注解
ComplexObject 实现复杂类型的基本功能。 有关详细信息，请参阅 复杂类型对象。
使用概念模型实现自定义数据类时，建议表示复杂类型的数据类继承自 ComplexObject。 有关详细信息，请参阅 自定义对象。
复杂类型可以是实体类型的属性或其他复杂类型的属性。
复杂类型由实体类型的非标量属性返回。 这样允许在实体内组织标量属性。 与实体相似，复杂类型由标量属性或者其他复杂类型属性组成。 不能在没有关联的实体类型的情况下使用复杂类型。 由于复杂类型没有键，因此如果没有关联的实体类型，则无法管理复杂类型对象。 有关详细信息，请参阅 复杂类型对象。
构造函数
| ComplexObject() |
创建 ComplexObject 的实例。 |
方法
| Equals(Object) |
确定指定对象是否等于当前对象。 (继承自 Object) |
| GetHashCode() |
作为默认哈希函数。 (继承自 Object) |
| GetType() |
获取当前实例的 Type。 (继承自 Object) |
| GetValidValue<T>(T, String, Boolean, Boolean) |
返回指定属性的复杂类型。 (继承自 StructuralObject) |
| MemberwiseClone() |
创建当前 Object 的浅表副本。 (继承自 Object) |
| OnPropertyChanged(String) |
引发 PropertyChanged 事件。 (继承自 StructuralObject) |
| OnPropertyChanging(String) |
引发 PropertyChanging 事件。 (继承自 StructuralObject) |
| ReportPropertyChanged(String) |
通知更改跟踪器，某个复杂对象的属性已更改。 |
| ReportPropertyChanging(String) |
通知更改跟踪器，对复杂对象的属性更改挂起。 |
| SetValidValue<T>(T, T, String) |
设置指定属性的复杂对象。 (继承自 StructuralObject) |
| ToString() |
返回表示当前对象的字符串。 (继承自 Object) |
事件
| PropertyChanged |
在属性值更改时发生。 (继承自 StructuralObject) |
| PropertyChanging |
在属性值更改挂起时发生。 (继承自 StructuralObject) |
