示例

下面的代码示例演示如何使用 ActivatedClientTypeEntry 注册客户端激活的远程对象。该示例包含三个部分：客户端、服务器以及客户端和服务器使用的远程对象。

以下代码示例演示客户端：

#using <System.Runtime.Remoting.dll>
#using <ActivatedClientTypeEntry_Share.dll>

using namespace System;
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Tcp;
static void main()
{
   // Register TCP Channel.
   ChannelServices::RegisterChannel( gcnew TcpChannel );
   
   // Create activated client type entry.
   ActivatedClientTypeEntry^ activatedClientTypeEntry = gcnew ActivatedClientTypeEntry( HelloServer::typeid, "tcp://localhost:8082" );
   
   // Register type on client to activate it on the server.
   RemotingConfiguration::RegisterActivatedClientType( activatedClientTypeEntry );
   
   // Activate a client activated object type.
   HelloServer^ helloServer = gcnew HelloServer( "ParameterString" );
   
   // Print the object type.
   Console::WriteLine( "Object type of client activated object: {0}", activatedClientTypeEntry->ObjectType->ToString() );
   
   // Print the application URL.
   Console::WriteLine( "Application url where the type is activated: {0}", activatedClientTypeEntry->ApplicationUrl->ToString() );
   
   // Print the string representation of the type entry.
   Console::WriteLine( "Type and assembly name and application URL of the remote object: {0}", activatedClientTypeEntry->ToString() );
   
   // Print a blank line.
   Console::WriteLine();
   
   // Check that server was located.
   if (  !helloServer )
   {
      Console::WriteLine( "Could not locate server" );
   }
   else
   {
      Console::WriteLine( "Calling remote object" );
      Console::WriteLine( helloServer->HelloMethod( "Bill" ) );
   }
}

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

public class MyClient
{
    public static void Main()
    {
        // Register TCP Channel.
        ChannelServices.RegisterChannel(new TcpChannel());

        // Create activated client type entry.
        ActivatedClientTypeEntry myActivatedClientTypeEntry =
            new ActivatedClientTypeEntry(typeof(HelloServer),
            "tcp://localhost:8082");

        // Register type on client to activate it on the server.
        RemotingConfiguration.RegisterActivatedClientType(
            myActivatedClientTypeEntry);

        // Activate a client activated object type.
        HelloServer myHelloServer = new HelloServer("ParameterString");

        // Print the object type.
        Console.WriteLine(
            "Object type of client activated object: " +
            myActivatedClientTypeEntry.ObjectType.ToString());

        // Print the application URL.
        Console.WriteLine(
            "Application url where the type is activated: " +
            myActivatedClientTypeEntry.ApplicationUrl);

        // Print the string representation of the type entry.
        Console.WriteLine(
            "Type name, assembly name and application URL " +
            "of the remote object: " +
            myActivatedClientTypeEntry.ToString());

        // Print a blank line.
        Console.WriteLine();

        // Check that server was located.
        if (myHelloServer == null)
        {
            Console.WriteLine("Could not locate server");
        }
        else
        {
            Console.WriteLine("Calling remote object");
            Console.WriteLine(myHelloServer.HelloMethod("Bill"));
        }
    }
}

Imports System.Runtime.Remoting
Imports System.Runtime.Remoting.Channels
Imports System.Runtime.Remoting.Channels.Tcp

Public Class MyClient
    
    Public Shared Sub Main()
        ' Register TCP Channel.
        ChannelServices.RegisterChannel(New TcpChannel())

        ' Create activated client type entry.
        Dim myActivatedClientTypeEntry As _
            New ActivatedClientTypeEntry(GetType(HelloServer), _
            "tcp://localhost:8082")

        ' Register type on client to activate it on the server.
        RemotingConfiguration.RegisterActivatedClientType( _
            myActivatedClientTypeEntry)

        ' Activate a client activated object type.
        Dim myHelloServer As New HelloServer("ParameterString")

        ' Print the object type.
        Console.WriteLine("Object type of client activated object: " + _
            myActivatedClientTypeEntry.ObjectType.ToString())

        ' Print the application URL.
        Console.WriteLine("Application url where the type is activated: " + _
            myActivatedClientTypeEntry.ApplicationUrl)

