一段C#保存数据的示例代码 

 1 #region 保存数据
 2   public void WriteCSV(string text)
 3   {
 4     object _lock = new object();
 5     string path = Environment.CurrentDirectory + "\\生产数据";
 6     if (!Directory.Exists(path))

 8       Directory.CreateDirectory(path);
 9     }
10     string fileFullFileName = path +"\\"+ DateTime.Now.ToString("yyyy_MM_dd") + ".csv";
11     System.IO.StreamWriter sw = null;
12     if (!File.Exists(fileFullFileName))
13     {
14           FileStream fs = new FileStream(fileFullFileName, FileMode.Create);
15       using (sw = new StreamWriter(fs, Encoding.GetEncoding("GB2312")))
16       {
17         string str = "Date,Time,标签编号,条码编号,解码内容";
18         sw.WriteLine(str);
19       }
20     }

27         {
28           sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd,HH:mm:ss,") +text+'\t');//避免写入纯数字后用Excel打开显示成科学计数法的问题
29         }
30       }

36             process.Kill();    //杀进程
37         }
