c#逐行分元素读取记事本txt数据写进数据库

其实这里最关键的一个方法是 StreamReader类里的 ReadLine();这个方法可以逐行读取txt流里面的数据。写了个简单的demo，已经加上了详细的注释说明。

 

ok，好了，不废话，下面直接上代码

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34

public void InputData()          {              DataTable dt = new DataTable();              string strFilePath = "e:\\ouput1.txt";              FileStream fs = new FileStream(strFilePath, FileMode.Open, FileAccess.Read);              StreamReader sr = new StreamReader(fs, System.Text.Encoding.UTF8);//utf-8格式，下面的是gb2312格式              ///StreamReader sr = new StreamReader(fs, System.Text.Encoding.Default);                  //SqlConnection conn = DatabaseConnection.GetConnected();              //conn.Open();              string strLine0 = sr.ReadLine();              ///当行内需要重新分散元素的是时候，我注释掉以下代码，demo里，用“，”区分行元素，然后，用ado.net插入数据库就可以了              /*             String strLine1 = sr.ReadLine();             String strLine2 = sr.ReadLine();*/              while (strLine0 != null)              {                  string[] strArray = new string[4];                  strArray = strLine0.Split('，');                  DataRow dr = dt.NewRow();                  dr[0] = strArray[0];                  dr[1] = strArray[1];                  dr[2] = strArray[2];                  dr[3] = strArray[3];                  //string sql = "insert into 你的表名 values('" + dr[0] + "','" + dr[1] + "','" + dr[2] + "','" + dr[3] + "')";                  //SqlCommand cmd = new SqlCommand(sql, conn);                  //cmd.ExecuteNonQuery();                  dt.Rows.Add(dr);                  strLine0 = sr.ReadLine();              }              sr.Close();              fs.Close();              //conn.Close();          }
