OneWayAttribute 类
定义
将方法标记为单向方法,无返回值和 out 或 ref 参数。Marks a method as one way, without a return value and out or ref parameters.
public ref class OneWayAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Method)]
public class OneWayAttribute : Attribute
[System.AttributeUsage(System.AttributeTargets.Method)]
[System.Runtime.InteropServices.ComVisible(true)]
public class OneWayAttribute : Attribute
[<System.AttributeUsage(System.AttributeTargets.Method)>]
type OneWayAttribute = class
inherit Attribute
[<System.AttributeUsage(System.AttributeTargets.Method)>]
[<System.Runtime.InteropServices.ComVisible(true)>]
type OneWayAttribute = class
inherit Attribute
Public Class OneWayAttribute

注解
如果调用了单向方法,则不需要答复消息或状态或信息。When one-way methods are invoked, no reply message or status or information is expected. OneWayAttribute用于指示方法 void 仅具有返回 in 参数和参数。The OneWayAttribute is used to indicate that the method has a void return and only in parameters. 方法不能引发任何异常,并且 ref return 不支持参数和值。The method cannot throw any exceptions, and ref parameters and return values are not supported. 方法可以与调用方同步或异步执行。The method can execute synchronously or asynchronously with respect to the caller. 调用方无法假定在线程控制返回时已在服务器对象上执行了单向调用。The caller cannot make assumptions that the one-way call has executed on the server object when thread control returns.
构造函数
| OneWayAttribute() |
创建 OneWayAttribute 的实例。Creates an instance of OneWayAttribute. |
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) |
