FastColoredTextBox XML 前景色

Question

刚刚在我的 Winform 中添加了一个 fastcoloredtextbox 并将语言设置为 XML。无法更改样式。我怎样才能改变蓝色和红色。

using FastColoredTextBoxNS;
using System.Drawing;
using System.Windows.Forms;

namespace JFlowV2
{
    public partial class BaseFastColoredTextBox : FastColoredTextBox
    {
        public BaseFastColoredTextBox()
        {
            this.Load += BaseFastColoredTextBox_Load;
        }

        private void BaseFastColoredTextBox_Load(object sender, System.EventArgs e)
        {
            ApplyDarkTheme();
        }

        public void ApplyDarkTheme()
        {
            this.BackColor = Color.FromArgb(30, 30, 30); // Editor background
            this.ForeColor = Color.FromArgb(220, 220, 220); // Editor text
            this.IndentBackColor = Color.FromArgb(45, 45, 48); // Indentation background
            this.ServiceLinesColor = Color.FromArgb(50, 50, 50); // Service lines
            this.LineNumberColor = Color.FromArgb(43, 145, 175); // Line numbers
            this.SelectionColor = Color.FromArgb(60, 75, 110, 175); // Selection color
            this.CurrentLineColor = Color.FromArgb(40, 40, 40); // Current line highlight

        }
    }
}

您需要修改应用于每个 XML 元素（例如标签、属性和值）的样式。您还需要通过定义自己的文本样式来覆盖用于 XML 令牌的样式

因此，在您的情况下，添加到 ApplyDarkTheme() 中的现有代码中，如下所示

 tagStyle = new TextStyle(new SolidBrush(Color.LightBlue), null, FontStyle.Regular);         // Color for tags
        attributeNameStyle = new TextStyle(new SolidBrush(Color.LightCoral), null, FontStyle.Regular); // Color for attribute names
        attributeValueStyle = new TextStyle(new SolidBrush(Color.LightGreen), null, FontStyle.Regular); // Color for attribute values

        // Apply the custom styles
        this.Language = Language.Custom;
        this.ClearStylesBuffer();
        this.AddStyle(tagStyle);
        this.AddStyle(attributeNameStyle);
        this.AddStyle(attributeValueStyle);

        // Set up the rules for XML elements
        this.Range.ClearStyle(StyleIndex.All);
        this.Range.SetStyle(tagStyle, @"</?[a-zA-Z]+");                       // Tag name (e.g., <tag> or </tag>)
        this.Range.SetStyle(attributeNameStyle, @"\b[a-zA-Z0-9_:-]+(?=\=)");   // Attribute names (e.g., name=)
        this.Range.SetStyle(attributeValueStyle, @"""[^""]*""");               // Attribute values (e.g., "value")
