推荐答案

基本上将标签和文本框控件放置在表单上进行输入，然后在按钮单击事件中验证文本框值是double类型的，如果是，则计算.

Basically place labels and text box controls on the form for input then in a button click event validate the text box values are of type double and if so do your calculations.

using System;
using System.Windows.Forms;

namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            double balance;
            double interestRate;
            double targetBalance;

            if (double.TryParse(txtbalance.Text, out balance) && double.TryParse(txtAnnualInterest.Text, out interestRate) && double.TryParse(txtLeaveBalance.Text, out targetBalance))
            {
                // do calculations and show results e.g. in a MessageBox.
            }
        }
    }
}
