C# 记分板-将分数添加到主记分板-不工作

我正在尝试将分数添加到当前分数，因此当我们打印输出时，我希望将较早的分数添加到+1，然后将其相加并打印新分数。这不起作用，我尝试了很多选择，我如何解决这个问题集？我得到的输出是1，与第一个结果后显示的输出相同

namespace scoreboard
{

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        public double regnut()
        {
            int score = 0;
            return score = score + 1;
        }
        private void button1_Click(object sender, EventArgs e)
        {

            string input = textBox1.Text;

            int score;
            count();




        }
        void count()
        {
            string iny = textBox1.Text;
            double score = 0;

            if (iny == "t")
            {
                score = score + 1;
                listBox1.Items.Add(score);
            }
            label1.Text = "Score: " + score;
        }


    }
}

这是因为您总是将

分数
初始化回零。您需要有一个变量来保存
分数的当前值。示例如下：

private int currentScore = 0; // holds you current Score value

void count()
{
    string iny = textBox1.Text;
    int score = currentScore; // sets initial value based from the current Score
    if (iny == "t")
    {
        score = score + 1; // increment value
        listBox1.Items.Add(score);
    }

    currentScore = score; // store the value in the variable
    label1.Text = "Score: " + currentScore.ToString();
}