        ' Print the string representation of the type entry.
        Console.WriteLine( _
            "Type name, assembly name and application URL " + _
            "of the remote object: " + _
            myActivatedClientTypeEntry.ToString())

        ' Print a blank line.
        Console.WriteLine()

        ' Check that server was located.
        If myHelloServer Is Nothing Then
            Console.WriteLine("Could not locate server")
        Else
            Console.WriteLine("Calling remote object")
            Console.WriteLine(myHelloServer.HelloMethod("Bill"))
        End If
    End Sub
End Class

以下代码示例演示此客户端的服务器：

#using <ActivatedClientTypeEntry_Share.dll>
#using <System.Runtime.Remoting.dll>

using namespace System;
using namespace System::Runtime::Remoting;
using namespace System::Runtime::Remoting::Channels;
using namespace System::Runtime::Remoting::Channels::Tcp;
void main()
{
   ChannelServices::RegisterChannel( gcnew TcpChannel( 8082 ) );
   RemotingConfiguration::RegisterActivatedServiceType( HelloServer::typeid );
   Console::WriteLine( "Press enter to stop this process" );
   Console::ReadLine();
}

using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;

public class MyServer
{
    public static void Main()
    {
        ChannelServices.RegisterChannel(new TcpChannel(8082));
        RemotingConfiguration.RegisterActivatedServiceType(typeof(HelloServer));
        Console.WriteLine("Press enter to stop this process");
        Console.ReadLine();
   }
}

Imports System.Runtime.Remoting
Imports System.Runtime.Remoting.Channels
Imports System.Runtime.Remoting.Channels.Tcp

Public Class MyServer
    
    Public Shared Sub Main()
        ChannelServices.RegisterChannel(New TcpChannel(8082))
        RemotingConfiguration.RegisterActivatedServiceType(GetType(HelloServer))
        Console.WriteLine("Press enter to stop this process")
        Console.ReadLine()
    End Sub

End Class

下面的代码示例提供客户端和服务器使用的远程对象：

using namespace System;
public ref class HelloServer: public MarshalByRefObject
{
public:
   HelloServer( String^ myString )
   {
      Console::WriteLine( "HelloServer activated" );
      Console::WriteLine( "Paramater passed to the constructor is {0}", myString );
   }

   String^ HelloMethod( String^ myName )
   {
      Console::WriteLine( "HelloMethod : {0}", myName );
      return String::Format( "Hi there {0}", myName );
   }

};

using System;
public class HelloServer : MarshalByRefObject
{
    public HelloServer(String myString)
    {
        Console.WriteLine("HelloServer activated");
        Console.WriteLine("Parameter passed to the constructor is "+myString);
    }
    public String HelloMethod(String myName)
    {
        Console.WriteLine("HelloMethod : {0}",myName);
        return "Hi there " + myName;
    }
}

Public Class HelloServer
    Inherits MarshalByRefObject
    
    Public Sub New(myString As String)
        Console.WriteLine("HelloServer activated")
        Console.WriteLine("Parameter passed to the constructor is " + myString)
    End Sub
    
    Public Function HelloMethod(myName As String) As String
        Console.WriteLine("HelloMethod : {0}", myName)
        Return "Hi there " + myName
    End Function 'HelloMethod
End Class

注解

若要在客户端上创建客户端激活对象的实例，必须知道它 Type ，并且必须使用方法在客户端 RegisterActivatedClientType 上注册它。若要获取客户端激活对象的新实例的代理，客户端必须先注册 ChannelServices 通道，然后通过调用 new来激活对象。

若要使用 new 关键字 (keyword) 激活客户端激活的对象类型，必须先使用 RegisterActivatedClientType 方法在客户端上注册对象类型。通过调用 RegisterActivatedClientType ，可以向远程处理基础结构提供尝试创建远程应用程序 new 的位置。另一方面，如果使用 Activator.CreateInstance 方法创建客户端激活对象的新实例，则必须提供远程应用程序的 URL 作为参数，因此无需事先在客户端上注册。若要为方法提供 Activator.CreateInstance 要在其中创建对象的服务器的 URL，必须在类的 UrlAttribute 实例中封装 URL。

有关客户端激活对象和远程对象激活的详细说明，请参阅远程对象的激活。
