Question

真的很愚蠢的问题因为我认为你不能这样做但

 namespace Parking_Ticket_Fines
 {
   public partial class frmParking : Form
   {
    public frmParking()
    {
        InitializeComponent();
    }

    private void btnCal_Click(object sender, EventArgs e)
    {
        //Variable
        int Total = 0;

        //Checks which radio button is checked
        if (radExpired.Checked)
        {
            Total = 35;
        }
        else if (radParking.Checked)
        {
            Total = 75;
        }
        else if (radDriveway.Checked)
        {
            Total = 150;
        }
        else if (radHandicap.Checked)
        {
            Total = 500;
        }
    }

    private void btnClear_Click(object sender, EventArgs e)
    {
        //Clears everything 
        lblTotal.Text = "";
        radRepeat.Checked = false;
        radExpired.Checked = true;
    }

有没有办法可以在两个私有空间中使用“Total”变量而不会两次声明它？

Answer 1

有没有办法可以在两个私人空间中使用“总计”变量没有两次宣布它？

是在班级宣布。

public partial class frmParking : Form
   {
    private int Total; //Here 
    public frmParking()
    {
        InitializeComponent();
    }

此Total字段会更多地显示Fields (C# Programming Guide)

声明范围C＃之外的变量
