C # Read text and display data in the Dev Control

The following is an example of the text data to be read.

Inventory management-inventory transaction history
Transaction ID Transaction date commodity code

218478808 2100325K0150
218478810 2100325K0145
218478812 2100325K0131
218478814 2100328K0066
The text is separated.

The FrmReaderFile. cs code is as follows:

Using System; using System. collections. generic; using System. componentModel; using System. data; using System. drawing; using System. linq; using System. text; using System. windows. forms; using System. IO; using System. collections; namespace sms {public partial class FrmReaderFile: Form {public FrmReaderFile () {InitializeComponent ();} private void button#click (object sender, EventArgs e) {DataTable dt = new DataTable (); // which of the following columns are generated cyclically? Dt. columns. add ("thing ID"); dt. columns. add ("date"); dt. columns. add ("Product Code"); dt. columns. add ("4"); dt. columns. add ("5"); dt. columns. add ("6 ");

String strFilePath = @ "E:/data report .txt"; if (! File. Exists (strFilePath) {MessageBox. Show ("text File not found! "," Prompt ", MessageBoxButtons. OK,

MessageBoxIcon .Error);                return;            }            else            {  FileStream fs = new FileStream(strFilePath, FileMode.Open, FileAccess.Read);  StreamReader sr = new StreamReader(fs, Encoding.GetEncoding("gb2312"));string strLine = sr.ReadLine();                int count =0;                while (strLine != null)                {                    string[] strArry = strLine.Split();                    DataRow dr = dt.NewRow();                    for (int i = 0; i <= strArry.Length - 1; i++)                    {                        dr[i] = strArry[i];                    }                    dt.Rows.Add(dr);                    strLine = sr.ReadLine();                }                sr.Close();                fs.Close();                gridControl1.DataSource = dt;            }               }}

Example running effect:

Question 1: How can I read and display the data after the third row?

Question 2: How to read the data in the second row and use it as the column name?
