Getting the data from datatable in asp.net

in my web application i am using datatable and inserting outlook contacts in that. this is my code

    DataTable myTable = new DataTable();
    DataRow dr = myTable.NewRow();
    DataColumn myDataColumn = new DataColumn();
    myDataColumn.DataType = Type.GetType("System.String");
    myDataColumn.ColumnName = "Email";
    myTable.Columns.Add(myDataColumn);        

    Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
    foreach (Microsoft.Office.Interop.Outlook.AddressList addList in oApp.Session.AddressLists)
    {

        foreach (Microsoft.Office.Interop.Outlook.AddressEntry addEntry in addList.AddressEntries)
        {
        开发者_运维问答    dr["Email"] = addEntry.Address.ToString();
            myTable.Rows.Add(dr);
            dr = myTable.NewRow();
            //Response.Write(addEntry.Address.ToString());
        }

    }

My doubt is can i write the code like this when contact is insert into mytable. the details of the row can read into a string like this

string s= myTable.Rows[0]["Email"].ToString(); in foreach

You can use the DataRow collection of the foreach loop and get the corresponding row values.

foreach (DataRow dr in myTable.Rows)
{
    // Specify the column name or column index of the datacolumn
    //dr["ColumnName"].ToString();
}

or you can use a DataView of the DataTable and iterate through the DataRowView collection

DataView dv = myTable.DefaultView;

foreach (DataRowView drv in dv)
{
    drv.Row["ColumnName"].ToString();
}
