C#数据库导出（入）TXT

导出：

public void ExportTxt() { var file = System.IO.File.Open(path, System.IO.FileMode.Open); using (var stream = new System.IO.StreamReader(file)) { while (!stream.EndOfStream) { string[] qwe = stream.ReadLine().Split(','); string sql = string.Format("insert into 表 values('{0}','{1}','{2}','{3}','{4}','{5}','{6}','{7}')", qwe[0], qwe[1], qwe[2], qwe[3], qwe[4], qwe[5], qwe[6], qwe[7]); } } file.Close(); }

导入：

public void WriteTxt() { System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Create); //获得字节数组 System.Data.DataTable dt = handle.ExecuteDataSet("select * from 表").Tables[0]; for (int i = 0; i < dt.Rows.Count; i++) { for (int x = 0; x < dt.Columns.Count; x++) { byte[] wr; if (x != dt.Columns.Count - 1) { wr = new UTF8Encoding(true).GetBytes(dt.Rows[i][x].ToString() + ","); } else { wr = new UTF8Encoding(true).GetBytes(dt.Rows[i][x].ToString() + "\r\n"); } //字节数组,字节偏移量,最多写入的字节数 fs.Write(wr, 0, wr.Length); } } //清空缓冲区、关闭流 fs.Flush(); fs.Close(); }
