c# new array

[Acceptu]

Morning All

As you can see iv not been around for a while but hope every one is well.

In this little bit of C# im having to count the size of the array i need then create a new array, is there a better way i can do this?

        public string[] getusernames()
        {
            int compcount = 0;
            string[] getusername = new string[100];
            compcount = 0;
            for (int count = 0; count < computer.Length; count++)
            {
                if (!checkifinlist(getusername, computer[count].getusername()))
                {
                    getusername[compcount] = computer[count].getusername();
                    compcount++;
                }
            }
            string[]usernames = new string[compcount];
            compcount = 0;
            for (int count = 0; count < computer.Length; count++)
                    {
                    if(!checkifinlist(usernames, computer[count].getusername())) {
                        usernames[compcount]=computer[count].getusername();
                    compcount++;
                    }
                }
            return usernames;
        }

            int depcount = 0;
            string[] checkdepartments = new string[20];

            for (int count = 0; count < computer.Length; count++)
            {
                if (!checkifinlist(checkdepartments, computer[count].getdepartment()))
                {
                    checkdepartments[depcount] = computer[count].getdepartment();
                    depcount++;
                }
            }
            string[] getdepartments = new string[depcount];

            for (int count = 0; count < depcount; count++)
            {
                getdepartments[count] = checkdepartments[depcount];
            }
            return getdepartments;
