         InitializeComponent();
      }
      string rtkFileName = string.Empty;
      string datFileName = string.Empty;

      private void buttonOpenRTKFile_Click(object sender, EventArgs e)
      {
         if (this.openFileDialog1.ShowDialog() == DialogResult.OK)
         {
            this.textBoxRtkFileName.Text = this.openFileDialog1.FileName;
            rtkFileName = this.openFileDialog1.FileName;
         }

      private void buttonConvertScs_Click(object sender, EventArgs e)
      {

         {
            return;
         }
         this.textBoxDatFileName.Text = this.saveFileDialog1.FileName;
         this.datFileName = this.saveFileDialog1.FileName;
         StreamReader streamReader = new StreamReader(rtkFileName, System.Text.Encoding.Default);
         StreamWriter streamWriter = new StreamWriter(datFileName, false, System.Text.Encoding.Default);
         //streamWriter.AutoFlush = true;

         char[] split = new char[] { '\t', ' ', ',' };
         string[] colStr;
         int count = 0;          //计算读取文件中总的行数
         while (!streamReader.EndOfStream)
         {
            colStr = streamReader.ReadLine().Split(split);
            if (colStr.Length == 5)
            {
                  count++;
            }
         }

         streamReader.BaseStream.Position = 0;
         streamWriter.WriteLine(count);

         while (!streamReader.EndOfStream)
         {
            colStr = streamReader.ReadLine().Split(split);
            if (colStr.Length == 5)
            {
                  //streamWriter.WriteLine(colStr[0]+","+colStr[3]+","+colStr[2]+","+colStr[4]);
                  streamWriter.WriteLine(colStr[0]);
                  streamWriter.WriteLine(colStr[3]);
                  streamWriter.WriteLine(colStr[2]);
                  streamWriter.WriteLine(colStr[4]);
                  streamWriter.WriteLine();
            }
         }

         streamReader.Close();
         streamWriter.Close();
      }
}
}

源文件A格式为:
L0 0000000 557.146 680.298 966.984
L1 0000000 9464.079 839.310 969.298
L2 0000000 462.461 840.370 969.247
L3 0000000 467.497 858.105 969.987
L4 0000000 469.736 858.497 970.008
L5 0000000 475.176 873.267 970.722

A转换后的格式为B:
6
L0
680.298
557.146
966.984

L1
839.310
464.079
969.298

L2
840.370
462.461
969.247

L3
858.105
467.497
969.987

L4
858.497
469.736
970.008

L5
873.267
475.176
970.722

现在如何再把B格式的文件再转换成A格式文件?请高手给与帮助,谢谢
