ServiceStack使用.NET的XML DataContract序列化器.除了基础.NET框架实现提供的内容之外,它不可定制. @H_404_1@为了支持自定义请求,您可以覆盖默认请求处理.
ServiceStack的Serialization and Deserialization wiki page显示了自定义请求处理的不同方法：

@H_404_1@注册自定义请求DTO活页夹

base.RequestBinders.Add(typeof(MyRequest),httpReq => ... requestDto);

@H_404_1@跳过自动反序列化并直接从Request InputStream中读取

@H_404_1@告诉ServiceStack跳过反序列化并自己处理它,让你的DTO实现IRequiresRequestStream并自己反序列化请求(在你的服务中)：

//Request DTO
public class Hello : IRequiresRequestStream
{
    /// <summary>
    /// The raw Http Request Input Stream
    /// </summary>
    Stream RequestStream { get; set; }
}

@H_404_1@覆盖默认的XML Content-Type格式

@H_404_1@如果您更喜欢使用其他XML Serializer,则可以在registering your own Custom Media Type之前覆盖ServiceStack中的默认内容类型,例如：

string contentType = "application/xml";
var serialize = (IRequest request,object response,Stream stream) => ...;
var deserialize = (Type type,Stream stream) => ...;

//In AppHost.Configure method pass two delegates for serialization and deserialization
this.ContentTypes.Register(contentType,serialize,deserialize);
