c# - 有没有一种方法可以搜索用户从文件中加载的文本中的特定单词并为其着色？

Question

用户指定了一个文件路径，然后将所有可读内容插入到一个字符串中，但我现在在搜索该字符串以查找用户输入的单词时遇到了问题，如果出现匹配项，我还无法为其着色。

 Console.WriteLine("Please enter the path of the document to be searched");

        do
        {

            text = Helper.TryToReadFile();
        } while (text == null);

        Console.WriteLine("Choosen Text:\n---------------------------------------\n");
        Console.WriteLine(text);
        Console.WriteLine("---------------------------------------\n");
        //
        Console.WriteLine("Would you like to search for whole words ?");
        bool decisionForWholeWords = Helper.ConvertToBool(Console.ReadLine());

        Console.WriteLine("Should the spelling be observed ?");
        bool decisionForSpelling = Helper.ConvertToBool(Console.ReadLine());

一个简单的基本逻辑

  public static void Main(string[] args)
        {
            string txt = "this is a an example string";
            string wordToFind = "example string";
            bool phraseFound = false;
            var splittedTxt = txt.Split(' ');
            var wordToFindList = wordToFind.Split(' ');
            foreach (var item in splittedTxt)
            {
                if (wordToFindList.Any(item.Contains))
                {
                    Console.BackgroundColor = ConsoleColor.Blue;
                    Console.ForegroundColor = ConsoleColor.White;
                    phraseFound = true;
                }
                Console.Write(item);
                if (phraseFound) // reset color
                {
                    Console.BackgroundColor = ConsoleColor.Black;
                    Console.ForegroundColor = ConsoleColor.Gray;
                    phraseFound = false;
                }
                Console.Write(" ");
            }


            Console.ReadLine();
        }
