VB.Net Combobox 显示引用值的文本 [英] VB.Net Combobox to display text which refers to a value

问题描述

我想在组合框中显示多个项目，当用户选择时，将返回引用该文本的特定值而不是返回文本.对此的任何帮助将不胜感激.

I would like to display a number of items in a combobox and when the user selects on, instead of the text being returned a specific value referring to that text is returned. Any help with this would be much appreciated.

推荐答案

这是典型的 Key,Value 绑定.我将使用 Dictionary 作为示例.因此，假设您已经用正确的值填充了 Dictionary，代码可能如下所示:

This is a typical Key,Value binding. I will use a Dictionary, as an example. So assuming you have populated your Dictionary with proper values, the code can look like this:

ComboBox1.DataSource = yourDictionary.ToList
ComboBox1.DisplayMember = "Value"
ComboBox1.ValueMember = "Key"

然后您可以使用 ComboBox1.SelectedValue 属性选择值.

You can then pick the value using ComboBox1.SelectedValue property.
