Question

我试图覆盖标头以在此WebService中调用 push 方法，但是定义中不存在IContextChannel InnerChannel参数。

我按照以下链接中的文章响应所指示的方式创建了SecurityHeader类： https://stackoverflow.com/a/16031437/11505984。但是我不明白InnerChannel的来源。

try
{
    TransmissionService transmission = new TransmissionService();
    using (new OperationContextScope(transmission.InnerChannel))
    {
        OperationContext.Current.OutgoingMessageHeaders.Add(
            new SecurityHeader("UsernameToken-8", "12345/userID", "password123"));
        transmission.publish(new Transmission());
    }
}
catch(Exception e)
{
    var message = e.Message;
}

我遇到以下错误：TransmissionService不包含InnerChannel的定义，也没有扩展方法。

有人可以告诉我我需要什么吗？

谢谢

尝试将TransmissionService投射到IContextChannel：

try
{
    TransmissionService transmission = new TransmissionService();
    using (new OperationContextScope((IContextChannel) transmission))
    {
        OperationContext.Current.OutgoingMessageHeaders.Add(
            new SecurityHeader("UsernameToken-8", "12345/userID", "password123"));
        transmission.publish(new Transmission());
    }
}
catch(Exception e)
{
    var message = e.Message;
}

IContextChannel client.InnerChannel哪里来自此WSDL？
