public class Item { public string key; public string value; } 此时不能直接将List<Item>绑定到ComboBox cob.DataSource = items.itemCollection; cob.DisplayMember = "Value"; cob.ValueMember = "Key"; 必须将Item类修改为 public class Item { private string key; public string Key { get { return key; } set { key = value; } } private string value; public string Value { get { return this.value; } set { this.value = value; } } }CodeBye 版权所有丨如未注明 , 均为原创丨本网站采用BY-NC-SA协议进行授权 , 转载请注明List集合绑定到ComboBox！
