C# 有时我的listBox1或我更新的值会闪烁一秒或更短时间，我如何修复它？

这是我正在更新列表框的代码：

我还有两个列表框事件：

private void listBox1_MeasureItem(object sender, MeasureItemEventArgs e)
{
    e.ItemHeight = 25;
}

private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
{
    if (e.Index == -1)
    {
    }
    else
    {

        ColorText.ColorListBox(data, e);

    }
}

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

namespace GatherLinks
{
    class ColorText
    {


        public static void Texts(RichTextBox box, string text, Color color)
        {
            box.SelectionStart = box.TextLength;
            box.SelectionLength = 0;

            box.SelectionColor = color;
            box.AppendText(text);
            box.SelectionColor = box.ForeColor;
        }

        public static void ColorListBox(List<string> data, DrawItemEventArgs e)
        {
            string strLeft = null;
            string strMid = "---";
            string strRight = null;
            if (data[e.Index].Contains(strMid))
            {
                int index = data[e.Index].IndexOf(strMid);
                strLeft = data[e.Index].Substring(0, index);
                strRight = data[e.Index].Substring(index + strMid.Length);
            }

            using (Font f = new Font(FontFamily.GenericSansSerif, 20, FontStyle.Regular))
            {
                float startPos;
                e.Graphics.DrawString(strLeft, f, Brushes.Red, e.Bounds.X, e.Bounds.Y);
                startPos = e.Graphics.MeasureString(strLeft, f).Width;
                e.Graphics.DrawString(strMid, f, Brushes.Black, e.Bounds.X + startPos, e.Bounds.Y);
                startPos = e.Graphics.MeasureString(strLeft + strMid, f).Width;
                e.Graphics.DrawString(strRight, f, Brushes.Green, e.Bounds.X + startPos, e.Bounds.Y);
            }
        }
    }
}

和另一个类中的ColorText函数，该函数为列表框中的项目着色：

private void listBox1_MeasureItem(object sender, MeasureItemEventArgs e)
{
    e.ItemHeight = 25;
}

private void listBox1_DrawItem(object sender, DrawItemEventArgs e)
{
    if (e.Index == -1)
    {
    }
    else
    {

        ColorText.ColorListBox(data, e);

    }
}

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

namespace GatherLinks
{
    class ColorText
    {


        public static void Texts(RichTextBox box, string text, Color color)
        {
            box.SelectionStart = box.TextLength;
            box.SelectionLength = 0;

            box.SelectionColor = color;
            box.AppendText(text);
            box.SelectionColor = box.ForeColor;
        }

        public static void ColorListBox(List<string> data, DrawItemEventArgs e)
        {
            string strLeft = null;
            string strMid = "---";
            string strRight = null;
            if (data[e.Index].Contains(strMid))
            {
                int index = data[e.Index].IndexOf(strMid);
                strLeft = data[e.Index].Substring(0, index);
                strRight = data[e.Index].Substring(index + strMid.Length);
            }

            using (Font f = new Font(FontFamily.GenericSansSerif, 20, FontStyle.Regular))
            {
                float startPos;
                e.Graphics.DrawString(strLeft, f, Brushes.Red, e.Bounds.X, e.Bounds.Y);
                startPos = e.Graphics.MeasureString(strLeft, f).Width;
                e.Graphics.DrawString(strMid, f, Brushes.Black, e.Bounds.X + startPos, e.Bounds.Y);
                startPos = e.Graphics.MeasureString(strLeft + strMid, f).Width;
                e.Graphics.DrawString(strRight, f, Brushes.Green, e.Bounds.X + startPos, e.Bounds.Y);
            }
        }
    }
}

如何使列表框不会每隔几秒钟或每次更新新传感器时闪烁。值？一、 我不确定具体发生的原因和时间，但ListBox项和sensor.Value正在闪烁。

我认为问题在于您正在清除数据源，然后再次设置它。不必将数据源设置为null，然后在数据更改时将其重置

尝试删除这两行，看看闪烁是否消失：

this.Invoke(new Action(() => listBox1.DataSource = null));
this.Invoke(new Action(() => listBox1.DataSource = data));

您对Invoke方法的使用是错误的，这可能是闪烁的原因

尝试如下更改代码的第一部分：

this.Invoke(new Action(() =>
    {
        data = new List<string>();
        data.Add("Gpu Temeprature --- " + sensor.Value.ToString());
        listBox1.DataSource = null;
        listBox1.DataSource = data;
        listBox1.Invalidate()
    }));

---

每次调用Invoke方法时，都会将消息发布到应用程序的消息队列，然后在UI不忙时在UI线程中处理消息。通过多次调用Invoke，您可以发送多条消息，这些消息将分别处理。

一旦我解决了这个问题，请将其添加到我的表单中：

protected override CreateParams CreateParams
{
    get
    {
        CreateParams cp = base.CreateParams;
        cp.ExStyle |= 0x02000000;  // Turn on WS_EX_COMPOSITED
        return cp;
    }
}
