I want to use DataContractSerializer to serialize the responses and XmlSerializer to deserialize the xml in incoming requests. Is it possible? I know I can use different serializers for different types but I want different serializers for read and write.

That seems like a really odd request, but yes it's possible. You can create a custom MediaType formatter like this:
public class DcsXsFormatter : MediaTypeFormatter
{
public DataContractXmlFormatter()
{
SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/xml"));
SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("text/xml"));
}
public override bool CanWriteType(Type type)
{
return true;
}
public override bool CanReadType(Type type)
{
return true;
}
public override Task<object> ReadFromStreamAsync(Type type, Stream readStream,
HttpContent content,
IFormatterLogger formatterLogger)
{
var task = Task<object>.Factory.StartNew(() =>
{
var ser = new XmlSerializer(type);
return ser.Deserialize(readStream);
});
return task;
}
public override Task WriteToStreamAsync(Type type, object value,
Stream writeStream,
HttpContent content,
TransportContext transportContext)
{
var task = Task.Factory.StartNew( () =>
{
var ser = new DataContractSerializer(type);
ser.WriteObject(writeStream,value);
writeStream.Flush();
});
return task;
}
}
To hook it up in global.asax:
// remove existing XmlFormatter config.Formatters.Remove(config.Formatters.XmlFormatter);
// Hook in your custom XmlFormatter
config.Formatters.Insert(0, new DcsXsFormatter());
But why would you want to do this?
