如何绑定到词典列表框的WinForms中 [英] How to bind Dictionary to ListBox in winforms

问题描述

这是可能的词典绑定到一个列表框，在保持同步列表框和成员属性之间？

解决方案

  VAR的选择=新词典＆LT;字符串，字符串＆GT;（）;
选择[A] =亚瑟
选择[F] =福特;
选择[T] =Trillian的;
选择[Z] =赞福德;
listBox1.DataSource =新的BindingSource（选择，NULL）;
listBox1.DisplayMember =值;
listBox1.ValueMember =键;
 

（无耻地从我自己的博客解禁：绑定一个ComboBox通用字典。）

这意味着你可以使用的SelectedValue来获得相应的字典键搁置ListBox中选定的项目。

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

解决方案

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";

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

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