PrePrepareMethodAttribute 类
定义
注意
The Constrained Execution Region (CER) feature is not supported.
指示本机图像生成服务准备一个要包含在受约束的执行区域 (CER) 中的方法。Instructs the native image generation service to prepare a method for inclusion in a constrained execution region (CER).

注解
将特性应用于 PrePrepareMethodAttribute 方法或构造函数,以指示本机映像生成服务该方法 (及其可静态确定的调用关系图) 准备好在 CER 中使用。Apply the PrePrepareMethodAttribute attribute to a method or constructor to tell the native image generation service that the method (and its statically determinable call graph) is to be prepared for use in a CER. 如果应用该属性的方法将在运行时显式准备,并且该方法的作者知道这一点,并且想要避免运行时准备的开销,则此属性很有用。This attribute is useful if the method to which it is applied will be prepared explicitly at run time, and the author of the method knows this and wants to avoid the overhead of run-time preparation.
构造函数
| PrePrepareMethodAttribute() |
初始化 PrePrepareMethodAttribute 类的新实例。Initializes a new instance of the PrePrepareMethodAttribute class. |
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) |
