how can I write a c# program to draw a league table

Did you want a way of pairing up the teams? If so, i came up with this. I created a simple simple windows forms app with only a Button and TextBox control set to display as multiline. The button's click event runs the function CreateFixtures().
I know more can be done to take the teams as teams names when the program runs and also the actual scheduling. I can add it later.

        private void CreateFixtures()
        {
            List fixtures = new List();
            string[] teams = { "A", "B", "C", "D" };
            foreach (string x in teams)
                foreach (string y in teams)
                {
                    if (x != y)
                    {
                        string teampair = MakePair(x, y);
                        if (!FixtureExists(x, y, fixtures))
                            fixtures.Add(teampair);
                    }
                }
            PrintResults(fixtures);
        }
        private string MakePair(string teamx, string teamy)
        {
            return teamx + " - " + teamy;
        }
        private bool FixtureExists(string team1, string team2, List lstFixtures)
        {
            bool isleftmatch = lstFixtures.Exists(delegate(string s) { return s == MakePair(team1, team2); });
            if (!isleftmatch)
            {
                bool rightmatch = lstFixtures.Exists(delegate(string s) { return s == MakePair(team2, team1); });
                isleftmatch = rightmatch;
            }
            return isleftmatch;
        }
        private void PrintResults(List fixturelist)
        {
            StringBuilder strb = new StringBuilder();

            foreach(string s in fixturelist)
            {
                strb.Append(s + "\r\n");
            }
            textBox1.Text = strb.ToString();
        }
