C#使用ListView更新数据出现闪烁解决办法

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

 public class DoubleBufferListView : ListView

     {

         public DoubleBufferListView()

         {

             SetStyle(ControlStyles.DoubleBuffer |

               ControlStyles.OptimizedDoubleBuffer |

               ControlStyles.AllPaintingInWmPaint, true);

             UpdateStyles();

         }

     }

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)()));

            this.doubleBufferListView1.FullRowSelect = true;

            this.doubleBufferListView1.HideSelection = false;

            this.doubleBufferListView1.Location = new System.Drawing.Point(, );

            this.doubleBufferListView1.Name = "doubleBufferListView1";

            this.doubleBufferListView1.Size = new System.Drawing.Size(, );

            this.doubleBufferListView1.TabIndex = ;

            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", , System.Windows.Forms.HorizontalAlignment.Left);

            doubleBufferListView1.Columns.Add("value", , System.Windows.Forms.HorizontalAlignment.Right);

            doubleBufferListView1.Columns.Add("Action", , System.Windows.Forms.HorizontalAlignment.Left);

            doubleBufferListView1.Columns.Add("value", , System.Windows.Forms.HorizontalAlignment.Left);

4.随便添加点内容

         string[] listViewData = new string[];

            listViewData[] = "Action";

            listViewData[] = "";

            listViewData[] = "Action";

            listViewData[] = "";

            ListViewItem lvItem = new ListViewItem(listViewData, );

            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(, ).ToString();

                label1.Text = temp;

                this.doubleBufferListView1.Items[].SubItems[].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
