Question

首先，请记住，我是一名专业设计师和自学成才的开发人员。因此，缺乏对发展中部分的了解。

我使用.ascx和.ascx.cs背后的代码创建了一个表单。我已成功使用此表单一段时间，使用基本文本字段，验证并在提交后收到包含选择的电子邮件。我最近不得不在表单中添加多个复选框。我做了一些研究，并使用下面的代码。它在网站的前端工作得很好，但是当提交表单时，我只能在我的电子邮件中找到其中一个选项。如何在后面的代码中设置代码，以便在电子邮件中收到多个选项？

这是.ascx代码：

<asp:CheckBoxList ID="CheckBoxWebsolutions" runat="server" AutoPostBack="false" TextAlign="Right" >
<asp:ListItem Value="Website Design">Website Design</asp:ListItem>
<asp:ListItem Value="Content Management System">Content Management System</asp:ListItem>
<asp:ListItem Value="Web App Development">Web App Development</asp:ListItem>
<asp:ListItem Value="Web Hosting">Web Hosting</asp:ListItem>
</asp:CheckBoxList>

这是.ascx.cs文件：

sbFormResult.Append(this.FormatAsTableRow("Send me more info on your Web Solutions:", CheckBoxWebsolutions.Text.ToString()));
sbFormResult.Append(this.FormatAsTableRow("Send me more info on your Email & Communications 1:", CheckBoxCommunications1.Text.ToString()));
sbFormResult.Append(this.FormatAsTableRow("Send me more info on your Email & Communications 2:", CheckBoxCommunications2.Text.ToString()));
sbFormResult.Append(this.FormatAsTableRow("Send me more info on your SharePoint Services:", CheckBoxCollaboration.Text.ToString()));

以下是电子邮件回复：

Answer 1

如果您需要显示多个回复，可以使用此伪代码（抱歉，未经测试）：

Dim strSelectedWebSolutions as String = ""

For Each item as ListItem in CheckBoxWebsolutions.Items
    If item.Selected Then strSelectedWebSolutions = strSelectedWebSolutions & " " & item.Text
Next item

sbFormResult.Append(this.FormatAsTableRow("Send me more info on your Web Solutions:", strSelectedWebSolutions));

Answer 2

根据您的问题，您希望收集所选CheckBox的文本。

var sbFormResult = new StringBuilder();

// Join by comma
string webSolutions = string.Join(",",
    CheckBoxWebsolutions.Items.Cast<ListItem>()
        .Where(x => x.Selected)
        .Select(x => x.Text));

sbFormResult.Append(this.FormatAsTableRow(
    "Send me more info on your Web Solutions:", webSolutions));

ASP表单中的多个复选框
