Step2

Add a Button and change the name to Browse .

Step3

Add a DataGridView Control Inside the Form -> Add a OpenFile Dialog in bottom of the Page.

Step4

Double click on Browse Button and go to the Code View.

Step5

Please follow the below code.

private void button1_Click(object sender, EventArgs e)
{
if (openFileDialog1.ShowDialog() != DialogResult.Cancel)
{
String sLine = "";
try
{
//Pass the file you selected with the OpenFileDialog control to
//the StreamReader Constructor.
System.IO.StreamReader FileStream = new System.IO.StreamReader(openFileDialog1.FileName);
//You must set the value to false when you are programatically adding rows to
//a DataGridView. If you need to allow the user to add rows, you
//can set the value back to true after you have populated the DataGridView
dataGridView1.AllowUserToAddRows = false;
//Read the first line of the text file
sLine = FileStream.ReadLine();
//The Split Command splits a string into an array, based on the delimiter you pass.
//I chose to use a semi-colon for the text delimiter.
//Any character can be used as a delimeter in the split command.
string[] s = sLine.Split(';');
//In this example, I placed the field names in the first row.
//The for loop below is used to create the columns and use the text values in
//the first row for the column headings.
for (int i = 0; i <= s.Count() - 1; i++)
{
DataGridViewColumn colHold = new DataGridViewTextBoxColumn();
colHold.Name = "col" + System.Convert.ToString(i);
colHold.HeaderText = s[i].ToString();
dataGridView1.Columns.Add(colHold);
}
//Read the next line in the text file in order to pass it to the
//while loop below
sLine = FileStream.ReadLine();
//The while loop reads each line of text.
while (sLine != null)
{
//Adds a new row to the DataGridView for each line of text.
dataGridView1.Rows.Add();
//This for loop loops through the array in order to retrieve each
//line of text.
for (int i = 0; i <= s.Count() - 1; i++)
{
//Splits each line in the text file into a string array
s = sLine.Split(';');
//Sets the value of the cell to the value of the text retreived from the text file.
dataGridView1.Rows[dataGridView1.Rows.Count - 1].Cells[i].Value = s[i].ToString();
}
sLine = FileStream.ReadLine();
}
//Close the selected text file.
FileStream.Close();
}
catch (Exception err)
{
//Display any errors in a Message Box.
System.Windows.Forms.MessageBox.Show("Error: " + err.Message, "Program Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
}
