命名空间： System.Windows.Ink
程序集： IAWinFX（在 IAWinFX.dll 中）

语法

声明
Public Function GetStrokeType ( _
    stroke As Stroke _
) As StrokeType
用法
Dim instance As InkAnalyzer
Dim stroke As Stroke
Dim returnValue As StrokeType

returnValue = instance.GetStrokeType(stroke)

public StrokeType GetStrokeType(
    Stroke stroke
)

public:
StrokeType GetStrokeType(
    Stroke^ stroke
)

public StrokeType GetStrokeType(
    Stroke stroke
)

public function GetStrokeType(
    stroke : Stroke
) : StrokeType

参数

stroke
类型：System.Windows.Ink.Stroke
具有给定类型分类的笔画。

返回值

类型：System.Windows.Ink.StrokeType
stroke 的分类。

备注

如果笔画的类型为 System.Windows.Ink.StrokeType 值 Unspecified，则 InkAnalyzer 在墨迹分析过程中对笔画进行分类。否则，InkAnalyzer 使用在笔画上设置的类型。

若要指定或更改笔画类型，请使用 SetStrokeType() 或 SetStrokesType()。

示例

此示例定义 GetStrokeTypesInNode 方法，用于返回 ContextNode 中的所有笔画类型。

' Iterate through the strokes within the context node and add the
' stroke types to a collection.
Dim theStrokeTypes As New System.Collections.ArrayList()
Dim theStroke As Stroke
For Each theStroke In theContextNode.Strokes
    Dim theStrokeType As StrokeType = theInkAnalyzer.GetStrokeType(theStroke)
    If Not theStrokeTypes.Contains(theStrokeType) Then
        theStrokeTypes.Add(theStrokeType)
    End If
Next theStroke

// Iterate through the strokes within the context node and add the
// stroke types to a collection.
System.Collections.ArrayList theStrokeTypes =
    new System.Collections.ArrayList();
foreach (Stroke theStroke in theContextNode.Strokes)
{
    StrokeType theStrokeType =
        theInkAnalyzer.GetStrokeType(theStroke);
    if (!theStrokeTypes.Contains(theStrokeType))
    {
        theStrokeTypes.Add(theStrokeType);
    }
}
