public OrderedDictionary();

Public Sub New ()

示例

下面的代码示例演示集合的 OrderedDictionary 创建和填充。此代码是可在以下位置 OrderedDictionary查看的较大代码示例的一部分。

// Creates and initializes a OrderedDictionary.
OrderedDictionary myOrderedDictionary = new OrderedDictionary();
myOrderedDictionary.Add("testKey1", "testValue1");
myOrderedDictionary.Add("testKey2", "testValue2");
myOrderedDictionary.Add("keyToDelete", "valueToDelete");
myOrderedDictionary.Add("testKey3", "testValue3");

ICollection keyCollection = myOrderedDictionary.Keys;
ICollection valueCollection = myOrderedDictionary.Values;

// Display the contents using the key and value collections
DisplayContents(keyCollection, valueCollection, myOrderedDictionary.Count);

' Creates and initializes a OrderedDictionary.
Dim myOrderedDictionary As New OrderedDictionary()
myOrderedDictionary.Add("testKey1", "testValue1")
myOrderedDictionary.Add("testKey2", "testValue2")
myOrderedDictionary.Add("keyToDelete", "valueToDelete")
myOrderedDictionary.Add("testKey3", "testValue3")

Dim keyCollection As ICollection = myOrderedDictionary.Keys
Dim valueCollection As ICollection = myOrderedDictionary.Values

' Display the contents Imports the key and value collections
DisplayContents( _
    keyCollection, valueCollection, myOrderedDictionary.Count)

注解

比较器确定两个键是否相等。集合中的每个键都必须是唯一 OrderedDictionary 的。默认比较器是密钥的 Object.Equals实现。
