Definitie
Belangrijk
Bepaalde informatie heeft betrekking op een voorlopige productversie die aanzienlijk kan worden gewijzigd voordat deze wordt uitgebracht. Microsoft biedt geen enkele expliciete of impliciete garanties met betrekking tot de informatie die hier wordt verstrekt.
Hiermee haalt u een matrix van bytes op die het object opgeven of stelt u deze Region in.
public:
property cli::array <System::Byte> ^ Data { cli::array <System::Byte> ^ get(); void set(cli::array <System::Byte> ^ value); };
public byte[] Data { get; set; }
member this.Data : byte[] with get, set
Public Property Data As Byte()
Waarde van eigenschap
Een matrix van bytes die het Region object opgeven.
Voorbeelden
- Het volgende voorbeeld is ontworpen voor gebruik met Windows Forms en vereist PaintEventArgs
e, een parameter van dePaintgebeurtenis-handler. In het codevoorbeeld ziet u hoe u het van het Data ene RegionData object gebruikt om de Data voor het andere RegionDatain te stellen.
private:
void DemonstrateRegionData2( PaintEventArgs^ e )
{
//Create a simple region.
System::Drawing::Region^ region1 = gcnew System::Drawing::Region( Rectangle(10,10,100,100) );
// Extract the region data.
System::Drawing::Drawing2D::RegionData^ region1Data = region1->GetRegionData();
array<Byte>^data1;
data1 = region1Data->Data;
// Create a second region.
System::Drawing::Region^ region2 = gcnew System::Drawing::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.
System::Drawing::Region^ region3 = gcnew System::Drawing::Region( region2Data );
// Dispose of the first and second regions.
delete region1;
delete region2;
// Call ExcludeClip passing in the third region.
e->Graphics->ExcludeClip( region3 );
// Fill in the client rectangle.
e->Graphics->FillRectangle( Brushes::Red, this->ClientRectangle );
delete region3;
}
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.

// Dispose of the first and second regions.

// Call ExcludeClip passing in the third region.
