c#中checkbox怎么添加项

1）在Visual studio中新建一个WindowsApplication。在Form1上布置两个控件textBox1和button1，如下图

2）后台代码

using System

using System.Collections.Generic

using System.ComponentModel

using System.Data

using System.Drawing

using System.Linq

using System.Text

using System.Windows.Forms

namespace WindowsFormsApplication1

{

    public partial class Form1 : Form

    {

        // 定义一个checkbox

        CheckBox chkBox

        public Form1()

        {

            InitializeComponent()

        }

        // 点击button1

        private void button1_Click(object sender, EventArgs e)

        {

            // 如果chkBox已经加载，则退出

            if (chkBox != null) return

            // 如果textBox1没有内容输入则退出

            if(textBox1.Text.Trim()==string.Empty) return

            

            // 动态加载一个Checkbox

            chkBox = new CheckBox()

            chkBox.Left = 10

            chkBox.Top = 10

            

            // 将textBox1输入内容作为checkbox的提示

            chkBox.Text = textBox1.Text

            // 点击checkbox时的事件处理

            chkBox.Click += chkBox_Click

            this.Controls.Add(chkBox)

        }

        void chkBox_Click(object sender, EventArgs e)

        {

            if (chkBox.Checked)

            {

                MessageBox.Show(chkBox.Text + "被选中！")

            }

            else

            {

                MessageBox.Show(chkBox.Text + "没有选中！")

            }

        }

    }

}

#region[加入选择列]

DataGridViewCheckBoxColumn dgv1 = new DataGridViewCheckBoxColumn()

dgv1.Name = "选择"

dataGridView1.Columns.Insert(0, dgv1)

dataGridView1.MultiSelect = true

dgv1.InheritedStyle.Alignment = DataGridViewContentAlignment.TopCenter

dgv1.Width = 35

this.dataGridView1.VirtualMode = false

for (int i = 0i <this.dataGridView1.Columns.Counti++)

{

if (i == 0)

{

this.dataGridView1.Columns[i].ReadOnly = false

}

else

{

this.dataGridView1.Columns[i].ReadOnly = true

}

}

#endregion
