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
