static member Connect : Type * string -> obj
Public Shared Function Connect (classToProxy As Type, url As String) As Object

參數

classToProxy
Type

你想 Type 連接的伺服器端一個已知物件。

url
String

伺服器類別的網址。

傳回

Object

指向遠端物件的代理，指向由指定且知名物件服務的端點。

屬性
ComVisibleAttribute SecurityCriticalAttribute

例外狀況

SecurityException

直接呼叫者無權設定遠端通訊類型與通道。

範例

以下程式碼範例示範如何使用此 Connect 方法建立一個已知物件的代理。

Console::WriteLine( "Connecting to SampleNamespace::SampleWellKnown." );
SampleWellKnown ^ proxy = dynamic_cast<SampleWellKnown^>(RemotingServices::Connect( SampleWellKnown::typeid, const_cast<String^>(SERVER_URL) ));
Console::WriteLine( "Connected to SampleWellKnown" );

// Verifies that the Object* reference is to a transparent proxy.
if ( RemotingServices::IsTransparentProxy( proxy ) )
      Console::WriteLine( "proxy is a reference to a transparent proxy." );
else
      Console::WriteLine( "proxy is not a transparent proxy.  This is unexpected." );

// Calls a method on the server Object*.
Console::WriteLine( "proxy->Add returned {0}.", proxy->Add( 2, 3 ) );

Console.WriteLine("Connecting to SampleNamespace.SampleWellKnown.");

SampleWellKnown proxy =
   (SampleWellKnown)RemotingServices.Connect(typeof(SampleWellKnown), SERVER_URL);

Console.WriteLine("Connected to SampleWellKnown");

// Verifies that the object reference is to a transparent proxy.
if (RemotingServices.IsTransparentProxy(proxy))
    Console.WriteLine("proxy is a reference to a transparent proxy.");
else
    Console.WriteLine("proxy is not a transparent proxy.  This is unexpected.");

// Calls a method on the server object.
Console.WriteLine("proxy.Add returned {0}.", proxy.Add(2, 3));

Console.WriteLine("Connecting to SampleNamespace.SampleWellKnown.")

Dim proxy As SampleWellKnown = _
   CType(RemotingServices.Connect(GetType(SampleWellKnown), SERVER_URL), SampleWellKnown)

Console.WriteLine("Connected to SampleWellKnown")

' Verifies that the object reference is to a transparent proxy.
If RemotingServices.IsTransparentProxy(proxy) Then
   Console.WriteLine("proxy is a reference to a transparent proxy.")
Else
   Console.WriteLine("proxy is not a transparent proxy.  This is unexpected.")
End If

' Calls a method on the server object.
Console.WriteLine("proxy.Add returned {0}.", proxy.Add(2, 3))
