語法

'宣告

'用途
Dim instance As RecognitionResult
Dim value As Strokes

public function get Strokes () : Strokes

屬性值

型別：Microsoft.Ink.Strokes
「辨識器」用來產生 RecognitionResult 物件的 Strokes 集合。

備註

根據預設，RecognitionResult 物件不會附加至 Strokes 集合。若要將結果指派至 Strokes 集合，您必須呼叫 RecognitionResult 物件的 SetResultOnStrokes 方法。

範例

在這個範例中，會處理同步辨識以回應使用者動作，例如按一下功能表項目或按鈕。首先，會從與 InkOverlay 物件相關聯的 Strokes 集合指派 RecognizerContext 物件的 Strokes 集合，並檢查筆劃計數。如果 Strokes 集合包含至少一個 Stroke 物件，則辨識程序會先呼叫 Recognize 方法。如果辨識成功，而且 TopConfidence (如果支援的話) 不等於 RecognitionConfidencePoor (亦即，它是 Intermediate 或 Strong)，則會將 TopString 加入至清單方塊以便顯示。

' assign strokes collection from the collected strokes
Me.mRecognizerContext.Strokes = Me.mInkOverlay.Ink.Strokes
' check stroke count. Recognize() will throw exception if no strokes
If (Me.mRecognizerContext.Strokes.Count > 0) Then
    Dim status As RecognitionStatus
    ' perform the recognition
    Dim rResult As RecognitionResult = Me.mRecognizerContext.Recognize(status)
    ' see if the recognizer used supports confidence levels
    Dim rSupportsConfidence As Boolean = RecognizerSupportsConfidence(mRecognizerContext.Recognizer)
    ' check status and TopConfidence (if supported)
    If (RecognitionStatus.NoError = status And _
        ((rSupportsConfidence And _
         rResult.TopConfidence <> RecognitionConfidence.Poor) Or _
         Not rSupportsConfidence)) Then
        listBoxRecognitionResults.Items.Add(rResult.TopString)
    End If
End If

// assign strokes collection from the collected strokes
this.mRecognizerContext.Strokes = this.mInkOverlay.Ink.Strokes;
// check stroke count. Recognize() will throw exception if no strokes
if (this.mRecognizerContext.Strokes.Count > 0)
{
    RecognitionStatus status;
    // perform the recognition
    RecognitionResult rResult = this.mRecognizerContext.Recognize(out status);
    // see if the recognizer used supports confidence levels
    bool rSupportsConfidence = RecognizerSupportsConfidence(mRecognizerContext.Recognizer);
    // check status and TopConfidence (if supported)
    if (RecognitionStatus.NoError == status &&
        ((rSupportsConfidence &&
         rResult.TopConfidence != RecognitionConfidence.Poor) ||
         !rSupportsConfidence))
    {
        listBoxRecognitionResults.Items.Add(rResult.TopString);
    }
}

下列範例說明 Helper 方法，這個方法可用來判斷 Recognizer 是否支援信賴等級。

Private Function RecognizerSupportsConfidence(ByVal pRecognizer As Recognizer) As Boolean
    For Each G As Guid In pRecognizer.SupportedProperties
        If G = RecognitionProperty.ConfidenceLevel Then
            Return True
        End If
    Next
    Return False
End Function

private bool RecognizerSupportsConfidence(Recognizer pRecognizer)
{
    foreach (Guid G in pRecognizer.SupportedProperties)
    {
        if (G == RecognitionProperty.ConfidenceLevel)
        {
            return true;
        }
    }
    return false;
}
