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:Bind一个 ComboBox 到一个通用字典.)

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

这意味着您可以使用 SelectedValue 来获取列表框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.
