SortedList<TKey,TValue>.Values 属性

定义

命名空间:

System.Collections.Generic

程序集:

System.Collections.dll

Source:

SortedList.cs

获得一个包含 SortedList<TKey,TValue> 中的值的集合。

public:
 property System::Collections::Generic::IList<TValue> ^ Values { System::Collections::Generic::IList<TValue> ^ get(); };

public System.Collections.Generic.IList<TValue> Values { get; }

member this.Values : System.Collections.Generic.IList<'Value>

Public ReadOnly Property Values As IList(Of TValue)

属性值

IList<TValue>

一个 IList<T>，包含 SortedList<TKey,TValue> 中的值。

示例

此代码示例演示如何使用 Values 属性枚举排序列表中的值，以及如何枚举排序列表中的键和值。

该示例还演示如何使用 Values 属性高效检索值的索引。

此代码示例是为 SortedList<TKey,TValue> 类提供的一个更大示例的一部分。

// To get the values alone, use the Values property.
IList<String^>^ ilistValues = openWith->Values;

// The elements of the list are strongly typed with the
// type that was specified for the SortedList values.
Console::WriteLine();
for each( String^ s in ilistValues )
{
    Console::WriteLine("Value = {0}", s);
}

// The Values property is an efficient way to retrieve
// values by index.
Console::WriteLine("\nIndexed retrieval using the Values " +
    "property: Values[2] = {0}", openWith->Values[2]);

// To get the values alone, use the Values property.
IList<string> ilistValues = openWith.Values;

// The elements of the list are strongly typed with the
// type that was specified for the SortedList values.
Console.WriteLine();
foreach( string s in ilistValues )
{
    Console.WriteLine("Value = {0}", s);
}

// The Values property is an efficient way to retrieve
// values by index.
Console.WriteLine("\nIndexed retrieval using the Values " +
    "property: Values[2] = {0}", openWith.Values[2]);

' To get the values alone, use the Values property.
Dim ilistValues As IList(Of String) = openWith.Values

' The elements of the list are strongly typed with the
' type that was specified for the SortedList values.
Console.WriteLine()
For Each s As String In ilistValues
    Console.WriteLine("Value = {0}", s)
Next s

' The Values property is an efficient way to retrieve
' values by index.
Console.WriteLine(vbLf & "Indexed retrieval using the " & _
    "Values property: Values(2) = {0}", openWith.Values(2))

// To get the values alone, use the Values property.
let ilistValues = openWith.Values;

// The elements of the list are strongly typed with the
// type that was specified for the SortedList values.
Console.WriteLine()
for s in ilistValues do
    printfn $"Value = {s}"

// The Values property is an efficient way to retrieve
// values by index.
printf "\nIndexed retrieval using the Values "
printfn $"property: Values[2] = {openWith.Values[2]}"

// When you use foreach to enumerate list elements,
// the elements are retrieved as KeyValuePair objects.
Console::WriteLine();
for each( KeyValuePair<String^, String^> kvp in openWith )
{
    Console::WriteLine("Key = {0}, Value = {1}",
        kvp.Key, kvp.Value);
}

// When you use foreach to enumerate list elements,
// the elements are retrieved as KeyValuePair objects.
Console.WriteLine();
foreach( KeyValuePair<string, string> kvp in openWith )
{
    Console.WriteLine("Key = {0}, Value = {1}",
        kvp.Key, kvp.Value);
}

' When you use foreach to enumerate list elements,
' the elements are retrieved as KeyValuePair objects.
Console.WriteLine()
For Each kvp As KeyValuePair(Of String, String) In openWith
    Console.WriteLine("Key = {0}, Value = {1}", _
        kvp.Key, kvp.Value)
Next kvp

// When you use foreach to enumerate list elements,
// the elements are retrieved as KeyValuePair objects.
Console.WriteLine()
for kvp in openWith do
    printfn $"Key = {kvp.Key}, Value = {kvp.Value}"

注解

中 IList<T> 值的顺序与 中 SortedList<TKey,TValue>的顺序相同。

返回的 IList<T> 不是静态副本;相反， IList<T> 引用回原始 SortedList<TKey,TValue>中的值。 因此，对 SortedList<TKey,TValue> 的更改将继续反映在 中 IList<T>。

属性返回的 Values 集合提供了一种按索引检索值的有效方法。 访问属性时无需重新生成列表，因为列表只是值的内部数组的包装器。 以下代码演示如何使用 Values 属性对字符串排序列表中的值进行索引检索：

String^ v = mySortedList->Values[3];

string v = mySortedList.Values[3];

Dim v As String = mySortedList.Values(3)

let v = mySortedList.Values[3]

检索此属性的值的运算复杂度为 O(1)。
