创建txt文件并写如数据

1. 创建文件

public static void WriteDataFile(string message, string fileName)
        {
            FileStream fs = null;
            StreamWriter sw = null;
            string headStr = "测量点\t数据时间\t正向有功总\t正向有功尖\t正向有功峰\t正向有功平\t正向有功谷\t正向无功总\t正向无功尖\t正向无功峰\t正向无功平\t正向无功谷\t反向有功总\t反向无功总\t有功功率总\t有功功率A相\t有功功率B相\t有功功率C相\t无功功率总\t无功功率A相\t无功功率B相\t无功功率C相\t功率因数总\t功率因数A相\t功率因数B相\t功率因数C相\t电压A\t电压B\t电压C\t电流A\t电流B\t电流C";
            bool isNew = false;

            string fileNameD = DateTime.Today.ToString("yyyyMMdd");
            string bsFileName = Application.StartupPath + ("/Data/" + fileNameD + "/" + fileName + "Data.txt");
            if (File.Exists(bsFileName) == false)
            {
                fs = new FileStream(bsFileName, FileMode.Create);
                fs.Close();
                isNew = true;
            }
            
            try
            {
                lock (bsFileName)
                { 
                    fs = new FileStream(bsFileName, FileMode.Append, FileAccess.Write);
                    sw = new StreamWriter(fs);
                    if (message == "")
                    {
                        if (isNew == true)
                        {
                            sw.WriteLine(headStr);
                        }
                    }
                    else
                    {
                        sw.WriteLine(message);
                    }
                }
            }
            catch (Exception ee)
            {
                Console.Write(ee.ToString());
                Log log = Log.Instance();
                log.Error("WriteFile" + ee.ToString());
            }
            finally
            {
                if (fs != null)
                {
                    sw.Close();
                }
                if (fs != null)
                {
                    fs.Close();
                }
            }
            
        }

2.  写入数据或穿件文件

Common.WriteDemandFile(Protocol.AnalyseDataKeDong(message), dataFileName);
