Thread: need help for reading two keyboard inputs

I have the following code and was wandering if someone could help me in telling me how i could make the program read 2 inputs such as: 87 and 68 ('w' and 'd') instead of reading just one input at a time. In otherwords.. how could i get into the: if (check == 68) code area.

Code:

        private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            int num = e.KeyValue;
            string w = Convert.ToString(num);
            label1.Text = w;
            switch (num)
            {
                case 87:
                    while (num == 87)
                    {
                        label4.Text = "check 1";
                        int check = e.KeyValue;

                        if (check == 68)
                        {
                            label4.Text = "Works";
                        }
                        else
                        {
                            break;
                        }
                    }
            }
        }
