我们先来看下运行效果图

Form1.cs代码:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Collections;
namespace MoveItem
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
ArrayList list = new ArrayList();
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void Form1_Load(object sender, EventArgs e)
{
for (int i = 1; i <= 10; i++)
{
list.Add(i);
string s = i.ToString();
listBox1.Items.Add(s);
}
}
private void listBox2_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
//单选,无法实现多选
//string str = this.listBox1.Text.Trim().ToString();
//if (listBox1.Items.Contains(str))
//{
//  listBox1.Items.Remove(str);
//  listBox2.Items.Add(str);
//}
for (int i=0;i<listBox1.SelectedIndices.Count;i++)
{
listBox2.Items.Add(listBox1.Items[listBox1.SelectedIndices[i]]);
listBox1.Items.RemoveAt(listBox1.SelectedIndices[i]);
i--;
}
}
private void button2_Click(object sender, EventArgs e)
{
for (int i = 0; i < listBox2.SelectedIndices.Count; i++)
{
listBox1.Items.Add(listBox2.Items[listBox2.SelectedIndices[i]]);
listBox2.Items.RemoveAt(listBox2.SelectedIndices[i]);
i--;
}
}
private void button3_Click(object sender, EventArgs e)
{
listBox2.Items.AddRange(listBox1.Items);
listBox1.Items.Clear();
}
private void button4_Click(object sender, EventArgs e)
{
listBox1.Items.AddRange(listBox2.Items);
listBox2.Items.Clear();
}
}
}
