C# ListView双缓存代码，解决闪屏问题

首先，自定义一个类ListViewNF，继承自 System.Windows.Forms.ListView。

代码：

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;

namespace ListViewDoubleTest

{
    class ListViewNF : System.Windows.Forms.ListView
    {
        public ListViewNF()
        {
            // 开启双缓冲
            this.SetStyle(ControlStyles.OptimizedDoubleBuffer | ControlStyles.AllPaintingInWmPaint, true);

            // Enable the OnNotifyMessage event so we get a chance to filter out 
            // Windows messages before they get to the form's WndProc
            this.SetStyle(ControlStyles.EnableNotifyMessage, true);
        }

        protected override void OnNotifyMessage(Message m)
        {
            //Filter out the WM_ERASEBKGND message
            if (m.Msg != 0x14)
            {
                base.OnNotifyMessage(m);
            }
        }
    }
}

然后，找到我们的Form代码中定义ListView的位置(Form1.Designer.cs)

将原来的 System.Windows.Forms.ListView listView1 修改。

示例：

this.listView1 = new ListViewDoubleTest.ListViewNF();

private ListViewNF listView1;
