Answer 1

Are you pulling the excel sheet into a DataTable like so?

OleDbDataAdapter cmd = new System.Data.OleDb.OleDbDataAdapter(   
            "select * from [" + worksheetName + "$]", con);   

        con.Open();   
        System.Data.DataSet excelDataSet = new DataSet();   
        cmd.Fill(excelDataSet);   
        con.Close();  

If so just iterate through the DataRows like normal.

foreach(DataRow dataRow in excelDataSet.Tables[0].Rows){
    if(dataRow["columnName"].ToString().Equals("vipin")){
       count++;
    }
}
