构造函数
| DataSysDescriptionAttribute(String) |
使用指定的说明字符串初始化 DataSysDescriptionAttribute 类的新实例。Initializes a new instance of the DataSysDescriptionAttribute class using the specified description string. |
属性
| Description |
获取说明的文本。Gets the text for the description. |
| DescriptionValue |
获取或设置作为说明存储的字符串。Gets or sets the string stored as the description. (继承自 DescriptionAttribute) |
| 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) |
返回给定对象的值是否等于当前的 DescriptionAttribute。Returns whether the value of the given object is equal to the current DescriptionAttribute. (继承自 DescriptionAttribute) |
| GetHashCode() |
返回此实例的哈希代码。Returns the hash code for this instance. (继承自 DescriptionAttribute) |
| GetType() |
获取当前实例的 Type。Gets the Type of the current instance. (继承自 Object) |
| IsDefaultAttribute() |
返回一个值，该值指示这是否为默认 DescriptionAttribute 实例。Returns a value indicating whether this is the default DescriptionAttribute instance. (继承自 DescriptionAttribute) |
| 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) |
