Question

public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();            List list = new List();            list.Add(new Source            {                ID = "1",                Name = "kobe"            });            list.Add(new Source            {                ID = "2",                Name = "JORDAN"            });            this.comboBox1.DisplayMember = "Name";            this.comboBox1.ValueMember = "ID";            this.comboBox1.DataSource = list;             this.comboBox2.DisplayMember = "Name";            this.comboBox2.ValueMember = "ID";            this.comboBox2.DataSource = list;        }    }    public class Source    {        public string ID { get; set; }        public string Name { get; set; }    } （选择后）为什么combox1变化后。。combox2跟着变化？？？？高手请教！！！...

Answer 1

应该是你的2个combox共用了一个list, 然后你改变了list，然后2个就都变化了

Answer 2

因为你共用了一个变量list，  this.comboBox1.DataSource = list;改成  this.comboBox1.DataSource = list.ToList();

Answer 3

下拉选中事件。。跟list有什么关系???

Answer 4

list相当于c++中的指针，内存用的是一个，所以你改变了选中的值，那就相当于当前指针指向地址变化了，所以第二个显示也会变化

Answer 5

哥，我一直关注你这个问题，咋就这么草率的结贴了
