StateManagedCollection.IList.Contains(Object) 方法
定义
确定 StateManagedCollection 集合中是否包含特定值。Determines whether the StateManagedCollection collection contains a specific value.
virtual bool System.Collections.IList.Contains(System::Object ^ value) = System::Collections::IList::Contains;
bool IList.Contains (object value);
abstract member System.Collections.IList.Contains : obj -> bool
override this.System.Collections.IList.Contains : obj -> bool
Function Contains (value As Object) As Boolean Implements IList.Contains
参数
- value
- Object
要在 object 中定位的 StateManagedCollection。The object to locate in the StateManagedCollection.
返回
如果在 StateManagedCollection 中找到对象,则为 true;否则为 false。true if the object is found in the StateManagedCollection; otherwise, false. 如果为值参数传递 null,则返回 false。If null is passed for the value parameter, false is returned.
实现
注解
OnValidate调用方法以在 value 检查集合之前进行验证。The OnValidate method is called to validate value before the collection is checked.
