Examples

The following code example demonstrates how to use the ConvertToString method. This example is designed to be used with Windows Forms. Paste this code into a form and call the ShowColorConverter method when handling the form's Paint event, passing e as PaintEventArgs.

void ShowColorConverter( PaintEventArgs^ e )
{
   Color myColor = Color::PaleVioletRed;
   
   // Create the ColorConverter.
   System::ComponentModel::TypeConverter^ converter = System::ComponentModel::TypeDescriptor::GetConverter( myColor );
   String^ colorAsString = converter->ConvertToString( Color::PaleVioletRed );
   e->Graphics->DrawString( colorAsString, this->Font, Brushes::PaleVioletRed, 50.0F, 50.0F );
}

private void ShowColorConverter(PaintEventArgs e)
{

    Color myColor = Color.PaleVioletRed;

    // Create the ColorConverter.
    System.ComponentModel.TypeConverter converter = 
        System.ComponentModel.TypeDescriptor.GetConverter(myColor);

    string colorAsString = converter.ConvertToString(Color.PaleVioletRed);
    e.Graphics.DrawString(colorAsString, this.Font,
        Brushes.PaleVioletRed, 50.0F, 50.0F);
}

Private Sub ShowColorConverter(ByVal e As PaintEventArgs)

    Dim myColor As Color = Color.PaleVioletRed

    ' Create the ColorConverter.
    Dim converter As System.ComponentModel.TypeConverter = _
       System.ComponentModel.TypeDescriptor.GetConverter(myColor)

    Dim colorAsString As String = _
        converter.ConvertToString(Color.PaleVioletRed)
    e.Graphics.DrawString(colorAsString, Me.Font, _
        Brushes.PaleVioletRed, 50.0F, 50.0F)
End Sub

Remarks

When converting from a string to a Color the ColorConverter expects the unqualified color name; otherwise, an exception will occur in the conversion process. For example, you should pass "Blue", not "System.Drawing.Color.Blue" or "Color.Blue", to the ConvertFrom method.

Constructors
