Question

我使用C＃中的List创建了动态文本框，我希望在创建文本框后立即执行事件

以下是我的代码。

    private List<TextBox> txtTotalCost = new List<TextBox>();

    private void btnMaterialAdd_Click(object sender, EventArgs e)
    {
        TextBox tbTotalCost = new TextBox();
        tbTotalCost.Location = new Point(652, RowCount * 22);
        tbTotalCost.Width = 60;
        txtTotalCost.Add(tbTotalCost);
        tbTotalCost.MouseClick += tbTotalCost_TextChanged;
        panel1.Controls.Add(tbTotalCost);
     }

    void tbTotalCost_TextChanged(object sender, EventArgs e)       
    {
        TextBox tb = (TextBox)sender;
        TotalCost = CanadianCost * Qut;
        tb.Text = TotalCost.ToString();
        return;
    }

我想生成或执行事件作为创建的文本框我现在想要鼠标单击或text_change。并希望在

中显示两个整数的乘法

我该怎么办？

这样做：

private void btnMaterialAdd_Click(object sender, EventArgs e)
{
    TextBox tbTotalCost = new TextBox();
    tbTotalCost.Location = new Point(652, RowCount * 22);
    tbTotalCost.Width = 60;
    txtTotalCost.Add(tbTotalCost);
    tbTotalCost.MouseClick += tbTotalCost_TextChanged;
    panel1.Controls.Add(tbTotalCost);
    tbTotalCost_TextChanged(tbTotalCost, null);  // <-- this line.
 }

如何在创建文本框时立即在c＃中对动态生成的文本框执行事件
