动态分配按钮文本通过循环 [英] Assign button text dynamically via a loop

问题描述

我试图通过使用如下的循环动态分配按钮控件文本：

  INT ButtonNumber = 1;而（ButtonNumber小于10）
{
    //什么事要做！？
    ButtonNumber ++;
}
 

我要避免以下内容：

  button1.Text =;
button2.Text =;
button3.Text =;
button4.Text =;
button5.Text =;
button6.Text =;
button7.Text =;
button8.Text =;
button9.Text =;
 

解决方案

理想的情况下，不具备按钮1 ，按钮2 等在首位的变量。有一个集合（如列表与LT按钮＆GT; ）

 私人列表＆LT;按钮和GT;按钮=新的List＆LT;按钮和GT;（）;
 

（编辑：你需要填充这个​​地方，当然...）

再后来更新文本：

 的for（int i = 0; I＆LT; buttons.Count;我++）
{
    按钮[i]。文本=我按钮+我;
}
 

这不与设计师发挥非常好听，很遗憾。

您的可以的获取由ID的控制，但我个人尽量不要做。如果你的真正的希望：

 的for（int i = 1; I＆LT; = 10;我++）
{
    控制控制=控件[键+ i];
    control.Text =我按钮+我;
}
 

I am trying to assign button controls text dynamically by using a loop like the following:

int ButtonNumber = 1;

while (ButtonNumber < 10)
{
    //WHAT TO DO HERE!?
    ButtonNumber++;
}

I wanna avoid the following:

button1.Text = "";
button2.Text = "";
button3.Text = "";
button4.Text = "";
button5.Text = "";
button6.Text = "";
button7.Text = "";
button8.Text = "";
button9.Text = "";

解决方案

Ideally, don't have button1, button2 etc as variables in the first place. Have a collection (e.g. a List<Button>):

private List<Button> buttons = new List<Button>();

(EDIT: You'd need to populate this somewhere, of course...)

then to update the text later:

for (int i = 0; i < buttons.Count; i++)
{
    buttons[i].Text = "I'm button " + i;
}

This doesn't play terribly nicely with the designer, unfortunately.

You can fetch a control by ID, but personally I try not to do that. If you really want to:

for (int i = 1; i <= 10; i++)
{
    Control control = Controls["button" + i];
    control.Text = "I'm button " + i;
}
