EdmSchemaAttribute 类
定义
一个属性,该属性指示程序集包含映射到概念性模型中的实体类型的类。Attribute that indicates that the assembly contains classes that are mapped to entity types in a conceptual model.
public ref class EdmSchemaAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class, AllowMultiple=true)]
public sealed class EdmSchemaAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class, AllowMultiple=true)>]
type EdmSchemaAttribute = class
inherit Attribute
Public NotInheritable Class EdmSchemaAttribute

注解
此属性应用于包含实体类型的程序集。This attribute is applied to an assembly that contains entity types. 仅要求应用一次,但可以应用多次。It is only required to be applied once, but it may be applied multiple times. 当多次应用到 Visual Basic 项目中的单个程序集时, EdmSchemaAttribute 必须使用构造函数为程序集所引用的每个概念模型提供唯一的 GUID 字符串值。When it is applied multiple times to a single assembly in a Visual Basic project, the EdmSchemaAttribute constructor must be used to supply a GUID string value that is unique for each conceptual model referenced by the assembly.
构造函数
| EdmSchemaAttribute() |
初始化 EdmSchemaAttribute 类的新实例。Initializes a new instance of the EdmSchemaAttribute class. |
| EdmSchemaAttribute(String) |
使用对程序集引用的每个模型都唯一的值初始化 EdmSchemaAttribute 类的新实例。Initializes a new instance of the EdmSchemaAttribute class with a unique value for each model referenced by the assembly. |
属性
| TypeId |
在派生类中实现时,获取此 Attribute 的唯一标识符。When implemented in a derived class, gets a unique identifier for this Attribute. (继承自 Attribute) |
方法
| Equals(Object) |
返回一个值,该值指示此实例是否与指定的对象相等。Returns a value that indicates whether this instance is equal to a specified object. (继承自 Attribute) |
| GetHashCode() |
返回此实例的哈希代码。Returns the hash code for this instance. (继承自 Attribute) |
| GetType() |
获取当前实例的 Type。Gets the Type of the current instance. (继承自 Object) |
| IsDefaultAttribute() |
在派生类中重写时,指示此实例的值是否是派生类的默认值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (继承自 Attribute) |
| Match(Object) |
当在派生类中重写时,返回一个指示此实例是否等于指定对象的值。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (继承自 Attribute) |
| MemberwiseClone() |
创建当前 Object 的浅表副本。Creates a shallow copy of the current Object. (继承自 Object) |
| ToString() |
返回表示当前对象的字符串。Returns a string that represents the current object. (继承自 Object) |
显式接口实现
| _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) |
将一组名称映射为对应的一组调度标识符。Maps a set of names to a corresponding set of dispatch identifiers. (继承自 Attribute) |
| _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr) |
检索对象的类型信息,然后可以使用该信息获取接口的类型信息。Retrieves the type information for an object, which can be used to get the type information for an interface. (继承自 Attribute) |
| _Attribute.GetTypeInfoCount(UInt32) |
检索对象提供的类型信息接口的数量(0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1). (继承自 Attribute) |
| _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) |
提供对某一对象公开的属性和方法的访问。Provides access to properties and methods exposed by an object. (继承自 Attribute) |
