How can I avoid repeating the same parameters in 2 different methods

The 2 Methods below use exactly the same parameters
The first method-1 users the method to generate a list from database
records using a stored procedure

The second Method-2  uses the same parameters but this time to write or
delete a record

Method-1
 []public static List<LocationModel> GetUsers_Filtered(string locationid,string  locationdes,string thecompany,string dummyidx ,string  dowhat)
        {
            var p = new
            {
                locationidx = locationid,
                locdescriptionx = locationdes,
                companycodex = thecompany,
                idx = Convert.ToInt32(dummyidx),
                dowhatx = dowhat
            };
            return NewDataAccess.ReadData<LocationModel>("public.splocationcode_search", p);
        }[/code]

Method-2       
   []   public static void CreateLocation(string locationvalue, string locdescriptionvalue, string companycodevalue, int idvalue, string dowhatvalue)
        {
            // Note This parameter definition is good for inserts and updates and delete into/From the database
            var p = new
            {
                locationidx = locationvalue,
                locdescriptionx = locdescriptionvalue,
                companycodex = companycodevalue,
                idx = idvalue,
                dowhatx = dowhatvalue   // Can be UI DM or DP ie UpdateInsert, DeleteMarked or DeletePermanent
            };


            switch (LoginDetails.staticinsertupdatedeletetag)
            {
                case "IU":                                  // Update and Inserts Stored Procedure
                    NewDataAccess.WriteData("public.splocationcode_updateinsert", p);
                    break;
                case "DM":                                  //  Delete Marked
                    NewDataAccess.WriteData("public.splocationcode_delete", p);
                    break;
                default:
                    break;
            }

        }[/code]

The 2 methods work as required but i would if possible not like to
repeat the same set of parameters twice.

How can I refactor this code to ensure that the portion below is not repeated twice
 var p = new
            {
                locationidx = locationid,
                locdescriptionx = locationdes,
                companycodex = thecompany,
                idx = Convert.ToInt32(dummyidx),
                dowhatx = dowhat
            };
