Question

我在显示文本框中计算的平均值和数字时出现问题..当我点击显示按钮时它只返回0 0值，我认为问题出在我的字符串阅读器中，但我不知道我在哪里出错了我的代码

  //initialising the array
            int numbers = counts;
            Array.Resize(ref scoreArray, numbers);

            //outputting and displaying the count in a text box
            for (int count = 1; count > numbers; count++)
            {
                scoreArray[count] = scores;
                txtCount.Text = count.ToString();
            }
        }

        //catch statement for displaying error message
        catch (Exception)
        {
            MessageBox.Show(" Please enter valid number ");
        }
    }

    private void btnDisplay_Click(object sender, EventArgs e)
    {

        string toDisplay = string.Join(Environment.NewLine, scoreArray);
        MessageBox.Show(toDisplay);

        txtNumScores.Focus();
        txtCount.Clear();
        txtAverage.Clear();
        txtNumScores.Clear();
        txtTotal.Clear();
        counts = 0;
        total = 0;
    }

    private void btnClear_Click(object sender, EventArgs e)

Answer 1

更改

for (int count = 1; count > numbers; count++)
            {
                scoreArray[count] = scores;
                txtCount.Text = count.ToString();
            }

到

for (int count = 1; count < numbers; count++)
            {
                scoreArray[count] = scores;
                txtCount.Text = count.ToString();
            }

Answer 2

似乎你的整个for循环取决于int numbers = count;的初始值以及之后 btnDisplay_Click中的count = 0;所以number = 0;因此你的for循环似乎根本没有执行，所以，你应该交叉验证上面@Jorge指出的for循环条件。
