將 AnalysisRegion 的區域限制為其與指定的 AnalysisRegion 未交集的區域部分。

命名空間： System.Windows.Ink
組件： IAWinFX (在 IAWinFX.dll 中)

語法

'宣告
Public Sub Exclude ( _
    regionToExclude As AnalysisRegion _
)
'用途
Dim instance As AnalysisRegion
Dim regionToExclude As AnalysisRegion

instance.Exclude(regionToExclude)

public void Exclude(
    AnalysisRegion regionToExclude
)

public:
void Exclude(
    AnalysisRegion^ regionToExclude
)

public void Exclude(
    AnalysisRegion regionToExclude
)

public function Exclude(
    regionToExclude : AnalysisRegion
)

參數

regionToExclude
型別：System.Windows.Ink.AnalysisRegion
描述要排除之區域的 AnalysisRegion。

備註

如果兩個區域未交集，則這個 AnalysisRegion 會不變。

範例

這個範例會建立兩個 AnalysisRegion 物件，並使用 Intersect、Union 和 Exclude 方法修改物件的區域。

' Create an infinite AnalysisRegion.
Dim theFirstAnalysisRegion As New AnalysisRegion()
' Create a finite AnalysisRegion.
Dim theSecondAnalysisRegion As New AnalysisRegion(New Rect(100, 100, 200, 200))
' Extend an AnalysisRegion using the Union method and an AnalysisRegion.
theFirstAnalysisRegion.Union(theSecondAnalysisRegion)

' Extend an AnalysisRegion using the Union method and a rectangle.
theFirstAnalysisRegion.Union(New Rect(100, 100, 200, 200))

' Restrict an AnalysisRegion using the Intersect method and an AnalysisRegion.
theFirstAnalysisRegion.Intersect(theSecondAnalysisRegion)

' Restrict an AnalysisRegion using the Intersect method and a rectangle.
theFirstAnalysisRegion.Intersect(New Rect(100, 100, 200, 200))

' Modify an AnalysisRegion using the Exclude method and an AnalysisRegion.
theFirstAnalysisRegion.Exclude(theSecondAnalysisRegion)

' Modify an AnalysisRegion using the Exclude method and a rectangle.
theFirstAnalysisRegion.Exclude(New Rect(100, 100, 200, 200))

// Create an infinite AnalysisRegion.
AnalysisRegion theFirstAnalysisRegion =
    new AnalysisRegion();

// Create a finite AnalysisRegion.
AnalysisRegion theSecondAnalysisRegion =
    new AnalysisRegion(
        new Rect(100, 100, 200, 200));

// Extend an AnalysisRegion using the Union method and an AnalysisRegion.
theFirstAnalysisRegion.Union(theSecondAnalysisRegion);

// Extend an AnalysisRegion using the Union method and a rectangle.
theFirstAnalysisRegion.Union(new Rect(100, 100, 200, 200));

// Restrict an AnalysisRegion using the Intersect method and an AnalysisRegion.
theFirstAnalysisRegion.Intersect(theSecondAnalysisRegion);

// Restrict an AnalysisRegion using the Intersect method and a rectangle.
theFirstAnalysisRegion.Intersect(new Rect(100, 100, 200, 200));

// Modify an AnalysisRegion using the Exclude method and an AnalysisRegion.
theFirstAnalysisRegion.Exclude(theSecondAnalysisRegion);

// Modify an AnalysisRegion using the Exclude method and a rectangle.
theFirstAnalysisRegion.Exclude(new Rect(100, 100, 200, 200));
