Create a method or class that takes a single parameter, the year, and returns the correct string(s) for all requirements.

Yeah. Need example

Use String.Format to create the strings you need, passing in the year number.


String mymethod(int year)
{
    string dbName = String.Format("mydb_{0}", year);
    return dbName;
}

If only the year has to be changed in the connectionstring, you can use .Replace()

C#

string con = Properties.Settings.Default.BSS_2018CS.Replace("2018", "2019");
