GetCustomAttributes(Type, Boolean)

Source:: Module.cs

Source:: Module.cs

Source:: Module.cs

获取指定类型的自定义属性。

public:
 virtual cli::array <System::Object ^> ^ GetCustomAttributes(Type ^ attributeType, bool inherit);

public virtual object[] GetCustomAttributes (Type attributeType, bool inherit);

abstract member GetCustomAttributes : Type * bool -> obj[]
override this.GetCustomAttributes : Type * bool -> obj[]

Public Overridable Function GetCustomAttributes (attributeType As Type, inherit As Boolean) As Object()

参数

attributeType: Type

要获取的特性的类型。

inherit: Boolean

对于该类型的对象，将忽略此自变量。

Object[]

Object 类型的数组，包含指定类型的所有自定义属性。

实现

GetCustomAttributes(Type, Boolean)

例外

ArgumentNullException

attributeType 为 null。

ArgumentException

attributeType 不是由运行时提供的 Type 对象。例如，attributeType 是一个 TypeBuilder 对象。
