How can I pass arguments to the constructor

public class MsgIdGatewayTimeMap
        {
            string msgId;
            double gatewayTime;
           
            public string MsgId
            {
                get
                {
                    if (!String.IsNullOrEmpty(msgId))
                        return msgId.ToUpper();
                    else
                        return string.Empty;
                }

                set { msgId = value; }
            }

            public double GatewayTime
            {
                get
                {
                    //Double.IsNullOrEmpty(timeStamp)
                    return gatewayTime;
                    //else
                    //    return string.Empty;
                }

                set { gatewayTime = value; }
            }

            public MsgIdGatewayTimeMap(string msgId, double gatewayTime)
            {
                
                this.msgId = msgId;
                this.gatewayTime = gatewayTime;

            }

        }

for (int Index = 0; Index < cmnMsgIdsRYbuses.Count; Index++)
                {
                    GatewayTimeRYlist.Add(new MsgIdGatewayTimeMap(cmnMsgIdsRYbuses, GatewayTimeRYbuses));
                }
