ASP.NET MVC How to convert ModelState errors to json

Question

How do you get a list of all ModelState error messages? I found this code to get all the keys: ( Returning a list of keys with ModelState errors)

var errorK         


        

Answer 1

  List Errors = new List(); 


        //test errors.
        var modelStateErrors = this.ModelState.Keys.SelectMany(key => this.ModelState[key].Errors);

        foreach (var x in modelStateErrors)
        {
            var errorInfo = new ErrorList()
            {
                ErrorMessage = x.ErrorMessage
            };
            Errors.Add(errorInfo);

        }

if you use jsonresult then return

return Json(Errors);

or you can simply return the modelStateErrors, I havent tried it. What I did is assign the Errors collection to my ViewModel and then loop it..In this case I can return my Errors via json. I have a class/model, I wanted to get the source/key but I'm still trying to figure it out.

    public class ErrorList
{
    public string ErrorMessage;
}
