Read the access dataset   

For excel 2007:

    private DataSet GetExcelData(string str)
    {
        string strCon = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" + str + "; Extended Properties=\"Excel 12.0; HDR=YES\"";
        OleDbConnection myConn = new OleDbConnection(strCon);
        string strCom = " SELECT * FROM [Sheet1$]";
        myConn.Open();
        OleDbDataAdapter myCommand = new OleDbDataAdapter(strCom, myConn);
        DataSet myDataSet = new DataSet();
        myCommand.Fill(myDataSet, "[Sheet1$]");
        myConn.Close();
        return myDataSet;
    }

For excel2003:

The connection string is changed to:

string strCon = " Provider = Microsoft.Jet.OLEDB.4.0 ; Data Source ="+str+"; Extended Properties=Excel 8.0";

Optimized the code

  1. public static DataSet GetExcelData(string str, string version)
  2.         {
  3.             string strCon = "";
  4.             if (version.Equals("2003")) {
  5.                 strCon = " Provider = Microsoft.Jet.OLEDB.4.0 ; Data Source =" + str + ";Extended Properties=Excel 8.0";
  6.             }
  7.             if (version.Equals("2007")) {
  8.                 strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + str + ";Extended Properties="Excel 12.0;HDR=YES"";
  9.             }
  10.             OleDbConnection myConn = new OleDbConnection(strCon);
  11.             string strCom = " SELECT * FROM [Sheet1$]";
  12.             myConn.Open();
  13.             OleDbDataAdapter myCommand = new OleDbDataAdapter(strCom, myConn);
  14.             DataSet myDataSet = new DataSet();
  15.             myCommand.Fill(myDataSet, "[Sheet1$]");
  16.             myConn.Close();
  17.             return myDataSet;
  18.             
  19.         }
