SortedList<TKey,TValue>.IDictionary.Values 属性

定义

获取一个 ICollection,它包含 IDictionary 中的值。Gets an ICollection containing the values in the IDictionary.

property System::Collections::ICollection ^ System::Collections::IDictionary::Values { System::Collections::ICollection ^ get(); };
System.Collections.ICollection System.Collections.IDictionary.Values { get; }
 ReadOnly Property Values As ICollection Implements IDictionary.Values

属性值

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IDictionary.Values System.Collections.IDictionary接口的属性与结合SortedList<TKey,TValue>使用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, System.Collections.IDictionary接口的枚举器将DictionaryEntry返回对象, KeyValuePair<TKey,TValue>而不是对象。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IDictionary.Add方法提供的更大示例,包括输出。The code example is part of a larger example, including output, provided for the IDictionary.Add method.

        //
        IDictionary openWith = new SortedList<string, string>();

        // Add some elements to the sorted list. There are no 
        // duplicate keys, but some of the values are duplicates.
        // IDictionary.Add throws an exception if incorrect types
        // are supplied for key or value.
        openWith.Add("txt", "notepad.exe");
        openWith.Add("bmp", "paint.exe");

    Public Shared Sub Main() 

        ' Create a new sorted list of strings, with string keys,
        ' and access it using the IDictionary interface.

        openWith.Add("rtf", "wordpad.exe")
// To get the values alone, use the Values property.
ICollection icoll = openWith.Values;

// The elements of the collection are strongly typed
// with the type that was specified for values,
// even though the ICollection interface is not strongly
// typed.
Console.WriteLine();
foreach( string s in icoll )
{
    Console.WriteLine("Value = {0}", s);
}
' To get the values alone, use the Values property.
Dim icoll As ICollection = openWith.Values

' The elements of the collection are strongly typed
' with the type that was specified for sorted list values,
' even though the ICollection interface is not strongly
' typed.
Console.WriteLine()
For Each s As String In  icoll
    Console.WriteLine("Value = {0}", s)
Next s
// When you use foreach to enumerate sorted list elements
// with the IDictionary interface, the elements are retrieved
// as DictionaryEntry objects instead of KeyValuePair objects.
Console.WriteLine();
foreach( DictionaryEntry de in openWith )
{
    Console.WriteLine("Key = {0}, Value = {1}", 
        de.Key, de.Value);
}
' When you use foreach to enumerate sorted list elements
' with the IDictionary interface, the elements are retrieved
' as DictionaryEntry objects instead of KeyValuePair objects.
Console.WriteLine()
For Each de As DictionaryEntry In openWith
    Console.WriteLine("Key = {0}, Value = {1}", _
        de.Key, de.Value)
Next 
    }
}

    End Sub

End Class

注解

ICollection值的顺序与SortedList<TKey,TValue>中的顺序相同。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.
