怎样按字母顺序(ABCDEF)动态添加控件
考试系统中题库设计时,我想动态添加选项,顺序按ABCDEF这样,点击一下按钮添加A(radiobutton),再点击添加B,如此依次添加。本人比较菜,求达人写一个方法
[解决办法]
private int idx = 0;
添加按钮_Click(sender, e)
{
RadioButton rb = new RadioButton();
rb.Name = "rb" + ('A' + idx).ToString();
rb.Text = ('A' + idx).ToString();
rb.Top = 100 + rb.Height * idx;
this.Controls.Add(rb);
}
[解决办法]
private void button1_Click(object sender, EventArgs e)
{
string[] radioButtonList = new string[] { "A", "B", "C", "D", "E", "F", "G" };
for (int i = 0; i < radioButtonList.Length; i++)
{
if (this.Controls[radioButtonList[i]] == null)
{
RadioButton radioButton = new RadioButton();
radioButton.Name = radioButtonList[i];
radioButton.Text = radioButtonList[i];
radioButton.Width = 50;
radioButton.Location = new Point(100, 100 + i * 20);
this.Controls.Add(radioButton);
break;
}
}
}
