Comparing string to background color

Question

private void Button_Click(object sender, RoutedEventArgs e){
    Button btn = (Button)sender;
    if(/*insert if condition here*/)
    {
        cntr = 1;
        void1();
    }
}

I'm currently developing a C# Windows store app. I have a TextBlock that can have a text of either Red, Orange, Yellow, Green, Blue, Indigo or Violet. I also have seven buttons with different background colors. Now, I want to check if the text of my TextBlock matches the backgound color of the Button clicked.

Answer 1

Use a BrushConverter instance to convert the text of the text block into a Brush object, then compare that brush against the button's background.

Some example XAML:

<StackPanel>
    <TextBlock x:Name="MyTextBlock" Text="Red" />
    <Button Content="Blue" Background="Blue" Click="OnColorButtonClick" />
    <Button Content="Red" Background="Red" Click="OnColorButtonClick" />
    <Button Content="Green" Background="Green" Click="OnColorButtonClick" />
    <Button Content="Yellow" Background="Yellow" Click="OnColorButtonClick" />
</StackPanel>

...and the button handler code (note that all of the buttons in the example use the same click handler):

private void OnColorButtonClick(object sender, RoutedEventArgs e)
{
    var converter = new BrushConverter();
    var textblockBrush =
        converter.ConvertFromString(MyTextBlock.Text) as Brush;
    var button = (Button) sender;
    if (button.Background == textblockBrush)
    {
        // text of my TextBlock matches the backgound color of the Button clicked
    }
}
