Model validate date format in c# asp.net web api

I am mapping the web api Get request complex type input parameter with a model and I want to validate the date format of the input type in the model.

My input uri is as follows http://localhost:xxxx/api/games/?id=5&date=2018-01-17

In my GameController

public IHttpActionResult Get([FromUri]Gamedata) {

 if (ModelState.IsValid) {
 }
 else {

 }
}

In my model class

public class Game
    {
        [Required]
        public int? Id { get; set; }

        [Required]
        public string date { get; set; } // Validate the date format "YYYY-MM-DD"


}

I would like to validate the date format "YYY-MM-DD". How this can be achieved? I am reading this. But don't know which is the annotation to be used?

You can do this 

 [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]

In your model

    public class Game
    {
        [Required]
        public int? Id { get; set; }

        [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
        public DateTime date { get; set; } // Validate the date format "YYYY-MM-DD"
     }

You can also look at DateTime.GetDateTimeFormats Method ()
