问题描述
我正在使用 WinForms 中的 ListBox 编写 C# 应用程序.
I'm writing a C# app using a ListBox in WinForms.
我从一个 XML 文件中获取我的数据(ID 和全名).我想在列表框中显示全名，当我选择其中一个时，我想获取相关的 id.
I get my data (id and full name) from an XML file. I want to show full names in the listbox and when I select one of them, I want to get the relevant id.
我尝试使用 SelectedValue 属性，但没有成功.
I tried using SelectedValue property with no luck.
我也试过 KeyValuePair，它在列表框中显示[full name, id]"，这不是我想要的:
I also tried KeyValuePair and it shows "[full name, id]" in the listbox, which is not what I wanted:
LB_UserList.Items.Add(new KeyValuePair<string, string>(full_name, node["user_id"].InnerText));
简而言之，如何在 C# 中模拟 HTML 选择?我想在列表框中显示全名并在后端获取相关 id.
How can I simulate a HTML select in C# in short? I want to show full names in the listbox and to get relevant id in the backend.
推荐答案
使用c# 字典为此，
Dictionary<string, string> list = new Dictionary<string, string>();
list.Add("item 1", "Item 1");
list.Add("item 2", "Item 2");
list.Add("item 3", "Item 3");
list.Add("item 4", "Item 4");
dropdown.DataSource = list;
dropdown.DataTextField = "Value";
dropdown.DataValueField = "Key";
dropdown.DataBind();
<小时>
listBox.DataSource = new BindingSource(list, null);
listBox.ValueMember = "Key";
listBox.DisplayMember = "Value";
