如何将字典绑定到winforms中的ListBox [英] How to bind Dictionary to ListBox in winforms

问题描述

可以将字典绑定到列表框，在列表框和成员属性之间保持同步？

It is possible to bind a dictionary to a listbox, keeping in sync between the listbox and the member property?

推荐答案

var choices = new Dictionary<string, string>(); 
choices["A"] = "Arthur"; 
choices["F"] = "Ford"; 
choices["T"] = "Trillian"; 
choices["Z"] = "Zaphod"; 
listBox1.DataSource = new BindingSource(choices, null); 
listBox1.DisplayMember = "Value"; 
listBox1.ValueMember = "Key"; 

（无耻地从我自己的博客中提取：将ComboBox绑定到通用字典。）

(Shamelessly lifted from my own blog: Bind a ComboBox to a generic Dictionary.)

这意味着您可以使用SelectedValue来获取ListBox中所选项目的相应字典键。

This means you can use SelectedValue to get hold of the corresponding dictionary key for the selected item in the ListBox.
