示例

下面的代码示例演示集合的 OrderedDictionary 修改。 在此示例中，该方法 Clear 用于清空 OrderedDictionary，然后 OrderedDictionary 重新填充该方法。 此代码是可在以下位置 OrderedDictionary查看的较大代码示例的一部分。

// Clear the OrderedDictionary and add new values
myOrderedDictionary.Clear();
myOrderedDictionary.Add("newKey1", "newValue1");
myOrderedDictionary.Add("newKey2", "newValue2");
myOrderedDictionary.Add("newKey3", "newValue3");

// Display the contents of the "new" Dictionary using an enumerator
IDictionaryEnumerator myEnumerator =
    myOrderedDictionary.GetEnumerator();

Console.WriteLine(
    "{0}Displaying the entries of a \"new\" OrderedDictionary.",
    Environment.NewLine);

DisplayEnumerator(myEnumerator);

' Clear the OrderedDictionary and add new values
myOrderedDictionary.Clear()
myOrderedDictionary.Add("newKey1", "newValue1")
myOrderedDictionary.Add("newKey2", "newValue2")
myOrderedDictionary.Add("newKey3", "newValue3")

' Display the contents of the "new" Dictionary Imports an enumerator
Dim myEnumerator As IDictionaryEnumerator = _
    myOrderedDictionary.GetEnumerator()

Console.WriteLine( _
    "{0}Displaying the entries of a 'new' OrderedDictionary.", _
    Environment.NewLine)

DisplayEnumerator(myEnumerator)

注解

调用 Clear 该方法后，该 Count 属性设置为零，并且还会释放对集合元素中其他对象的引用。 由于调用此方法，容量不会更改。
