
Public Shared Function Disconnect ( _
    obj As MarshalByRefObject _
) As Boolean
用法
Dim obj As MarshalByRefObject
Dim returnValue As Boolean

returnValue = RemotingServices.Disconnect(obj)

public static bool Disconnect (
    MarshalByRefObject obj
)

public:
static bool Disconnect (
    MarshalByRefObject^ obj
)

public static boolean Disconnect (
    MarshalByRefObject obj
)

public static function Disconnect (
    obj : MarshalByRefObject
) : boolean

参数

  • obj
    要与其信道断开连接的对象。

返回值

如果对象与注册的远程处理信道成功断开连接，则为 true；否则为 false。

异常

异常类型 条件

ArgumentNullException

obj 参数为 空引用（在 Visual Basic 中为 Nothing）。

ArgumentException

obj 参数是一个代理。

SecurityException

直接调用方没有配置远程处理类型和通道的权限。

示例

下面的代码示例演示如何使用 Disconnect 方法断开对象与远程处理信道的连接。

Dim channel As New TcpChannel(9000)
ChannelServices.RegisterChannel(channel)

Dim objectWellKnown As New SampleWellKnown()
' After the channel is registered, the object needs to be registered
' with the remoting infrastructure.  So, Marshal is called.
Dim objrefWellKnown As ObjRef = RemotingServices.Marshal(objectWellKnown, "objectWellKnownUri")
Console.WriteLine("An instance of SampleWellKnown type is published at {0}.", objrefWellKnown.URI)

Console.WriteLine("Press enter to unregister SampleWellKnown, so that it is no longer available on this channel.")
Console.ReadLine()
RemotingServices.Disconnect(objectWellKnown)
Console.WriteLine("Press enter to end the server process.")
Console.ReadLine()

TcpChannel channel = new TcpChannel(9000);
ChannelServices.RegisterChannel(channel);

SampleWellKnown objectWellKnown = new SampleWellKnown();

// After the channel is registered, the object needs to be registered
// with the remoting infrastructure.  So, Marshal is called.
ObjRef objrefWellKnown = RemotingServices.Marshal(objectWellKnown, "objectWellKnownUri");
Console.WriteLine("An instance of SampleWellKnown type is published at {0}.", objrefWellKnown.URI);

Console.WriteLine("Press enter to unregister SampleWellKnown, so that it is no longer available on this channel.");
Console.ReadLine();
RemotingServices.Disconnect(objectWellKnown);

Console.WriteLine("Press enter to end the server process.");
Console.ReadLine();

TcpChannel^ channel = gcnew TcpChannel( 9000 );
ChannelServices::RegisterChannel( channel );
SampleWellKnown ^ objectWellKnown = gcnew SampleWellKnown;

// After the channel is registered, the Object* needs to be registered
// with the remoting infrastructure.  So, Marshal is called.
ObjRef^ objrefWellKnown = RemotingServices::Marshal( objectWellKnown, "objectWellKnownUri" );
Console::WriteLine( "An instance of SampleWellKnown type is published at {0}.", objrefWellKnown->URI );
Console::WriteLine( "Press enter to unregister SampleWellKnown, so that it is no longer available on this channel." );
Console::ReadLine();
RemotingServices::Disconnect( objectWellKnown );
Console::WriteLine( "Press enter to end the server process." );
Console::ReadLine();
