Create Field object in RAS

To add field onto report, create a field object first ..

private Field ConvertFieldStringToFieldClass(string fieldString)

{

// get the period index

    char period = '.';

    int periodIndex = fieldString.IndexOf(period);

// parse out table and field name

    string tableName = fieldString.Substring(1, periodIndex-1);

    string fieldName = fieldString.Substring(periodIndex+1, fieldString.Length-(periodIndex+2));

    Tables tables = _reportClientDocument.DatabaseController.Database.Tables;

    int tableIndex = tables.FindByAlias(tableName);

    CrystalDecisions.ReportAppServer.DataDefModel.Table table =

(CrystalDecisions.ReportAppServer.DataDefModel.Table)tables[tableIndex];



    Fields fields = table.DataFields;

    int fieldIndex = fields.Find(fieldName,    CrFieldDisplayNameTypeEnum.crFieldDisplayNameName,

CrystalDecisions.ReportAppServer.DataDefModel.CeLocale.ceLocaleEnglishUS);

    Field field = (Field)fields[fieldIndex];

    return field;
