SortedList<TKey,TValue>.IDictionary.Values 属性

property System::Collections::ICollection ^ System::Collections::IDictionary::Values { System::Collections::ICollection ^ get(); };

System.Collections.ICollection System.Collections.IDictionary.Values { get; }

member this.System.Collections.IDictionary.Values : System.Collections.ICollection

 ReadOnly Property Values As ICollection Implements IDictionary.Values

属性值

ICollection

一个 ICollection，它包含 IDictionary 中的值。An ICollection containing the values in the IDictionary.

实现

示例

下面的代码示例演示如何将接口的 IDictionary.Values 属性 System.Collections.IDictionary 与结合使用 SortedList<TKey,TValue> 来列出已排序列表中的值。The following code example shows how to use the IDictionary.Values property of the System.Collections.IDictionary interface with a SortedList<TKey,TValue>, to list the values in the sorted list. 该示例还演示如何枚举排序列表中的键/值对;请注意，接口的枚举器将 System.Collections.IDictionary 返回 DictionaryEntry 对象，而不是 KeyValuePair<TKey,TValue> 对象。The example also shows how to enumerate the key/value pairs in the sorted list; note that the enumerator for the System.Collections.IDictionary interface returns DictionaryEntry objects rather than KeyValuePair<TKey,TValue> objects.

此代码示例摘自为方法提供的更大示例，包括输出 IDictionary.Add 。The code example is part of a larger example, including output, provided for the IDictionary.Add method.

        // Add some elements to the sorted list. There are no

        // IDictionary.Add throws an exception if incorrect types
        // are supplied for key or value.

注解

中值的顺序与中的 ICollection 顺序相同 SortedList<TKey,TValue> 。The order of the values in the ICollection is the same as the order in the SortedList<TKey,TValue>.

检索此属性的值的运算复杂度为 O(1)。Retrieving the value of this property is an O(1) operation.
