Question

我正在尝试为我们的Intranet上托管的Web服务创建一个简单的WCF客户端（C＃）。使用Fiddler和SoapUI我可以看到请求和响应似乎没问题，但是当我运行代码时，会返回一个空数组。

我会尝试仅粘贴相关的行（但是会有很多东西），但随便问我是否错过了什么：

WSDL ：

      </s0:port>

</s0:definitions>

绑定配置：

<basicHttpBinding>
  <binding name="Workforce_2_1_0SoapBinding" 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="Mtom" textEncoding="utf-8" transferMode="Buffered"
      useDefaultWebProxy="true">
    <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
        maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    <security mode="TransportCredentialOnly">
      <transport clientCredentialType="Basic" proxyCredentialType="None"
          realm="" />
      <message clientCredentialType="UserName" algorithmSuite="Default" />
    </security>
  </binding>
</basicHttpBinding>

端点：

<endpoint address="http://server123.enterprise.com:31900/MyService/Services/Workforce_2-1-0"
    binding="basicHttpBinding" bindingConfiguration="Workforce_2_1_0SoapBinding"
    contract="Workforce.Workforce_2_1_0PT" name="Workforce_2_1_0SoapPort" />

请求（通过Fiddler）：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <getByKey xmlns="ld:Logical/Workforce_2_1_0_ws">
            <key>ABCDEFGH</key>
        </getByKey>
    </s:Body>
</s:Envelope>

回复（通过Fiddler）：

<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'>
    <soapenv:Header></soapenv:Header>
    <soapenv:Body>
        <ns:getByKeyResponse xmlns:ns='ld:Logical/Workforce_2_1_0_ws'>
            <ns0:basicWorkforce xmlns:ns0="http://schemata.enterprise.biz/hr/2.1">
                <ns0:key>ABCDEFGH</ns0:key>
                <ns0:name>JUAN PABLO MONTOYA</ns0:name>
            </ns0:basicWorkforce>
        </ns:getByKeyResponse>
    </soapenv:Body>
</soapenv:Envelope>

客户代码：

Workforce_2_1_0PTClient client = new Workforce_2_1_0PTClient();

client.ClientCredentials.UserName.UserName = "MyUsername";
client.ClientCredentials.UserName.Password = "MyPassword";

var result = client.getByKey("ABCDEFGH");

            this.RaisePropertyChanged("name");
        }
    }
}

即使回复包含一个basicWorkforce元素，result变量也是basicWorkforce的空数组。

对于长篇文章感到抱歉，并提前感谢您的帮助。

Answer 1

终于做到了！对于任何面临同样问题的人来说，它位于命名空间上。在这种情况下，在getByKeyResponse返回的数组上。

所以，我刚刚取代了这个：

    [System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://schemata.enterprise.biz/hr/2.1", Order=0)]
    [System.Xml.Serialization.XmlElementAttribute("basicWorkforce")]
    public basicWorkforce[] basicWorkforce;

用这个：

    [System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://schemata.enterprise.biz/hr/2.1", Order=0)]
    [System.Xml.Serialization.XmlElementAttribute("basicWorkforce", Namespace = "http://schemata.enterprise.biz/hr/2.1")]
    public basicWorkforce[] basicWorkforce;

Answer 2

您是否已将收集类型设为System.Array
它在添加服务参考中 - ＆gt;高级
或
在服务参考 - ＆gt;配置服务引用。

WCF客户端返回空数组 - XML响应似乎没问题
