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.
ASP.NET Web API 使用内容协商自动将传入的 http 请求反序列化为模型类。开箱即用，这将适用于任何 XML、JSON 或 wwww-form-urlencoded 消息。
public class ComputerController : ApiController
{
public void Post(ComputerInfo computer)
{
// use computer argument
}
}
Create a model class which maps to the properties of the XML.
创建一个映射到 XML 属性的模型类。
public class ComputerInfo
{
public string Processor { get; set; }
public string HardDrive { get; set; }
}
This incoming XML would be deserialized to hydrate the computer parameter in the Post method.
这个传入的 XML 将被反序列化以在 Post 方法中混合计算机参数。
<ComputerInfo>
<Processor>AMD</Processor>
<HardDrive>Toshiba</HardDrive>
</ComputerInfo>
If for whatever reason you want to manually read and parse the incoming xml, you can do so like this
如果出于某种原因您想手动读取和解析传入的 xml，您可以这样做
string incomingText = this.Request.Content.ReadAsStringAsync().Result;
XElement incomingXml = XElement.Parse(incomingText);

Any incoming content can be read as a stream of bytes and then processed as required.
任何传入的内容都可以作为字节流读取，然后根据需要进行处理。
public async Task<HttpResponseMessage> Get() {
var stream = await Request.Content.ReadAsStreamAsync();
var xmlDocument = new XmlDocument();
xmlDocument.Load(stream);
// Process XML document
return new HttpResponseMessage();
}
