Gets or sets an array of bytes that specify the Region object.
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()
Byte[]
An array of bytes that specify the Region object.
- The following example is designed for use with Windows Forms, and it requires PaintEventArgs
e
, which is a parameter of thePaint
event handler. The code example demonstrates how to use the Data from one RegionData object to set the Data for another RegionData.
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.
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();
region2.Dispose();
// Call ExcludeClip passing in the third region.
e.Graphics.ExcludeClip(region3);
// Fill in the client rectangle.
e.Graphics.FillRectangle(Brushes.Red, this.ClientRectangle);
region3.Dispose();
}
Private Sub DemonstrateRegionData2(ByVal e As PaintEventArgs)

Dim region1 As New Region(New Rectangle(10, 10, 100, 100))
