Question on array and methods

public static void Main(string[] args)

    //change the number of arrays to 10!
    string[] studentNames = new string[3];
    int[] finalScores = new int[3];

    int minIndex, minGoes, temp;

    for (int i = 0; i < studentNames.Length; i++)
    {
        Console.Write("Enter student name " + ": ");
        studentNames[i] = Convert.ToString(Console.ReadLine());
        Console.Write("Enter student score " + ": ");
        finalScores[i] = Convert.ToInt32(Console.ReadLine());
    }

    minGoes = 0;
    minIndex = 0;

    for (int j = 1; j < finalScores.Length; j++)
    {
        if (finalScores[j] > finalScores[minIndex])
        {
            minIndex = j;
        }
        temp = finalScores[minIndex];
