Hi, how can I optimize my code? Reduce the number of lines(Statements)

private void button1_Click(object sender, EventArgs e)

{

string[] seq1 = { "A", "C", "G", "T", "A", "C", "A", "G","T","G" };

string[] seq2 = { "T", "A", "C", "A", "C", "G","A","A","G","T" };

string[] res1 = new string[seq1.Length];

string[] res2 = new string[seq1.Length];

for (int i = 0; i <= 4; i++)

{

res1[i] = seq1[i];

res2[i] = seq2[i];

textBox1.Text +=" "+ res1[i];

textBox2.Text +=" "+ res2[i];

}

for(int i = 5; i < seq1.Length; i++)

{

if (seq1[i] == "T" )

{

res1[i] = "A";

}

else

if (seq1[i] == "A" )

{

res1[i] = "T";

}

else

if (seq1[i] == "C" )

{

res1[i] = "G";

}

else

if (seq1[i] == "G" )

{

res1[i] = "C";

}

textBox1.Text += res1[i]+" ";

}

for (int i = 5; i < seq2.Length; i++)

{

if (seq2[i] == "T")

{

res2[i] = "A";

}

else

if (seq2[i] == "A")

{

res2[i] = "T";

}

else

if (seq2[i] == "C")

{

res2[i] = "G";

}

else

if (seq2[i] == "G")

{

res2[i] = "C";

}

textBox2.Text += res2[i] + " ";

}

I have attached source code file, take a look and tell us if it solves your problem. But i'm still not getting your point of view.

Test out this code and see if that fits into your program. Key is to use the Stringbuilder instead of string to reduce the time.
string[] seq1 = { "A", "C", "G", "T", "A", "C", "A", "G", "T", "G" };
            string[] seq2 = { "T", "A", "C", "A", "C", "G", "A", "A", "G", "T" };
            string[] res1 = new string[seq1.Length];
            string[] res2 = new string[seq1.Length];
            StringBuilder[] arrStrings = new StringBuilder[2];
            arrStrings[0] = new StringBuilder(string.Join(null, seq1));
            arrStrings[1] = new StringBuilder(string.Join(null, seq2));
            for (int j = 0; j < arrStrings.Length; j++)
            for (int i = 5; i < arrStrings[j].Length; i++)
            {
                switch (arrStrings[j][i])
                {
                    case 'T':
                        arrStrings[j][i] = 'A';

                        break;
                    case 'A':
                        arrStrings[j][i] = 'T';
                        break;
                    case 'C':
                        arrStrings[j][i] = 'G';
                        break;
                    case 'G':
                        arrStrings[j][i] = 'C';
                        break;
                    default:
                        break;
                }

            }
            textBox1.Text = arrStrings[0].ToString();
            textBox2.Text = arrStrings[1].ToString();
