Question

在Visual Studio中，我有一个ComboBox，我手动输入五个项目。（产品）另外TextBox我必须自动写出价格。

在数组中，我保存了这些产品和名称的价格：

string [] prodmas = new string[5];
prodmas[0] = "თევზი";
prodmas[1] = "პური";
prodmas[2] = "ყავა";
prodmas[3] = "შაქარი";
prodmas[4] = "წვენი";

double[] fasmas = new double[5];
fasmas[0] = 1.2;
fasmas[1] = 2;
fasmas[2] = 2.4;
fasmas[3] = 1.3;
fasmas[4] = 2.5;

当我在ComboBox中选择第1项时如何操作，TextBox必须显示第1项价格（1.2）;当我选择item3时TextBox必须显示第3项价格（2.4）

private void produqcia_SelectedIndexChanged(object sender, EventArgs e)
{
    .......
}

  FULL CODE


  string [] prodmas = new string[5];
        double[] fasmas = new double[5];


        void masivebi()
        {
            prodmas[0] = "თევზი";
            prodmas[1] = "პური";
            prodmas[2] = "ყავა";
            prodmas[3] = "შაქარი";
            prodmas[4] = "წვენი";

            fasmas[0] = 1.2;
            fasmas[1] = 2;
            fasmas[2] = 2.4;
            fasmas[3] = 1.3;
            fasmas[4] = 2.5;

        }




        private void produqcia_SelectedIndexChanged(object sender, EventArgs e)
        {

            int index = produqcia.SelectedIndex;
            fasi.Text = String.Format("The item {0} price {1}", index + 1, fasmas[index].ToString());
        }

        private void Form1_Load(object sender, EventArgs e)
        {

            produqcia.DataSource = prodmas;
        }


    }

Answer 1

在表单构造函数或其他地方：

comboBox1.DataSource = prodmas;

选择事件：

private void produqcia_SelectedIndexChanged(object sender, EventArgs e)
{
    int index = comboBox1.SelectedIndex;
    textBox1.Text = String.Format("The item {0} price {1}", index + 1, fasmas[index].ToString());
}

但这不是一个很好的方法，更好地创建包含两个值的对象并将其绑定到组合框。然后将所选项目投射到您的对象并获得所需的值。
