C# WinForm ListBox 可多选的默认值如何设置？

[lqflsh]

C# WinForm ListBox控件Selection属性为MultiExtended

//数据绑定代码
DT = ODA.SelectCommand().Tables[0];
listBox1.DataSource = DT;
listBox1.DisplayMember = "xm"; //显示值得字段名称
listBox1.ValueMember = "id"; //绑定值的字段名称

比如现在想把id=2,3,5的值默认被选中该怎么做？

好像没什么好的办法，只能循环检测了。
WPF应该可以把属性捆定到item的property上去。

            List<Person> people = new List<Person>();
            people.Add(new Person { Age = 25, FirstName = "Alex", LastName = "Johnson" });
            people.Add(new Person { Age = 23, FirstName = "Jack", LastName = "Jones" });
            people.Add(new Person { Age = 35, FirstName = "Mike", LastName = "Williams" });
            people.Add(new Person { Age = 25, FirstName = "Gill", LastName = "JAckson" });
            this.listBox1.DataSource = people;
            this.listBox1.DisplayMember = "FirstName";
            this.listBox1.ValueMember = "Age";

            for (int i = 0; i < listBox1.Items.Count; ++i)
            {
                if (((Person)listBox1.Items[i]).Age == 25)
                    listBox1.SetSelected(i, true);
            }
