DivisionUnits.GetEnumerator 方法

2008-11-04

返回一个对象，该对象实现 System.Collections.IEnumerator 接口并可以循环访问 DivisionUnits 集合中的 DivisionUnit 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 DivisionUnits..::.InkDivisionUnitsEnumerator
用法
Dim instance As DivisionUnits
Dim returnValue As DivisionUnits..::.InkDivisionUnitsEnumerator

returnValue = instance.GetEnumerator()

public DivisionUnits..::.InkDivisionUnitsEnumerator GetEnumerator()

public:
DivisionUnits..::.InkDivisionUnitsEnumerator^ GetEnumerator()

public DivisionUnits..::.InkDivisionUnitsEnumerator GetEnumerator()

public function GetEnumerator() : DivisionUnits..::.InkDivisionUnitsEnumerator

返回值

类型：Microsoft.Ink.DivisionUnits.InkDivisionUnitsEnumerator
返回一个对象，该对象实现 System.Collections.IEnumerator 接口并可以循环访问 DivisionUnits 集合中的 DivisionUnit 对象。

示例

下面的示例通过两种方式演示如何循环访问 DivisionUnits 集合并获取该集合中包含的每个 DivisionUnit 对象的已识别文本。DivisionUnits 集合由 DivisionResult.ResultByType 方法返回。

在此示例中，将获取 DivisionUnits 集合的 System.Collections.IEnumerator，并用于枚举该集合的每个项。

Dim theRecognizedText As ArrayList = New ArrayList()
Dim theDivisionUnits As DivisionUnits = theDivisionResult.ResultByType(InkDivisionType.Paragraph)
Dim iEnum As System.Collections.IEnumerator = theDivisionUnits.GetEnumerator()
iEnum.Reset()
While iEnum.MoveNext()
    Dim theDivisionUnit As DivisionUnit = DirectCast(iEnum.Current, DivisionUnit)
    theRecognizedText.Add(theDivisionUnit.RecognitionString)
End While

ArrayList theRecognizedText = new ArrayList();
DivisionUnits theDivisionUnits = theDivisionResult.ResultByType(InkDivisionType.Paragraph);
System.Collections.IEnumerator iEnum = theDivisionUnits.GetEnumerator();
iEnum.Reset();
while (iEnum.MoveNext())
{
    DivisionUnit theDivisionUnit = (DivisionUnit)iEnum.Current;
    theRecognizedText.Add(theDivisionUnit.RecognitionString);
}

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。

Dim theRecognizedText As ArrayList = New ArrayList()
Dim theDivisionUnits As DivisionUnits = theDivisionResult.ResultByType(InkDivisionType.Paragraph)
For Each theDivisionUnit As DivisionUnit In theDivisionUnits
    theRecognizedText.Add(theDivisionUnit.RecognitionString)
Next

ArrayList theRecognizedText = new ArrayList();
DivisionUnits theDivisionUnits = theDivisionResult.ResultByType(InkDivisionType.Paragraph);
foreach (DivisionUnit theDivisionUnit in theDivisionUnits)
{
    theRecognizedText.Add(theDivisionUnit.RecognitionString);
}
