.NET Framework クラス ライブラリ リファレンス

RegionData.Data プロパティ

Region オブジェクトを指定するバイトの配列を取得または設定します。

名前空間: System.Drawing.Drawing2D
アセンブリ: System.Drawing (system.drawing.dll 内)
構文

Visual Basic (宣言)

Public Property Data As
 Byte()

Visual Basic (使用法)

Dim instance As RegionData
Dim value As Byte()

value = instance.Data

instance.Data = value

C#

public byte[] Data { get; set;
 }

C++

public:
property array<unsigned char>^ Data {
    array<unsigned char>^ get ();
    void set (array<unsigned char>^
 value);
}

J#

/** @property */
public byte[] get_Data ()

/** @property */
public void set_Data (byte[] value)

JScript

public function get Data
 () : byte[]

public function set Data
 (value : byte[])

プロパティ値
Region オブジェクトを指定するバイトの配列。

使用例

• 次の例は、Windows フォームでの使用を意図してデザインされており、Paint イベント ハンドラのパラメータである PaintEventArgse が必要です。ある RegionData オブジェクトの Data を使用して、別の RegionData の Data を設定する方法を次のコード例に示します。

Visual Basic

Private Sub DemonstrateRegionData2(ByVal
 e As PaintEventArgs)

    'Create a simple region.
    Dim region1 As New Region(New
 Rectangle(10, 10, 100, 100))

    ' Extract the region data.
    Dim region1Data As System.Drawing.Drawing2D.RegionData
 = region1.GetRegionData
    Dim data1() As Byte
    data1 = region1Data.Data

    ' Create a second region.
    Dim region2 As New Region

    ' Get the region data for the second region.
    Dim region2Data As System.Drawing.Drawing2D.RegionData
 = region2.GetRegionData()

    ' Set the Data property for the second region to the Data from the
 first region.
    region2Data.Data = data1

    ' Construct a third region using the modified RegionData of the
 second region.
    Dim region3 As New Region(region2Data)

    ' Dispose of the first and second regions.
    region1.Dispose()
    region1.Dispose()

    ' Call ExcludeClip passing in the third region.
    e.Graphics.ExcludeClip(region3)

    ' Fill in the client rectangle.
    e.Graphics.FillRectangle(Brushes.Red, Me.ClientRectangle)

    region3.Dispose()

End Sub

C#

private void DemonstrateRegionData2(PaintEventArgs
 e)
{

    //Create a simple region.
    Region region1 = new Region(new Rectangle(10,
 10, 100, 100));

    // Extract the region data.
    System.Drawing.Drawing2D.RegionData region1Data = region1.GetRegionData();
    byte[] data1;
    data1 = region1Data.Data;

    // Create a second region.
    Region region2 = new Region();

    // Get the region data for the second region.
    System.Drawing.Drawing2D.RegionData region2Data = region2.GetRegionData();

    // Set the Data property for the second region to the Data from
 the first region.
    region2Data.Data = data1;

    // Construct a third region using the modified RegionData of the
 second region.
    Region region3 = new Region(region2Data);

    // Dispose of the first and second regions.
    region1.Dispose();
    region1.Dispose();
