Answer 1

Use linq and set the data table as Enumerable and select the fields from the data table field that matches what you are looking for.

Example

I want to get the currency Id and currency Name from the currency table where currency is local currency, and assign the currency id and name to a text boxes on the form:

DataTable dt = curData.loadCurrency();
            var curId = from c in dt.AsEnumerable()
                        where c.Field("LocalCurrency") == true
                        select c.Field("CURID");

            foreach (int cid in curId)
            {
                txtCURID.Text = cid.ToString();
            }
            var curName = from c in dt.AsEnumerable()
                          where c.Field("LocalCurrency") == true
                          select c.Field("CurName");
            foreach (string cName in curName)
            {
                txtCurrency.Text = cName.ToString();
            }
