计算输出不传输

2024-05-21 • 问答

我正在尝试将多个用户输入框输入添加在一起进行计算，然后将它们显示到标签框中。当我使用计算 btn 时，我不知道为什么。我的标签框刚好等于 0。我的 btnClear 也可以清除输入文本框。如果我改变 miscChargelbl.Text = miscCharge.ToString();到 miscChargelbl.Text = 1.ToString();它将杂项费用标签框显示为 1。但如果我将其保留为 0，则意味着它不会从 CalcMiscCharges() 中进行计算。我如何才能将正确的文本输出到空标签中。

    //*Variables*//
    private double dayCharge;
    private double mediCharge;
    private double surgCharge;
    private double labCharge;
    private double rehabCharge;
    private double daysStay;
    private double stayCharge;
    private double miscCharge;
    private double totalCharge;
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender,EventArgs e)
    {

    }

    private void btnExit_Click(object sender,EventArgs e)
    {
        this.Close();
    }

    private void btnCalc_Click(object sender,EventArgs e)
    {
        /*I Cant figure why this doesn't change the labels to the inputted text*/
        miscChargelbl.Text = miscCharge.ToString();
        stayChargelbl.Text = stayCharge.ToString();
        totalChargelbl.Text = totalCharge.ToString();
        
    }
    private void CalcStayCharges()
    {
        /*Calculate the days stayed price*/
        dayCharge = 350;
        daysStay = Double.Parse(daySpenttxt.Text);
        stayCharge = dayCharge * daysStay;
       
        
    }
    private void CalcMiscCharges() 
    {
        mediCharge = double.Parse(medicationtxt.Text);
        surgCharge = double.Parse(surgicaltxt.Text);
        labCharge = double.Parse(labfeetxt.Text);
        rehabCharge = double.Parse(rehabtxt.Text);

        miscCharge = mediCharge + surgCharge + labCharge + rehabCharge;
        
    }
    private void CalcTotalCharges()
    {
        /*Add stay charge with misc charge*/
        totalCharge = stayCharge + miscCharge;
    }

    private void btnClear_Click(object sender,EventArgs e)
    {

        rehabtxt.Text = String.Empty;
        daySpenttxt.Text = String.Empty;
    }
