如何从文本中的给定位置获取字符的颜色？

Question

I basically want to check whether a character in a given position in a text is a certain color. For example

if(character.inAposition == blue){
   change characters color
}

that's how I initially change the text color

TextPointer start = position.GetPositionAtOffset(indexInRun);
TextPointer end = start.GetPositionAtOffset(word.Length);
TextRange rangeText = new TextRange(start, end);
rangeText.ApplyPropertyValue(TextElement.ForegroundProperty, Brushes.Blue);

where indexInRun is the starting index of any substring that matches "word"

Answer 1

You cant check a character. you can check a Run element of the RichTextBox Inlines collection. But you have to check if it really is a Run or something else like a complete TextBlock, or Image, etc.
