Multiselect will directly give you array of values Meaning var ddlMulvalues=$( "#mulselectId" ).val(); the above jquery code will give you value of all selected fields as an array so you can directly pass this to you controller using ajax var obj= { MulSelectValues:obj, // other fields } $.ajax({ type: "POST" . url: "/controllerName/endPoint" , dataType: "json" , data:JSON.Stringify( "obj" :obj), sucess:fucnction(){ } }) [httppost( "\endpoint" )] public IActionResult YourMethod(YourClass obj) { var allSelected= obj.MulSelectValues; // now you can loop thorugh and save to DB one by one //or can pass values as comma separated string var CSValues=string.Join( "," , allSelected.ToArray()); } public class YourClass { public List MulSelectValues {get;set;} }

You can pass in the form of comma-separated string from the front end and split in the backend. public IQueryable GetItemByColour( string Colour) { List int > intArr = Array.ConvertAll(Colour.Split( ',' ), s => int .Parse(s)).ToList(); // code more } OR pass data in strings and Deserialized public ActionResult SaveRuleEngine( string strRuleEngine) { RuleGroupViewModel objRuleEngine = Newtonsoft.Json.JsonConvert.DeserializeObject (strRuleEngine); // more code } Or else you can pass in an array public IQueryable GetItemByColour([FromUri] int [] Colour) { // your code } Hope this might help
