Question

我从“ServiceOperation”（WCF数据服务）返回客户端：

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<entry xml:base="http://dd-1620/SampleData.svc/" xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices" xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata" xmlns="http://www.w3.org/2005/Atom">
  <id>http://dd-1620/SampleData.svc/Customers('1001')</id>
  <title type="text"></title>
  <updated>2011-06-21T18:42:05Z</updated>
  <author>
    <name />
  </author>
  <link rel="edit" title="Customer" href="Customers('1001')" />
  <category term="Customer" scheme="http://schemas.microsoft.com/ado/2007/08/dataservices/scheme" />
  <content type="application/xml">
    <m:properties>
      <d:MasterCustomerId>1001</d:MasterCustomerId>
      <d:SubCustomerId>0</d:SubCustomerId>
      <d:FirstName>Jag</d:FirstName>
      <d:LastName>Chat</d:LastName>
    </m:properties>
  </content>
</entry>

我们在执行以下操作时得到以上内容：

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sUri);
req.Credentials = cache;
req.Method = "POST";
req.ContentType = "application/xml";
HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
Stream respStream = resp.GetResponseStream();
StreamReader sr = new StreamReader(resp.GetResponseStream());
string sResp = sr.ReadToEnd();
sr.Close();

当我尝试使用以下内容反序列化它时：

DataContractSerializer dc = new DataContractSerializer(typeof(Customer));
return (Customer)dc.ReadObject(new System.IO.MemoryStream(sResp.ToByteArrayUTF8()));

我收到以下错误：

第1行位置错误249.期望来自名称空间'http://schemas.datacontract.org/2004/07/SampleSvcRef'的元素'Customer'。遇到名为'entry'的'Element'，名称空间'http://www.w3.org/2005/Atom'。

更新：

使用服务引用生成的Customer类如下：

[global::System.Data.Services.Common.EntitySetAttribute("Customers")]
[global::System.Data.Services.Common.DataServiceKeyAttribute("MasterCustomerId")]
public partial class Customer : global::System.ComponentModel.INotifyPropertyChanged

Answer 1

Customer对象需要看起来像这样。

[MetadataType(typeof(MyEntities.Customer))]
[DataContract(Name = "entry")]
public partial Customer
{
  [DataMember(Name = "id")]
  public string Id { get; set; }

  [DataMember(Name = "title")]
  public string Title { get; set; }
}
