骰子程序C#.net使用数组

我的程序需要一些帮助，我构建了一个简单的骰子程序来显示100次掷骰子的两个骰子之和的频率。程序将读取该文件。

现在，我需要声明一个数组，该数组表示两个骰子投掷的可能结果。对于文件中的每个条目，递增与该结果对应的数组元素。最后，显示该模拟的频率计数。我不知道如何在程序中使用数组，需要帮助将其实现到程序中。

namespace Dice_Program
{
    public partial class RollDice : Form
    {
       private int Dice1;
       private int Dice2;
       private int SUM;
       const int Roll_MAX = 100;
       private void btn_roll_Click(object sender, EventArgs e)
       {
           Random rand = new Random();
           for (int lineNum = 1; lineNum <= Roll_MAX; lineNum++)
           {
               Dice1 = rand.Next(6) + 1;
               Dice2 = rand.Next(6) + 1;
               SUM = Dice1 + Dice2;
               lstboxtotal.Items.Add(" On roll. "  + lineNum +  " You rolled a, "  + Dice1 + " and a "  + Dice2 +  " for a sum of " + SUM);
           }
       }
        private void btnwrite_Click(object sender, EventArgs e)
        {    // Create a StreamWriter object 
            StreamWriter rollLog; 
            rollLog = File.CreateText ("Roll Results.txt"); // Creating the file
            for (int count = 0; count <lstboxtotal.Items.Count; count++)
            {
                rollLog.WriteLine(Convert.ToString(lstboxtotal.Items[count]));
            }
            rollLog.Close(); // close file after creation 
            MessageBox.Show ("Your results have been successfully Saved to file.");
        } // only first line is written 100 times
        private void btnread_Click(object sender, EventArgs e)
        {
            using (StreamReader rollLog = new StreamReader("Roll Results.txt"))
            {
                while (rollLog.Peek() >= 0)
                {
                    lstboxtotal.Items.Add(rollLog.ReadLine());
                }
            }
        }
    }
}

我理解你的英语有点困难。但我认为你想要这样的东西。

（*请注意，这是一种伪代码，不会立即编译，但我不会做你的功课）

int[] Rolls = { 0, 0, 0, 0, 0, 0 }; // 1 dice = 6 possible rolls 1- 6

void RollDice() {
    int randomRoll = GetRandomDiceRoll(); //assume this returns 1-6 for the roll
    //We use randomRoll-1 becuase the array is zero-indexed E.g. 0-5
    Rolls[randomRoll-1]++;
    //This increments the value and if the roll was 3 for instance your array will look like
    // { 0, 0, 1, 0, 0, 0 }
}
