InstanceContext 建構函式

定義

命名空間:

System.ServiceModel

組件:

System.ServiceModel.Duplex.dll

組件:

System.ServiceModel.Primitives.dll

組件:

System.ServiceModel.dll

初始化 InstanceContext 類別的新執行個體。

多載

InstanceContext(Object)	為實作服務執行個體的指定物件，初始化 InstanceContext 類別的新執行個體。
InstanceContext(ServiceHostBase)	為指定主機所裝載的服務，初始化 InstanceContext 類別的新執行個體。
InstanceContext(ServiceHostBase, Object)	為指定物件初始化 InstanceContext 類別的新執行個體，此指定物件實作了服務執行個體，且裝載於指定的主機上。

InstanceContext(Object)

為實作服務執行個體的指定物件，初始化 InstanceContext 類別的新執行個體。

public:
 InstanceContext(System::Object ^ implementation);

public InstanceContext (object implementation);

new System.ServiceModel.InstanceContext : obj -> System.ServiceModel.InstanceContext

Public Sub New (implementation As Object)

參數

implementation

Object

實作服務執行個體的物件。

範例

下列程式碼示範如何傳入 InstanceContext 執行個體來建構 ServiceHost 物件︰

string info = "";

InstanceContext instanceContext = new InstanceContext(serviceHost);
info += "    " + "State: " + instanceContext.State.ToString() + "\n";
info += "    " + "ManualFlowControlLimit: " + instanceContext.ManualFlowControlLimit.ToString() + "\n";
info += "    " + "HashCode: " + instanceContext.GetHashCode().ToString() + "\n";

Console.WriteLine(info);

備註

這會將與執行個體內容相關的服務主機設為 null。

InstanceContext(ServiceHostBase)

為指定主機所裝載的服務，初始化 InstanceContext 類別的新執行個體。

public:
 InstanceContext(System::ServiceModel::ServiceHostBase ^ host);

public InstanceContext (System.ServiceModel.ServiceHostBase host);

new System.ServiceModel.InstanceContext : System.ServiceModel.ServiceHostBase -> System.ServiceModel.InstanceContext

Public Sub New (host As ServiceHostBase)

參數

host

ServiceHostBase

裝載服務的 ServiceHostBase。

例外狀況

ArgumentNullException

host 為 null。

範例

下列程式碼示範如何傳入 InstanceContext 執行個體來建構 ServiceHost 物件︰

string info = "";

InstanceContext instanceContext = new InstanceContext(serviceHost);
info += "    " + "State: " + instanceContext.State.ToString() + "\n";
info += "    " + "ManualFlowControlLimit: " + instanceContext.ManualFlowControlLimit.ToString() + "\n";
info += "    " + "HashCode: " + instanceContext.GetHashCode().ToString() + "\n";

Console.WriteLine(info);

InstanceContext(ServiceHostBase, Object)

為指定物件初始化 InstanceContext 類別的新執行個體，此指定物件實作了服務執行個體，且裝載於指定的主機上。

public:
 InstanceContext(System::ServiceModel::ServiceHostBase ^ host, System::Object ^ implementation);

public InstanceContext (System.ServiceModel.ServiceHostBase host, object implementation);

new System.ServiceModel.InstanceContext : System.ServiceModel.ServiceHostBase * obj -> System.ServiceModel.InstanceContext

Public Sub New (host As ServiceHostBase, implementation As Object)

參數

host

ServiceHostBase

裝載服務的 ServiceHostBase。

implementation

Object

實作服務執行個體的物件。

範例

下列程式碼說明如何先建立服務物件與 InstanceContext 物件，來建立 ServiceHost 物件︰

Uri baseAddress = new Uri("http://localhost:8000/ServiceModelSamples/service");
CalculatorService service = new CalculatorService();
ServiceHost serviceHost = new ServiceHost(service, baseAddress);
InstanceContext instanceContext = new InstanceContext(serviceHost,service);

string info = "";
info += "    " + "State: " + instanceContext.State.ToString() + "\n";
info += "    " + "ManualFlowControlLimit: " + instanceContext.ManualFlowControlLimit.ToString() + "\n";
info += "    " + "HashCode: " + instanceContext.GetHashCode().ToString() + "\n";
Console.WriteLine(info);
