c# - 使用soap客户端时出现InvalidOperationException

Question

我已使用 vs2008 中的添加服务引用对话框添加为 wsdl 文件。

MyService serviceproxy = new MyService();

当我实例化服务代理时，我收到一个 InvalidOperationException ，其中包含以下文本(翻译自德语):

Could not find default endpoint element to the contract "ServiceName.ServiceInterface" in the service model refers client configuration section. This may be because: The application configuration file was not found or not an endpoint in the client element item is found, which corresponded to this contract.

其中servicename是我在vs2008中添加服务时给服务起的名称，ServiceInterface是为其自动生成的接口(interface)。

编辑 这是我的 app.config 中的内容:

<system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="MyServiceBinding" closeTimeout="00:01:00"
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                    allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
                    maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536"
                    messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered"
                    useDefaultWebProxy="true">
                    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
                    <security mode="None">
                        <transport clientCredentialType="None" proxyCredentialType="None"
                            realm="" />
                        <message clientCredentialType="UserName" algorithmSuite="Default" />
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
    </system.serviceModel>

你的配置中需要这样的东西:

<client>
  <endpoint binding="basicHttpBinding" 
    bindingConfiguration="MyServiceBinding" contract="ServiceName.ServiceInterface"
    name="MyServiceEndpoint">
  </endpoint>
</client>

我刚刚读了你的评论。

因此从端点配置中删除了地址。

您可以选择在代码中完全指定端点或仅指定地址，如下所示:

MyServiceClient proxy = new MyServiceClient();
proxy.Endpoint.Address = new EndpointAddress ("http://addressto your service"); //<-- address
