文字檔案的讀寫操作是程式設計過程中的基礎，這裡提供一種常用的文字檔案讀寫操作方法。

        /// <summary>
        /// 寫入txt
        /// </summary>
        /// <param name="pPath">寫入文字路徑</param>
        /// <param name="pStringList">資料集</param>
        public void WriteToTXT(string pPath, List<string> pStringList)
        {
            FileStream pFileStream = new
 
 FileStream(pPath, FileMode.Create);
            StreamWriter pStreamWriter = new StreamWriter(pFileStream);
            if (pStringList != null)
            {
                foreach (var item in pStringList)
                {
                    pStreamWriter.WriteLine(item);
                }
            }
            pStreamWriter.Flush();//清空緩衝區
 

            pStreamWriter.Close();//關閉流
            pFileStream.Close();//關閉流
        }

        /// <summary>
        /// 讀取txt
        /// </summary>
        /// <param name="pPath">txt檔案路徑</param>
        /// <returns>返回讀取的資料集</returns>
        public List<string> ReadTxt(string
 
 pPath)
        {
            List<string> pList = new List<string>();
            using (StreamReader reader = new StreamReader(pPath, Encoding.Default))
            {
                //迴圈讀取所有行
                while (!reader.EndOfStream)
                {
                    string line = Regex.Replace(reader.ReadLine(), "\\s{2,}", " ");
                    if (line == "")
                    {
                        continue;
                    }
                    pList.Add(line);
                }
            }
            return pList;
        }
