如何在WCF服务中无依赖地读取多部分/表单数据post流

<system.serviceModel>
  <services>
    <service name="YourServiceName">
      <endpoint address="" binding="webHttpBinding" contract="YourContractName" behaviorConfiguration="webBehavior" />
    </service>
  </services>
  <behaviors>
    <endpointBehaviors>
      <behavior name="webBehavior">
        <webHttp />
      </behavior>
    </endpointBehaviors>
  </behaviors>
</system.serviceModel>

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "UploadData")]
void UploadData(Stream data);

public void UploadData(Stream data)
{
    var provider = new MultipartFormDataStreamProvider("YourUploadDirectory");
    var task = Request.Content.ReadAsMultipartAsync(provider);
    task.Wait();

    foreach (var file in provider.FileData)
    {
        // 处理上传的文件
    }

    foreach (var key in provider.FormData.AllKeys)
    {
        var value = provider.FormData.GetValues(key).FirstOrDefault();
        // 处理表单数据
    }
}
