用于将多个单个复选框控件文本插入到数据库中的单个列中的循环

Question

我需要将多个复选框文本插入到 mssql 数据库的列中， 我可以使用单个复选框列表并使这件事变得更容易，但是， 要求是显示带有多个复选框的单独的 html 行和列， 有点像检查应用设计的所有条件，但是对于几个标准，所以我猜测字符串生成器或数组可能会这样做，所以我正在尝试以下代码，但必须有一个比为每个复选框手动执行此操作更好的更干净的方法？

请帮助我的代码如下：

asp.net page

Answer 1

您需要将复选框放入某种容器中，例如面板或占位符，然后您可以执行以下操作：

ASPX：

<asp:Panel ID="Panel1" runat="server">
    <asp:CheckBox ID="chk1" runat="server" Text="..." />
    ...
</asp:Panel>

ASP.NET 3.5 及更高版本的代码隐藏：

foreach (CheckBox chk in Panel1.Controls.OfType<CheckBox>())
{
    if (chk.Checked)
    {
        //update parameter
        cmd.Parameters["@eventCriteria"].Value += String.Format("{0},", chk.Text);
    }
}

//you'll probably need to trim the trailing comma too
cmd.Parameters["@eventCriteria"].Value = cmd.Parameters["@eventCriteria"].Value.TrimEnd(',');

ASP.NET 2.0 及更早版本的代码隐藏：

foreach (Control ctrl in Panel1.Controls)
{
    if (ctrl is CheckBox)
    {
        CheckBox chk = (CheckBox)ctrl;
        if (chk.Checked)
        {
            //update parameter
            cmd.Parameters["@eventCriteria"].Value += String.Format("{0},", chk.Text);
        }
    }
}

//you'll probably need to trim the trailing comma too
cmd.Parameters["@eventCriteria"].Value = cmd.Parameters["@eventCriteria"].Value.TrimEnd(',');

Answer 2

您可以使用 Request.Form 并利用 CheckBox id

foreach(string key in Request.Form) {
    if (!key.StartsWith("eventCriteria")) continue;
    //database insert logic

}
