获取 Recognizer 对象的功能。

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

语法

声明
Public ReadOnly Property Capabilities As RecognizerCapabilities
用法
Dim instance As Recognizer
Dim value As RecognizerCapabilities

value = instance.Capabilities

public RecognizerCapabilities Capabilities { get; }

public:
property RecognizerCapabilities Capabilities {
    RecognizerCapabilities get ();
}

/** @property */
public RecognizerCapabilities get_Capabilities()

public function get Capabilities () : RecognizerCapabilities

属性值

类型：Microsoft.Ink.RecognizerCapabilities
定义识别器 功能的值。

备注

识别器的功能是在 RecognizerCapabilities 枚举中定义的，这些功能包括识别器是否支持字符自动完成；是否支持自由输入、行输入或框式输入，等等。有关识别器功能的完整列表，请参见 RecognizerCapabilities 枚举。

若要确定识别器是否具有某项特定功能，请使用按位比较运算符检查确认是否具有此项功能。有关按位比较运算原理的更多信息，请参见 And Operator（“与”运算符）。

示例

此示例中，将支持德语（语言 ID 1031）、RecognizerCapabilities 功能 LinedInput 以及 ConfidenceLevel 的第一个 Recognizer 分配给选定的 Recognizer 对象变量。

Dim selectedRecognizer As Recognizer = Nothing
Dim allRecognizers As Recognizers = New Recognizers()
For Each oneReco As Recognizer In allRecognizers
    ' if we haven't found the one we want yet
    If Not selectedRecognizer Is Nothing Then
        ' if supports LinedInput
        If (oneReco.Capabilities And RecognizerCapabilities.LinedInput) <> 0 Then
            For Each langID As Short In oneReco.Languages
                ' if supports German (1031)
                If langID = 1031 Then
                    For Each propertyGuid As Guid In oneReco.SupportedProperties
                        ' if supports ConfidenceLevel
                        If propertyGuid = RecognitionProperty.ConfidenceLevel Then
                            ' assign selected
                            selectedRecognizer = oneReco
                        End If
                    Next
                End If
            Next
        End If
    End If
Next

Recognizer selectedRecognizer = null;
Recognizers allRecognizers = new Recognizers();
foreach (Recognizer oneReco in allRecognizers)
{
    // if we haven't found the one we want yet
    if (null == selectedRecognizer)
    {
        // if supports LinedInput
        if ((oneReco.Capabilities & RecognizerCapabilities.LinedInput) != 0)
        {
            foreach (short langID in oneReco.Languages)
            {
                // if supports German (1031)
                if (langID == 1031)
                {
                    foreach (Guid propertyGuid in oneReco.SupportedProperties)
                    {
                        // if supports ConfidenceLevel
                        if (propertyGuid == RecognitionProperty.ConfidenceLevel)
                        {
                            // assign selected
                            selectedRecognizer = oneReco;
                        }
                    }
                }
            }
        }
    }
