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;
