在Windows窗体中切换语句 [英] Switch statement in windows forms

问题描述

Hello

我正在使用switch语句创建一个窗体。但它不起作用。谁能帮我？目的是计算一个人的理想体重和 一个女人，男人理想体重的公式是:(长度 - 100）/ 1,1。
的公式是女人的理想体重:(长+ 4 *手腕围 - 100）/ 2.

I was making a windows forms with a switch statement. But it don't work. Can anyone help me? The intention is to calculate the ideal weigth of a man and  a woman, the formula for the ideal weight of the man is: (length - 100) / 1,1. The formula for the ideal weight of the woman is: (length + 4 * wrist circumference - 100)/2.

这是我的代码。

                            

                           

            private void btnIdeaalGewicht_Click（object sender，EventArgs e）

        {

           串性;

           双倍长度，重量，WristCircumference，idealweightman，idealweightwoman;



            sex = txtsex.Text;

            length = Convert.ToDouble（txtlength.Text）;

            weight = Convert.ToDouble（txtweight.Text）;

            WristCircumference  = Convert.ToDouble（txtpolsWristCircumference.Text）;

            idealweightman = length - 100 / 1.1;

            idealweightwoman =（长度+（4 * WristCircumference） - 100）/ 2;



           开关（Convert.ToDouble（性别））

            {

               案例1：

                case（sex =="man"）：

                    MessageBox.Show（"你的理想体重是+ + idealweightman +"。""，"理想体重"，MessageBoxButtons.OK）;

                   休息;



            }¥b $ b        }¥b $ b    }
}

            private void btnIdeaalGewicht_Click(object sender, EventArgs e)
        {
            string sex;
            double length, weight, WristCircumference, idealweightman, idealweightwoman;

            sex = txtsex.Text;
            length = Convert.ToDouble(txtlength.Text);
            weight = Convert.ToDouble(txtweight.Text);
            WristCircumference  = Convert.ToDouble(txtpolsWristCircumference.Text);
            idealweightman = length - 100 / 1.1;
            idealweightwoman = (length + (4 * WristCircumference) - 100) / 2;

            switch (Convert.ToDouble(sex))
            {
                case 1:
                case (sex == "man"):
                    MessageBox.Show("Your ideal weight is " + idealweightman + ".", "Ideal weight", MessageBoxButtons.OK);
                    break;

            }
        }
    }
}

推荐答案

当出现这样的问题时，我建议在代码中设置一个断点，例如在line sex = txtsex.Text上，当您通过代码点击断点步骤时，检查值和代码流。这会导致逻辑无效或误解为
逻辑。 

When there are issues such as this I suggest setting a break-point in your code, e.g. on the line sex = txtsex.Text, when you hit the break-point step thru the code, examine values and flow of code. This will lead you to invalid logic or misinterpreted logic.
