            UIDocument uidoc = uiapp.ActiveUIDocument;

            {
                tran.Start();
 
                Family family = doc.OwnerFamily;

                SchemaBuilder bulder = new SchemaBuilder(new Guid("11111111-aaaa-2222-bbbb-333333333333"));

                bulder.SetReadAccessLevel(AccessLevel.Public);

                bulder.SetWriteAccessLevel(AccessLevel.Public);

                bulder.SetSchemaName("FamilyTest");

                bulder.SetDocumentation("Data store for socket related info in a FamilyTest");

                FieldBuilder fieldbuilder = bulder.AddSimpleField("FamilyTest", typeof(string));
                Schema schema = bulder.Finish();
                Entity ent = new Entity(schema);
                Field socketNumber = schema.GetField("FamilyTest");
                ent.Set(socketNumber, "Family______________Test");
                family.SetEntity(ent);
                MessageBox.Show("保存成功");
                tran.Commit();


            }
 
            return Result.Succeeded;
        }
    }
}

以上是存儲好了一個字段，以下是測試讀取該字段，把該文件加載到項目文件或者族文件字段都是存在的。
