First need to add the reference “Microsoft.Office.Interop.Excel”. You can add it from .Net components.

Add an open Dialog box control, Datagridview1, Textbox control and two Command buttons on form

using Excel = Microsoft.Office.Interop.Excel;

private voidbutton1_Click(object sender, EventArgs e)

{

if (openFileDialog1.ShowDialog()==DialogResult.OK)

textBox1.Text=openFileDialog1.FileName;

}

private voidbutton2_Click(object sender, EventArgs e)

{

try

{

System.Data.OleDb.OleDbConnectionMyCnn ;

System.Data.DataSet DSet ;

System.Data.OleDb.OleDbDataAdapterMyCmd ;

MyCnn = new System.Data.OleDb.OleDbConnection(“provider=Microsoft.Jet.OLEDB.4.0;Data Source=” + textBox1.Text + ” ;Extended Properties=Excel 8.0;”);

MyCmd = new System.Data.OleDb.OleDbDataAdapter

(“select * from [Sheet1$]”, MyCnn);

MyCmd.TableMappings.Add(“Table”, “TestTable”);

DSet = new System.Data.DataSet();

MyCmd.Fill(DSet);

dataGridView1.DataSource = DSet.Tables[0];

MyCnn.Close();

}

catch (Exceptionex)

{

MessageBox.Show (ex.ToString());

}
