如何在winforms中将Dictionary绑定到ListBox

Question

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？

Answer 1

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解脱出来:将ComboBox绑定到通用词典.)

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