combox如何添加带Value和Text的item

初学winform的时候，一直以为winform中的combox只能添加简单的仅有text的item,而不象aspx中的listitem那样即有text，又有value，结果很快发现自己错了，以下是一个示例:

先声明一个类

    public class ClsItemObject
    {
        public string ClassName = "", ClassId = "";

        public ClsItemObject(string _clsName, string _clsId) 
        {
            ClassName = _clsName;
            ClassId = _clsId;
        }

        public override string ToString()
        {
            return ClassName;
        }
    }

 

利用这个类，我们可以直接在combox中添加复杂类型的item

ClsItemObject[] co = new ClsItemObject[3];
            co[0] = new ClsItemObject("精美礼品", "001");
            co[1] = new ClsItemObject("--手工礼品", "002");
            co[2] = new ClsItemObject("家用电器", "333");
            comboBox1.Items.AddRange(co);
            comboBox1.SelectedIndex = 1;

取值时，要记得用强制类型转换，转换成正确的类型

 ClsItemObject coSelected = (ClsItemObject)comboBox1.SelectedItem;
            MessageBox.Show(coSelected.ClassId);

使用一例：

public class StringIntObject
        {
            public string Text;
            public int Value;

            public StringIntObject(string text, int value)
            {
                Text = text;
                Value = value;
            }

            public override string ToString()
            {
                return Text;
            }
        }

        public void RefreshHubGroup()
        {
            this.comboBox3.Items.Clear();
            CLocalTabStruct.SHubGroupParam[] records = null;
            CAccessLayer.GetHubGroupParam(out records);
            if (records == null)
                return;

            StringIntObject[] so = new StringIntObject[records.Length];
            for (int i = 0; i < records.Length; i++)
                so[i] = new StringIntObject(records[i].GroupName, records[i].HGPId);
            this.comboBox3.Items.AddRange(so);
            this.comboBox3.SelectedIndex = 0;
        }
