copied!<p>I ended up using gt124's link <a href="http://lozanotek.com/blog/archive/2010/04/16/simple_json_model_binder.aspx" rel="noreferrer">model binder example</a> along with <a href="http://lostechies.com/jimmybogard/2009/03/18/a-better-model-binder/" rel="noreferrer">a better model binder</a> to write my own model binding logic. It ended up looking like this:</p> <pre><code>public interface IFilteredModelBinder : IModelBinder { bool IsMatch(Type modelType); } public class SmartModelBinder : DefaultModelBinder { private readonly IFilteredModelBinder[] _filteredModelBinders; public SmartModelBinder(IFilteredModelBinder[] filteredModelBinders) { _filteredModelBinders = filteredModelBinders; } public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { foreach (var filteredModelBinder in _filteredModelBinders) { if (filteredModelBinder.IsMatch(bindingContext.ModelType)) { return filteredModelBinder.BindModel(controllerContext, bindingContext); } } return base.BindModel(controllerContext, bindingContext); } } public class NewtonsoftJsonModelBinder : IFilteredModelBinder { public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext) { if (!controllerContext.HttpContext.Request.ContentType.StartsWith("application/json", StringComparison.OrdinalIgnoreCase)) { // not JSON request return null; } var request = controllerContext.HttpContext.Request; request.InputStream.Position = 0; var incomingData = new StreamReader(request.InputStream).ReadToEnd(); if (String.IsNullOrEmpty(incomingData)) { // no JSON data return null; } object ret = JsonConvert.DeserializeObject(incomingData, bindingContext.ModelType); return ret; } public bool IsMatch(Type modelType) { var ret = (typeof(JsonModel).IsAssignableFrom(modelType)); return ret; } } </code></pre> <p>I then used JSON.net attributes to map to the different object properties (instead of DataContracts) on the models. The models all inherited from an empty base class JsonModel.</p>
