增加文本框名称中的数字

Question

public void test()
    {
        List<int> list = new List<int>();
        list.Add(1);
        list.Add(2);
        list.Add(3);
        for (int i = 1; i <= list.Count; i++)
        {

            textBx.Text = list[i].ToString();
            // I want it to be textBx1.Text = list[1].ToString();
                               textBx2.Text = list[2].ToString();
                               textBx3.Text = list[3].Tostring();
                               etc.
              // I can't create textbox dynamically as I need the text box to be placed in specific places in the form . How do I do it the best way?

听起来像是Controls.Find()的工作.您可以动态构建字符串并使用该名称搜索TextBox:

 var textBox = this.Controls.Find("textBx" + i, true) as TextBox;
 textBox.Text = list[i].ToString();

这有点难看,因为它取决于TextBoxes的命名约定.也许更好的解决方案是在循环之前缓存TextBox的列表:

var textBoxes = new[] { textBx1, textBx2, textBx3 };

然后你可以简单地索引到数组:

textBoxes[i].Text = list[i].ToString();
