InstanceContext 构造函数

定义

命名空间:

System.ServiceModel

程序集:

System.ServiceModel.Duplex.dll

程序集:

System.ServiceModel.Primitives.dll

程序集:

System.ServiceModel.dll

初始化 InstanceContext 类的新实例。

重载

InstanceContext(Object)	为实现服务实例的指定对象初始化 InstanceContext 类的新实例。
InstanceContext(ServiceHostBase)	为指定主机承载的服务初始化 InstanceContext 类的新实例。
InstanceContext(ServiceHostBase, Object)	为实现服务实例并且由指定主机承载的指定对象初始化 InstanceContext 类的新实例。

InstanceContext(Object)

为实现服务实例的指定对象初始化 InstanceContext 类的新实例。

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

public InstanceContext (object implementation);

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

Public Sub New (implementation As Object)

参数

implementation

Object

实现服务实例的对象。

示例

下面的代码演示如何通过传入 InstanceContext 实例构造 ServiceHost 对象。

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);

注解

这将与实例上下文关联的服务主机设置为 null。

InstanceContext(ServiceHostBase)

为指定主机承载的服务初始化 InstanceContext 类的新实例。

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)

参数

host

ServiceHostBase

承载服务的 ServiceHostBase。

例外

ArgumentNullException

host 为 null。

示例

下面的代码演示如何通过传入 InstanceContext 实例构造 ServiceHost 对象。

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)

为实现服务实例并且由指定主机承载的指定对象初始化 InstanceContext 类的新实例。

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)

参数

host

ServiceHostBase

承载服务的 ServiceHostBase。

implementation

Object

实现服务实例的对象。

示例

下面的代码演示如何通过先创建服务对象和 InstanceContext 对象来创建 ServiceHost 对象：

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);
