推荐答案

ASP.NET Web API使用内容协商将输入的HTTP请求自动反序列化为模型类.开箱即用，它将与任何XML，JSON或wwww-form-urlencoded消息一起使用.

ASP.NET Web API uses content negotiation to automatically deserialize an incoming http request into a model class. Out of the box, this this will work with any XML, JSON, or wwww-form-urlencoded message.

public class ComputerController : ApiController
{
    public void Post(ComputerInfo computer)
    {
        // use computer argument
    }
}

创建一个映射到XML属性的模型类.

---

Create a model class which maps to the properties of the XML.

public class ComputerInfo
{
    public string Processor { get; set; }
    public string HardDrive { get; set; }
}

---

此传入的XML将反序列化以在Post方法中混合计算机参数.

---

This incoming XML would be deserialized to hydrate the computer parameter in the Post method.

<ComputerInfo>
   <Processor>AMD</Processor>
   <HardDrive>Toshiba</HardDrive>
</ComputerInfo>

---

如果出于任何原因要手动读取和解析传入的xml，都可以这样做

---

If for whatever reason you want to manually read and parse the incoming xml, you can do so like this

string incomingText = this.Request.Content.ReadAsStringAsync().Result;
XElement incomingXml = XElement.Parse(incomingText);
