about C# write in “window form”

Question

Hello guys
I meet a question here.
Write the C# code for the bellow condition :

An array of raw scores for 10 students without user input
In the array, the first student is No. 1, and so on.
The topic will explain, for example:
Student No. 3 spoke twice.
Add 2 points for each speech, calculate the score after the score

Answer 1

Now I can only write like:

private void button1_Click(object sender, EventArgs e)
{

int Read;
int[] Value = new int[] { 10, 30, 50, 70, 90 };
for (int index = 0; index < 5; index++)
{
Read = Value[index];
}

int[] Score = new int[] { 10, 30, 50, 70, 90 };
String Result = "score1:" + Score[0].ToString() + " score2:" + Score[1].ToString();
MessageBox.Show(Result);
}

But the middle process is still incomplete…………
