WinForm利用 RichTextBox组件实现输出各种颜色字体日志信息

news 2025/8/9 7:11:07

引言

   利用颜色来更好辨别输出日志信息，好了其他的不多说了，直接奔入主图吧。

效果图

实现代码

/// <summary>
/// 输出并设置字体颜色
/// </summary>
/// <param name="msg"></param>
/// <param name="color"></param>
private void WiterLog(string msg, Color color)
{this.Invoke(new Action(() =>{txtBoxResultInfo.SuspendLayout();txtBoxResultInfo.SelectionStart = txtBoxResultInfo.TextLength;txtBoxResultInfo.SelectionLength = 0;txtBoxResultInfo.SelectionColor = color;txtBoxResultInfo.AppendText(msg + Environment.NewLine);txtBoxResultInfo.SelectionColor = txtBoxResultInfo.ForeColor;// 滚动到TextBox的最后一行txtBoxResultInfo.ScrollToCaret();txtBoxResultInfo.ResumeLayout();}));
}

完整的示例代码

namespace WinFormsApp1
{public partial class Form1 : Form{public Form1(){InitializeComponent();}private void button1_Click(object sender, EventArgs e){Random rand = new Random();for (int i = 1; i <= 50; i++){// 生成随机颜色Color randomColor = Color.FromArgb(rand.Next(100, 256),rand.Next(100, 256),rand.Next(100, 256));// 生成随机文字string text = GenerateRandomString();WiterLog($"{i}、{text}", randomColor);}}private string GenerateRandomString(){Random rand = new Random();int length = rand.Next(20, 50);// 常见汉字字符集string chineseChars = "的一是了我不人在有他这为之大来以个中上们到说国和地也子时道出而于就得里后自之者发经行家方如事成";// 生成随机中文字符char[] chars = new char[length];for (int i = 0; i < length; i++){chars[i] = chineseChars[rand.Next(chineseChars.Length)];}return new string(chars);}/// <summary>/// 输出并设置字体颜色/// </summary>/// <param name="msg"></param>/// <param name="color"></param>private void WiterLog(string msg, Color color){this.Invoke(new Action(() =>{txtBoxResultInfo.SuspendLayout();txtBoxResultInfo.SelectionStart = txtBoxResultInfo.TextLength;txtBoxResultInfo.SelectionLength = 0;txtBoxResultInfo.SelectionColor = color;txtBoxResultInfo.AppendText(msg + Environment.NewLine);txtBoxResultInfo.SelectionColor = txtBoxResultInfo.ForeColor;// 滚动到TextBox的最后一行txtBoxResultInfo.ScrollToCaret();txtBoxResultInfo.ResumeLayout();}));}}
}
