DivisionUnit.RecognitionString 属性

项目
10/28/2008

获取 DivisionUnit 对象中 Strokes 集合的已识别文本。

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

语法

声明
Public ReadOnly Property RecognitionString As String
用法
Dim instance As DivisionUnit
Dim value As String

value = instance.RecognitionString

public string RecognitionString { get; }

public:
property String^ RecognitionString {
    String^ get ();
}

/** @property */
public String get_RecognitionString()

public function get RecognitionString () : String

属性值

类型：System.String
DivisionUnit 对象中 Strokes 集合的已识别文本。

备注

RecognitionString 属性对于绘制元素返回 null。

下表描述了每种类型 DivisionUnit 对象的已识别文本。

DivisionUnit 类型	RecognitionString 值
Segment	识别段的最佳备选项。
Line	行中每个识别段的 RecognizedText，由空格分隔。
Paragraph	段落中每一行的 RecognizedText，由换行符分隔。
Drawing	nullnull 引用（在 Visual Basic 中为 Nothing）

RecognitionString 属性与 DivisionUnit.ToString 方法返回相同的字符串。

示例

此 C# 示例创建一个 Divider 对象 theDivider，该对象包含 Strokes 集合 theStrokes，并使用 RecognizerContext 对象 theRecognizerContext。将调用 Divide 方法以获取分析结果 theResult 的快照。将调用 ResultByType 方法，调用时将 divisionType 参数设置为一个 InkDivisionType 枚举 Line，以检索 theResult 中的所有行单元。对于集合中的每一行 theLine，将检索 DivisionType、Strokes、RecognitionString 和 Transform 属性。

// Create the Divider and assign a Strokes collection to it.
Divider theDivider = new Divider(theStrokes, theRecognizerContext);

// Retrieve the analysis result, and divide the result by line.
DivisionResult theResult = theDivider.Divide();
DivisionUnits theDivisionUnits =
    theResult.ResultByType(InkDivisionType.Line);
foreach (DivisionUnit theLine in theDivisionUnits)
{
    // For each line element in the collection
    // retrieve the division type, the strokes,
    // the recognition string, and the rotation transform.
    InkDivisionType theDivisionType = theLine.DivisionType;
    Strokes elementStrokes = theLine.Strokes;
    string theRecognitionString = theLine.RecognitionString;
    System.Drawing.Drawing2D.Matrix theInkTransform =
        theLine.Transform;
}
