为已知对象创建一个代理。

重载

Connect(Type, String)	使用给定的 Type 和 URL，为已知对象创建一个代理。
Connect(Type, String, Object)	使用给定的 Type、URL 和信道特定数据，为已知对象创建一个代理。

Connect(Type, String)

使用给定的 Type 和 URL，为已知对象创建一个代理。

public:
 static System::Object ^ Connect(Type ^ classToProxy, System::String ^ url);

public static object Connect (Type classToProxy, string url);

[System.Runtime.InteropServices.ComVisible(true)]
public static object Connect (Type classToProxy, string url);

[System.Runtime.InteropServices.ComVisible(true)]
[System.Security.SecurityCritical]
public static object Connect (Type classToProxy, string url);

static member Connect : Type * string -> obj

[<System.Runtime.InteropServices.ComVisible(true)>]
static member Connect : Type * string -> obj

[<System.Runtime.InteropServices.ComVisible(true)>]
[<System.Security.SecurityCritical>]
static member Connect : Type * string -> obj

Public Shared Function Connect (classToProxy As Type, url As String) As Object

参数

classToProxy: Type

要连接到的位于服务器端的已知对象的 Type。

url: String

服务器类的 URL。

Object

远程对象的代理，指向由指定的已知对象提供的终结点。

属性: ComVisibleAttribute SecurityCriticalAttribute

例外

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 Connect 该方法创建到已知对象的代理。

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))

注解

返回的代理对象指向由指定的已知对象提供的终结点。在代理上调用方法之前，不会通过网络发送消息。

适用于

Connect(Type, String, Object)

使用给定的 Type、URL 和信道特定数据，为已知对象创建一个代理。

public:
 static System::Object ^ Connect(Type ^ classToProxy, System::String ^ url, System::Object ^ data);

public static object Connect (Type classToProxy, string url, object data);

[System.Runtime.InteropServices.ComVisible(true)]
public static object Connect (Type classToProxy, string url, object data);

[System.Runtime.InteropServices.ComVisible(true)]
[System.Security.SecurityCritical]
public static object Connect (Type classToProxy, string url, object data);

static member Connect : Type * string * obj -> obj

[<System.Runtime.InteropServices.ComVisible(true)>]
static member Connect : Type * string * obj -> obj

[<System.Runtime.InteropServices.ComVisible(true)>]
[<System.Security.SecurityCritical>]
static member Connect : Type * string * obj -> obj

Public Shared Function Connect (classToProxy As Type, url As String, data As Object) As Object

参数

classToProxy: Type

要连接到的已知对象的 Type。

url: String

已知对象的 URL。

data: Object

信道特定的数据。可以为 null。

Object

指向由所请求的已知对象提供的终结点的代理。

属性: ComVisibleAttribute SecurityCriticalAttribute

例外
