c# - SoapHttpClientProtocol/HttpWebClientProtocol 连接状态

Question

我有一个基于 SoapHttpClientProtocol 的 Web 服务引用 (.NET CF 3.5)。我的问题是——除了调用 web 方法之外，有没有办法确定是否建立了与 WebService 的连接？我可以随时检查底层连接是否已建立并获取其状态吗？

您可以在客户端查看通信状态。

using (XServiceSoapClient client = new XServiceSoapClient())
{
   client.State;
}

public enum CommunicationState
{
    // Summary:
    //     Indicates that the communication object has been instantiated and is configurable,
    //     but not yet open or ready for use.
    Created = 0,
    //
    // Summary:
    //     Indicates that the communication object is being transitioned from the System.ServiceModel.CommunicationState.Created
    //     state to the System.ServiceModel.CommunicationState.Opened state.
    Opening = 1,
    //
    // Summary:
    //     Indicates that the communication object is now open and ready to be used.
    Opened = 2,
    //
    // Summary:
    //     Indicates that the communication object is transitioning to the System.ServiceModel.CommunicationState.Closed
    //     state.
    Closing = 3,
    //
    // Summary:
    //     Indicates that the communication object has been closed and is no longer
    //     usable.
    Closed = 4,
    //
    // Summary:
    //     Indicates that the communication object has encountered an error or fault
    //     from which it cannot recover and from which it is no longer usable.
    Faulted = 5,
}
