{ Table parcels = Table.OpenFileGeodatabaseTable(@"C:\Data\Montgomery.gdb", "parcels"); //check that the "ZONING_S" column of the "parcels" feature class has a Domain assigned if (parcels.Columns["ZONING_S"].HasDomain) { //return the Domain Domain domain = parcels.Columns["ZONING_S"].GetDomain(); //check the Domain type if (domain.Type == DomainType.CodedValue) { CodedValueDomain cvDom = domain as CodedValueDomain; //Print the properties for this coded value domain System.Diagnostics.Debug.Print(cvDom.Name); //Prints "ZoningCodes" System.Diagnostics.Debug.Print(cvDom.Type.ToString()); //Prints "CodedValue" System.Diagnostics.Debug.Print(cvDom.Description); //Prints "Simplified zoning codes" System.Diagnostics.Debug.Print(cvDom.ColumnType.ToString()); //Prints "String" System.Diagnostics.Debug.Print(cvDom.Count.ToString()); //Prints "7" } } }
