ConstructorBuilder.IsDefined(Type, Boolean) 方法
定义
检查是否定义了指定的自定义属性类型。Checks if the specified custom attribute type is defined.
public:
override bool IsDefined(Type ^ attributeType, bool inherit);
public override bool IsDefined (Type attributeType, bool inherit);
override this.IsDefined : Type * bool -> bool
Public Overrides Function IsDefined (attributeType As Type, inherit As Boolean) As Boolean
参数
- attributeType
- Type
自定义属性类型。A custom attribute type.
- inherit
- Boolean
基类中自定义属性的控件继承。Controls inheritance of custom attributes from base classes. 忽略此参数。This parameter is ignored.
返回
如果定义了指定的自定义属性类型,则为 true;否则为 false。true if the specified custom attribute type is defined; otherwise, false.
例外
目前尚不支持此方法。This method is not currently supported. 你可以使用 GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) 检索构造函数并在返回的 ConstructorInfo 上调用 IsDefined(Type, Boolean)。You can retrieve the constructor using GetConstructor(BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) and call IsDefined(Type, Boolean) on the returned ConstructorInfo.
