//using C# code..Import Excel File in using open file dialog and save Excel sheet name in combo box...

OpenFileDialog openDialog = new OpenFileDialog();
               openDialog.Title = "Select file";
               openDialog.InitialDirectory = @"c:\";
               openDialog.Filter = "Excel Sheet(*.xlsx)|*.xlsx|All Files(*.*)|*.*";
               openDialog.FilterIndex = 1;
               openDialog.RestoreDirectory = true;
               if (openDialog.ShowDialog() == DialogResult.OK)
               {
                   if (openDialog.FileName != "")
                   {
                       strExcelPathName = openDialog.FileName;
                       cmbExcelSheet.DataSource = GetSheetNames(openDialog.FileName);
                   }
                   else
                   {
                       MessageBox.Show("chose Excel sheet path..", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
                   }
               }

           }
           catch (Exception ex)
           {
               MessageBox.Show(ex.Message.ToString());
           }

then..write this code in button Click Event to show in DataGridview....

C#

if (System.IO.File.Exists(strExcelPathName))
               {
                   string connectionString = String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 8.0;HDR=YES;IMEX=1;""",strExcelPathName);

                   //string connectionString = String.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 8.0;HDR=YES;IMEX=1;""", txtPath.Text);
                   string query = String.Format("select * from [{0}$]",cmbExcelSheet.SelectedItem);
                   OleDbDataAdapter dataAdapter = new OleDbDataAdapter(query, connectionString);
                   DataSet dataSet = new DataSet();
                   dataAdapter.Fill(dataSet);
                   DataTable dtView = dataSet.Tables[0];
                   if (dtView.Rows.Count > 0)
                   {
                       dgrdReciver.Rows.Clear();
                       dgrdReciver.Rows.Add(dtView.Rows.Count);
                       int i = 0;
                       foreach (DataRow drow in dtView.Rows)
                       {
                           //dgrdReciver.Rows[i].Cells["SerialNo"].Value = j;
                           dgrdReciver.Rows[i].Cells["Addressid"].Value = drow["ADRSID"];
                           dgrdReciver.Rows[i].Cells["ReciverName"].Value = drow["NAME"];
                           dgrdReciver.Rows[i].Cells["companyName"].Value = drow["COMPANY"];
                           dgrdReciver.Rows[i].Cells["RecvAddress"].Value = drow["ADDRESS"];
                           dgrdReciver.Rows[i].Cells["ReciverState"].Value = drow["STATE"];
                           dgrdReciver.Rows[i].Cells["ReciverCity"].Value = drow["CITY"];
                           dgrdReciver.Rows[i].Cells["RecvCountryCode"].Value = drow["CONTRY CODE"];
                           dgrdReciver.Rows[i].Cells["ReciverPostal"].Value = drow["POSTAL CODE"];
                           dgrdReciver.Rows[i].Cells["RecvContactNo"].Value = drow["CONTACT NO"];
                           i++;
                       }

                   }
               }
               else
               {
                   MessageBox.Show("No File is Selected");
               }
