int periodIndex = fieldString.IndexOf(period);

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

int fldIndex = _reportClientDocument.DataDefinition.ResultFields.Find(fieldName, CrystalDecisions.ReportAppServer.DataDefModel.CrFieldDisplayNameTypeEnum.crFieldDisplayNameName, CrystalDecisions.ReportAppServer.DataDefModel.CeLocale.ceLocaleUserDefault);
if (fldIndex == -1)
// do something if not found
// do something if found... or do nothing...

If you want full qualified name, use crFieldDisplayNameLong instead of crFieldDisplayNameName, and full fieldString ...
