I've adapted the code from Leniel Macaferi a little bit so you can use it for any type:

public class RequestModelBinder : IModelBinder
{
    public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        ValueProviderResult valueResult = bindingContext.ValueProvider
            .GetValue(bindingContext.ModelName);

        ModelState modelState = new ModelState { Value = valueResult };

        object actualValue = null;

        if (valueResult.AttemptedValue != string.Empty)
        {
            try
            {
                // values really should be invariant
                actualValue = Convert.ChangeType(valueResult.AttemptedValue, typeof(TBinding), CultureInfo.CurrentCulture);
            }
            catch (FormatException e)
            {
                modelState.Errors.Add(e);
            }
        }

        bindingContext.ModelState.Add(bindingContext.ModelName, modelState);

        return actualValue;
    }
}
