Examples

The following example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code translates an HTML color name to a Color structure, and then uses that color to fill a rectangle.

public:
   void FromHtml_Example( PaintEventArgs^ e )
   {
      // Create a string representation of an HTML color.
      String^ htmlColor = "Blue";

      // Translate htmlColor to a GDI+ Color structure.
      Color myColor = ColorTranslator::FromHtml( htmlColor );

      // Fill a rectangle with myColor.
      e->Graphics->FillRectangle( gcnew SolidBrush( myColor ), 0, 0, 100, 100 );
   }

public void FromHtml_Example(PaintEventArgs e)
{
    // Create a string representation of an HTML color.
    string htmlColor = "Blue";
             
    // Translate htmlColor to a GDI+ Color structure.
    Color myColor = ColorTranslator.FromHtml(htmlColor);
             
    // Fill a rectangle with myColor.
    e.Graphics.FillRectangle( new SolidBrush(myColor), 0, 0, 
        100, 100);
}

Public Sub FromHtml_Example(ByVal e As PaintEventArgs)

    ' Create a string representation of an HTML color.
    Dim htmlColor As String = "Blue"

    ' Translate htmlColor to a GDI+ Color structure.
    Dim myColor As Color = ColorTranslator.FromHtml(htmlColor)

    ' Fill a rectangle with myColor.
    e.Graphics.FillRectangle(New SolidBrush(myColor), 0, 0, 100, 100)
End Sub
