.NET客户端通过服务引用访问服务时出错

我试图通过.Net客户端应用程序中的服务引用访问服务。 当我访问服务方法时，我得到以下错误：

访问服务方法时捕获异常

从中捕获System.Xml.XmlException消息=结束元素“Body” 名称空间'http://schemas.xmlsoap.org/soap/envelope/”他说。建立 命名空间中的元素“ns:updateStatusAsReadResponse”

我的app.config如下所示：

<bindings>
  <basicHttpBinding>
      <binding name="documentproxySoap11Binding" closeTimeout="00:01:00"
             openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"

你能把你的客户端调用服务的代码和你的客户端配置贴出来吗？我的客户端通过服务引用访问服务。所以它会自动创建一个类。我正在使用class方法。DocumentProxy测试=新DocumentProxy；更新状态试验；maxBytesPerRead=4096 maxNameTableCharCount=16384/>
