c sharp property validation if value is null

hi all, im trying to do a properties validation if a value for my property for example userName is null then i will return an empty string instead of a null value

but if i have lots of properties for an object, do we have to do it like below validation (redundancy), im wondering if this is a good way, can anyone help to advise? thank you so much in advance..

        private string _userName;
        public string userName { 
          get { return _userName; } 
          set { 
            if (string.IsNullOrEmpty(value)) _userName = string.Empty; 
            else _userName = value;
          }
        }

        private string _userName;
        public string userName { 
          get { return _userName; } 
          set { 
            if (string.IsNullOrEmpty(value)) _userName = string.Empty; 
            else _userName = value;
          }
        }
