项目
11/04/2008

将此 AnalysisRegionBase 的区域限制为它与指定的 AnalysisRegionBase 相交所形成的区域。

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

语法

声明
Public Sub Intersect ( _
    regionToIntersect As AnalysisRegionBase _
)
用法
Dim instance As AnalysisRegionBase
Dim regionToIntersect As AnalysisRegionBase

instance.Intersect(regionToIntersect)

public void Intersect(
    AnalysisRegionBase regionToIntersect
)

public:
void Intersect(
    AnalysisRegionBase^ regionToIntersect
)

public void Intersect(
    AnalysisRegionBase regionToIntersect
)

public function Intersect(
    regionToIntersect : AnalysisRegionBase
)

参数

regionToIntersect
类型：System.Windows.Ink.AnalysisCore.AnalysisRegionBase
要与之相交的区域。

备注

如果两个区域不相交，则新区域为空。

示例

该示例使用 Exclude、Intersect 和 Union 修改现有 AnalysisRegionBase (theFirstAnalysisRegionBase) 的区域。

' Extend an AnalysisRegionBase using the Union method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Union(theSecondAnalysisRegionBase)

' Extend an AnalysisRegionBase using the Union method and a rectangle.
theFirstAnalysisRegionBase.Union(0, 500, 3000, 3500)

' Restrict an AnalysisRegionBase using the Intersect method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Intersect(theSecondAnalysisRegionBase)

' Restrict an AnalysisRegionBase using the Intersect method and a rectangle.
theFirstAnalysisRegionBase.Intersect(1000, 1000, 5000, 5000)

' Restrict an AnalysisRegionBase using the Exclude method and
' an AnalysisRegionBase.
theFirstAnalysisRegionBase.Exclude(theSecondAnalysisRegionBase)

' Modify an AnalysisRegionBase using the Exclude method and a rectangle.
theFirstAnalysisRegionBase.Exclude(1500, 1500, 2500, 2500)

// Extend an AnalysisRegionBase using the Union method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Union(theSecondAnalysisRegionBase);

// Extend an AnalysisRegionBase using the Union method and a rectangle.
theFirstAnalysisRegionBase.Union(0, 500, 3000, 3500);

// Restrict an AnalysisRegionBase using the Intersect method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Intersect(theSecondAnalysisRegionBase);

// Restrict an AnalysisRegionBase using the Intersect method and a rectangle.
theFirstAnalysisRegionBase.Intersect(1000, 1000, 5000, 5000);

// Restrict an AnalysisRegionBase using the Exclude method and
// an AnalysisRegionBase.
theFirstAnalysisRegionBase.Exclude(theSecondAnalysisRegionBase);

// Modify an AnalysisRegionBase using the Exclude method and a rectangle.
theFirstAnalysisRegionBase.Exclude(1500, 1500, 2500, 2500);
