11/04/2008

返回一个对象，该对象实现 System.Collections.IEnumerator 接口并可以循环访问 Tablets 集合中的 Tablet 对象。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink（在 Microsoft.Ink.dll 中）

语法

声明
Public Function GetEnumerator As Tablets..::.TabletsEnumerator
用法
Dim instance As Tablets
Dim returnValue As Tablets..::.TabletsEnumerator

returnValue = instance.GetEnumerator()

public Tablets..::.TabletsEnumerator GetEnumerator()

public:
Tablets..::.TabletsEnumerator^ GetEnumerator()

public Tablets..::.TabletsEnumerator GetEnumerator()

public function GetEnumerator() : Tablets..::.TabletsEnumerator

返回值

类型：Microsoft.Ink.Tablets.TabletsEnumerator
返回一个对象，该对象实现 IEnumerator 接口并可以循环访问 Tablets 集合中的 Tablet 对象。

示例

下面的示例演示两种方法，用于循环访问 Tablets 集合 allTablets，并使用附加到系统的每个 Tablet 设备的名称填充 ListBox 对象 listBoxTablets。

此示例获取 Tablets 集合的 IEnumerator。

' Calling the constructor automatically fills the 
' Tablets collection with the available Tablet objects.
Dim allTablets As Tablets = New Tablets()

' clear the list box
Me.listBoxTablets.Items.Clear()

' populate the list box with the name of each tablet
' version using GetEnumerator()
Dim theTabletsEnumerator As IEnumerator = allTablets.GetEnumerator()
While (theTabletsEnumerator.MoveNext())
    Dim T As Tablet = theTabletsEnumerator.Current
    Me.listBoxTablets.Items.Add(T.Name)
End While

// Calling the constructor automatically fills the 
// Tablets collection with the available Tablet objects.
Tablets allTablets = new Tablets();

// clear the list box
this.listBoxTablets.Items.Clear();

// populate the list box with the name of each tablet
// version using GetEnumerator()
IEnumerator theTabletsEnumerator = allTablets.GetEnumerator();
while (theTabletsEnumerator.MoveNext())
{
    Tablet T = (Tablet)theTabletsEnumerator.Current;
    this.listBoxTablets.Items.Add(T.Name);
}

此示例使用 foreach 语句，该语句调用内部代码中的 GetEnumerator 方法，该方法是编译器为支持此语句而生成的。

' Calling the constructor automatically fills the 
' Tablets collection with the available Tablet objects.
Dim allTablets As Tablets = New Tablets()

' clear the list box
Me.listBoxTablets.Items.Clear()

' populate the list box with the name of each tablet
' version using For Each
For Each T As Tablet In allTablets
    Me.listBoxTablets.Items.Add(T.Name)
Next

// Calling the constructor automatically fills the 
// Tablets collection with the available Tablet objects.
Tablets allTablets = new Tablets();

// clear the list box
this.listBoxTablets.Items.Clear();

// populate the list box with the name of each tablet
// version using foreach
foreach (Tablet T in allTablets)
{
    this.listBoxTablets.Items.Add(T.Name);
}
