首先在工程下建立一个名为comboBox的类，类中内容如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace comboBox控?件t测a试º?
{
class ComboxItem
{
privatestring _RealValue = "";
privatestring _DisplayText = "";
public string DisplayText
{
get
{
return_DisplayText;
}
}
public string RealValue
{
get
{
return_RealValue;
}
}
publicComboxItem(string ShowText, string RealVal)
{
_DisplayText = ShowText;
_RealValue = RealVal;
}
public override stringToString()
{
return_RealValue.ToString();
}
}
}
然后，
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Collections;
namespace comboBox控件测试
{
public partial class Form1 : Form
{
publicForm1()
{
InitializeComponent();
}
privatestatic DataSetds = new DataSet();
privatevoid button1_Click(objectsender, EventArgs e)
{
MessageBox.Show(comboBox1.SelectedValue.ToString());
}
privatevoid Form1_Load(objectsender, EventArgs e)
{
ArrayListal = new ArrayList();
al.Add(newComboxItem("男", "1"));
al.Add(new ComboxItem("女", "0"));
comboBox1.DataSource = al;
comboBox1.DisplayMember = "DisplayText";
comboBox1.ValueMember = "RealValue";
}
}
}
