使用反射给泛型类赋值
public static List<T> ToList<T>( this OracleDataReader reader ) { List<T> list = new List<T>(); Type type = typeof( T ); while( reader.Read() ) { T t = Activator.CreateInstance<T>(); int filedCount = reader.FieldCount; for( int i = 0 ; i < filedCount ; i ++ ) { var property = type.GetProperty( reader.GetName( i ) ); object value = reader[ i ]; if( property != null && property.CanWrite && !( value is DBNull ) ) { property.SetValue( t , value , null ); } } list.Add( t ); } return list; }
