国外某牛人的JsonModelBinder 实现 MVC 3.0

public class JsonModelBinder : DefaultModelBinder
{
public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{

if (!IsJSONRequest(controllerContext))
{
return base.BindModel(controllerContext, bindingContext);
}

// Get the JSON data that's been posted
var request = controllerContext.HttpContext.Request;
var jsonStringData = new StreamReader(request.InputStream).ReadToEnd();
return new JavaScriptSerializer().Deserialize(jsonStringData, bindingContext.ModelMetadata.ModelType);

}

private static bool IsJSONRequest(ControllerContext controllerContext)
{
var contentType = controllerContext.HttpContext.Request.ContentType;
return contentType.Contains("FTchinaMVC/json");
}
}

protected void Application_Start()
{
ModelBinders.Binders.DefaultBinder = new JsonModelBinder();
RegisterRoutes(RouteTable.Routes);
}
AreaRegistration.RegisterAllAreas();

RegisterGlobalFilters(GlobalFilters.Filters);
