在每一行的开头和结尾添加空格 C#

Question

我正在为和弦创建一个程序。我需要在每一行的开头和每一行的结尾都有一个 space，所以程序可以识别 chords.Here 是替换的，但我不知道如何添加空白 spaces.

 richTextBox1.Text = richTextBox1.Text.Replace(" H ", " X ").Replace(" A# ", " H ").Replace(" A ", " A# ").Replace(" G# ", " A ").Replace(" G ", " G# ").Replace(" F# ", " G ").Replace(" F ", " F# ")
               .Replace(" E ", " F ").Replace(" D# ", " E ").Replace(" D ", " D# ").Replace(" C# ", " D ").Replace(" C ", " C# ").Replace(" X ", " C ")


               .Replace(" Hm ", " Xm ").Replace(" A#m ", " Hm ").Replace(" Am ", " A#m ").Replace(" G#m ", " Am ").Replace(" Gm ", " G#m ").Replace(" F#m ", " Gm ").Replace(" Fm ", " F#m ")
               .Replace(" Em ", " Fm ").Replace(" D#m ", " Em ").Replace(" Dm ", " D#m ").Replace(" C#m ", " Dm ").Replace(" Cm ", " C#m ").Replace(" Xm ", " Cm ");

我创建了一些文本文件（每一行的开头和结尾都没有 space），例如： HX ＃H 一个# G#A G## F#G F# 这是制作新文件的代码，每行前面和末尾都带有 space 我希望这会如您所愿：



using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
namespace StringLineSpaceAdd
{
    class Program
    {
        static void Main(string[] args)
        {
            TextReader r = File.OpenText(@"D:\myFile.txt");
            string currentLine="";
            HashSet<string> previousLines = new HashSet<string>();
            TextWriter w = File.CreateText(@"D:\newFile.txt");
            while ((currentLine = r.ReadLine()) != null)
            {
                // Add returns true if it was actually added,
                // false if it was already there
                if (previousLines.Add(currentLine))
                {
                    currentLine = " " + currentLine + " ";
                    w.WriteLine(currentLine);
                }
            }
            w.Close();
        }
    }
}
