从动态创建的复选框获取文本值 [英] Getting Text Value from a dynamically created checkbox

问题描述

大家好，


这是我的代码:

Hello guys,


Here is my code:

CheckBox[] cb = new CheckBox[100];
for (int i = 1; r2.Read(); i++)
            {
                int height = 1;
                    cb[i] = new CheckBox();
                    cb[i].Name = i.ToString();
                    cb[i].Text = r2[1].ToString();
                    cb[i].Location = new Point(30, i * 30);
                    this.Controls.Add(cb[i]);
                    height += 22;
            }

推荐答案

有一些问题:

1.数组索引从0开始，而不是1

2.您不检查数组是否溢出，如果for循环超过100次迭代该怎么办?

3.高度用作什么?它在for块中是本地的，不用于任何用途

4.定义选择"?您可以使复选框处于焦点状态，但是当您单击按钮时，该复选框将失去焦点.因此，可以这么说，那时没有选定"复选框.

There are a few issues there:

1. The array index starts at 0, not 1

2. You don''t check for array overflow, what if the for loop crosses 100 iterations?

3. What''s height used for? It''s local to the for block and not used for anything

4. Define "selected"? You can have a checkbox in focus, but the moment you click on the button the checkbox loses focus. So at that time there is no "selected" checkbox, so to speak.

为什么不使用Listbox代替呢?您可以打开复选框，选择一个项目时，只需获取该项目的文本即可.除此之外，它看起来比在窗体上具有100个单独的列表框要好得多.

Why don''t you use a Listbox instead? You can turn on checkboxes, and when you select an item, just get the item''s text. Beyond that, it will look a lot better than having 100 individual listboxes on a form.

另一种方法是使用CheckedListBox:
