从复选框中显示的值构建数组？ [英] Building an array from a values displayed in checkboxes?

问题描述

大家好，

我是编程的初学者，我正在构建一个简单的程序，用户可以从中订购冷冻酸奶。该程序具有容器，浇头，香料等类型，并且将产生"收据"。所选的所有内容及其价格，点击"订购"后
。

我目前有许多复选框列出每个配料，分组在一个集装箱框中。我想要它，以便用户选择的每一个顶部，它最终将作为收据的一部分在屏幕上列出。我应该怎么做呢？如果我错误的是
，我应该从这些复选框中构建一个数组，然后使用"for循环"以某种方式显示该数组？

有人可以给出我知道我应该从哪里开始，或者如何制作我想要的东西？

谢谢，

贾斯汀

解决方案

您好Justim13601，

您说要添加许多复选框在GroupBox中控制，并循环GroupBox并将复选框复选到数组中，对不对？如果是，您可以查看以下代码：

我在表单中添加一个GroupBox和八个复选框。

私人清单< CheckBox> list = new List< CheckBox>（）; 
 private void button2_Click（object sender，EventArgs e）
 {
 foreach（checkBox c in groupBox1.Controls）
 {
 if（c.Checked == true） 
 {
 list.Add（c）; 
} 
} 
 
 for（Int32 i = 0; i< list.Count; i ++）
 {
 Console.WriteLine（" {检查0}，文本为{1}"，list [i] .Name，list [i] .Text）; 
} 
} 

最好的问候，

Cherry

Hi all,

I'm a beginner in programming and am just building a simple program where the user can order frozen yogurt from. The program has types of containers, toppings, flavours, etc., and would generate a "receipt" of everything selected, and their price, upon clicking "order".

I currently have many checkboxes listing each toppings, grouped in a group container box. I want it so that for every topping the user selects, it will eventually list it on the screen as part of a receipt. How should I go about doing that? If I'm not mistaken, I should build an array from those checkboxes, and then display that array somehow with the use of "for loops"?

Can someone give me an idea of where I should start or how I can make what I want happen?

Thanks,

Justin

Hi Justim13601,

You said that you want to add many checkbox controls in GroupBox, and loop GroupBox and get the checked checkbox into array, am I right? If yes, you can take a look the following code:

I add one GroupBox and eight checkbox in the Form.

  private List<CheckBox> list=new List<CheckBox>();
        private void button2_Click(object sender, EventArgs e)
        {
            foreach(CheckBox c in groupBox1.Controls)
            {
                if(c.Checked==true)
                {
                    list.Add(c);
                }
            }

            for(Int32 i=0;i<list.Count;i++)
            {
                Console.WriteLine("The {0} is checked and text is {1}",list[i].Name,list[i].Text);
            }
        }

Best Regards,
