从 Windows 窗体中选择所有文本框并向每个文本框添加特定文本?

问题描述

我有一个带有 6 个 TextBoxes(txtNumber1、txtNumber2、...)的 WinForm.当我单击按钮时，我生成 6 个随机数并将它们添加到 ArrayList，然后我想在每个 TextBox 中放入这些数字中的 1 个.>

我可以通过执行 txtNumber1.Text = arraylist[0]; 等等...

我想知道是否有一种方法可以像在 JavaScript 中使用 for 循环那样执行此操作，只需更改 TextBox id 的编号并避免将数字一一相加.

解决方案

试试这个:

int i = 0;foreach(Controls.OfType()中的TextBox控件){(control).Text = arraylist[i].ToString();我++;}

这将遍历表单的所有TextBoxes，并将它们的文本设置为ArrayList 的值.当然，TextBoxes 的数量和 ArrayList 的长度应该相同，那么这段代码应该适合你.

I have a WinForm with 6 TextBoxes (txtNumber1, txtNumber2, ...). When I click the button, I generate 6 random numbers and add they to a ArrayList, and then I want to put 1 of these numbers in each of the TextBox.

I can do this by doing txtNumber1.Text = arraylist[0]; and so on...

I wonder if there is a way I can do this like I would do with JavaScript using a for loop, just changing the number of the TextBox id and avoid having to add the numbers one by one.

解决方案

Try this:

int i = 0;
foreach (TextBox control in Controls.OfType<TextBox>())
{
     (control).Text = arraylist[i].ToString();
     i++;
}

This iterate through all TextBoxes of the form and set their texts to ArrayList's values. Of course the count of the TextBoxes and the ArrayList's length should be same then this code should works fine for you.
