这是我的代码（在Form2_Load中）

Here are my codes (in Form2_Load)

 for (i=0;i<AnaEkranForm.n1;i++)
            {
                
                GroupBox gBKisaMetin = new GroupBox();
                this.Controls.Add(gBKisaMetin);
                gBKisaMetin.Location = new Point(80, gYuksek);
                gYuksek += 200;
                gBKisaMetin.Text = "Soru " + (soruSayac++);
                gBKisaMetin.Width=500;
                
                gBKisaMetin.Height = 150;
                
                TextBox tBSoru = new TextBox();
                tBSoru.Location = new Point(30, 30);
                tBSoru.Width = 400;
                gBKisaMetin.Controls.Add(tBSoru);

                Label labelCevap = new Label();
                labelCevap.Location = new Point(30, 70);
                labelCevap.Text = "Cevap";
                gBKisaMetin.Controls.Add(labelCevap);

                TextBox tBKisaMetinCevap = new TextBox();
                tBKisaMetinCevap.Location = new Point(30, 95);
                tBKisaMetinCevap.Width = 400;
                
                gBKisaMetin.Controls.Add(tBKisaMetinCevap);
                tBKisaMetinCevap.ReadOnly = true;

                Button btnSil = new Button();
                btnSil.Location = new Point(460, 10);
                btnSil.Width = 30;
                btnSil.Text = "Sil";
                btnSil.Name = "btnSil_" + i.ToString();
                btnSil.Click += new EventHandler(btnSil_Click);
                
                gBKisaMetin.Controls.Add(btnSil);
}

 private void btnSil_Click(object sender, EventArgs e)
        {
           //The codes what i need should be in here 
        }

感谢您的帮助

推荐答案

为GroupBox添加一个名称，基于i.ToString（），就像你对按钮所做的那样（这样点击处理程序将知道要删除哪个GroupBox）。 />
将按钮的Tag属性设置为GroupBox，如下所示：

Add a name to your GroupBox, based on the i.ToString() like you did for the button (this is so the click handler will know which GroupBox to remove).
Set the button's Tag property to the GroupBox like this:

btnSil.Tag = gBKisaMetin;

然后，btnSil_Click中的代码应如下所示：

Then, the code in your btnSil_Click should look like this:

private void btnSil_Click(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    GroupBox gb = (GroupBox)btn.Tag;
    this.Controls.RemoveByKey(gb.Name);
}
