在使用vs自动控件ListView控件时候，更新里面的部分代码时候出现闪烁的情况

如图：

解决以后：

解决办法使用双缓冲：添加新类继承ListView 对其重写

 1 public class DoubleBufferListView : ListView 2     { 3         public DoubleBufferListView() 4         { 5             SetStyle(ControlStyles.DoubleBuffer | 6               ControlStyles.OptimizedDoubleBuffer | 7               ControlStyles.AllPaintingInWmPaint, true); 8             UpdateStyles(); 9         }10     }

新建一个DemoTest测试

1.添加一个DoubleBufferListView的实例

 　　　　　　DoubleBufferListView doubleBufferListView1= new DoubleBufferListView();            //             // doubleBufferListView1            //             this.doubleBufferListView1.Font = new System.Drawing.Font("微软雅黑", 10.5F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(134)));            this.doubleBufferListView1.FullRowSelect = true;            this.doubleBufferListView1.HideSelection = false;            this.doubleBufferListView1.Location = new System.Drawing.Point(50, 37);            this.doubleBufferListView1.Name = "doubleBufferListView1";            this.doubleBufferListView1.Size = new System.Drawing.Size(400, 191);            this.doubleBufferListView1.TabIndex = 2;            this.doubleBufferListView1.UseCompatibleStateImageBehavior = false;            this.doubleBufferListView1.View = System.Windows.Forms.View.Details;

2.将其添加到form窗体里面

 this.Controls.Add(this.doubleBufferListView1);

3.给添加列

        doubleBufferListView1.Clear();            doubleBufferListView1.Columns.Add("Action", 80, System.Windows.Forms.HorizontalAlignment.Left);            doubleBufferListView1.Columns.Add("value", 80, System.Windows.Forms.HorizontalAlignment.Right);            doubleBufferListView1.Columns.Add("Action", 80, System.Windows.Forms.HorizontalAlignment.Left);            doubleBufferListView1.Columns.Add("value", 80, System.Windows.Forms.HorizontalAlignment.Left);

4.随便添加点内容

         string[] listViewData = new string[4];            listViewData[0] = "Action";            listViewData[1] = "1";            listViewData[2] = "Action";            listViewData[3] = "1";            ListViewItem lvItem = new ListViewItem(listViewData, 0);            doubleBufferView1.Items.Add(lvItem);

5.点击按钮开始运行

 private void button1_Click(object sender, EventArgs e)        {            Thread th = new Thread(PlayGame);            if (state == false)            {                state = true;                button1.Text = "停止";                th.IsBackground = true;                th.Name = "新线程";                th.Start();            }            else            {                state = false;                button1.Text = "开始";            }        }        private void PlayGame()        {            Random r = new Random();            while (state)            {                string temp = r.Next(0, 10).ToString();                label1.Text = temp;                this.doubleBufferListView1.Items[0].SubItems[1].Text = temp;            }        }

6.运行对比图：

左侧是解决闪屏后，右侧是自带的ListView效果
