C# WPF Textblock different font color per line

问题:

I am trying to make each line of text on a WPF textblock display in a different color. I have the following code which makes the entire block's font color purple because that's the last color it's set to. How can I make it so each potion is displayed in a different color?

    private void btnShowPotions_Click(object sender, RoutedEventArgs e) {

        tbPotionInfo.Foreground = Brushes.Green;
        tbPotionInfo.Text = smallPotion.Name + "(" + smallPotion.AffectValue + ")\r\n";
        tbPotionInfo.Foreground = Brushes.Blue;
        tbPotionInfo.Text += mediumPotion.Name + "(" + mediumPotion.AffectValue + ")\r\n";
        tbPotionInfo.Foreground = Brushes.Red;
        tbPotionInfo.Text += largePotion.Name + "(" + largePotion.AffectValue + ")\r\n";
        tbPotionInfo.Foreground = Brushes.Purple;
        tbPotionInfo.Text += extremePotion.Name + "(" + extremePotion.AffectValue + ")\r\n";
    }

You can make use of Run.

Here is the sample of how to use the Run

Run run = new Run(smallPotion.Name + "(" + smallPotion.AffectValue + ")\r\n");
run.Foreground = Brushes.Green;
tbPotionInfo.Inlines.Add(run);   

run = new Run(mediumPotion.Name + "(" + mediumPotion.AffectValue + ")\r\n");
run.Foreground = Brushes.Blue;
tbPotionInfo.Inlines.Add(run);        
...

Haven't verified but I hope it will help you.

Use textblock like this

<TextBlock>
      <TextBlock Name="tbSmallPotion" Foreground="Green"/
      <TextBlock Text="tbMediumPotion"Foreground="Blue"/>
 </TextBlock>

and set the values

tbSmallPotion.Text = smallPotion.Name + "(" + smallPotion.AffectValue + ")\r\n";
tbMediumPotion.Text = mediumPotion.Name + "(" + mediumPotion.AffectValue + ")\r\n";
