DiscoveryProxy.BeginShouldRedirectFind 方法

定义

命名空间:

System.ServiceModel.Discovery

程序集:

System.ServiceModel.Discovery.dll

重写此方法以允许发现代理在接收多播查找请求时发出多播禁止消息。

protected:
 virtual IAsyncResult ^ BeginShouldRedirectFind(System::ServiceModel::Discovery::FindCriteria ^ resolveCriteria, AsyncCallback ^ callback, System::Object ^ state);

protected virtual IAsyncResult BeginShouldRedirectFind (System.ServiceModel.Discovery.FindCriteria resolveCriteria, AsyncCallback callback, object state);

abstract member BeginShouldRedirectFind : System.ServiceModel.Discovery.FindCriteria * AsyncCallback * obj -> IAsyncResult
override this.BeginShouldRedirectFind : System.ServiceModel.Discovery.FindCriteria * AsyncCallback * obj -> IAsyncResult

Protected Overridable Function BeginShouldRedirectFind (resolveCriteria As FindCriteria, callback As AsyncCallback, state As Object) As IAsyncResult

参数

resolveCriteria

FindCriteria

用于描述要查找的服务的解析标准。

callback

AsyncCallback

完成操作时要调用的回调委托。

state

Object

用户定义的状态数据。

返回

IAsyncResult

对挂起的异步操作的引用。

注解

当发现代理可用时，可以发送多播禁止消息来响应多播查找或解析消息。 向发现代理发送单播消息有助于减少由发现操作引起的网络流量。
