Wpf, how do I save overlined text to a string

i have a textblock that overlines a string, is there a way to save the string inside the textblock with the overline to another string.
My end goal is to be able to stack overlines on top of eachother, im trying to make a boolean expression writer and i cant really find anything on how to draw stacked lines on top of text.

What I have tried:

C#

private void setExpressionSegment(parentControl x)
        {
            if (x.GetType() == typeof(OUTPUT)) return;
            if (x.GetType() == typeof(AND))
            {
                x.boolean = "(" + x.inp1Boolean + "." + x.inp2Boolean + ")";
                expressionBox.TextDecorations = null;
            }
            else if (x.GetType() == typeof(OR))
            {
                x.boolean = "(" + x.inp1Boolean + "+" + x.inp2Boolean + ")";
                expressionBox.TextDecorations = null;
            }
            else if (x.GetType() == typeof(XOR))
            {
                x.boolean = "(" + x.inp1Boolean + "⊕" + x.inp2Boolean + ")";
                expressionBox.TextDecorations = null;
            }
            else if (x.GetType() == typeof(NAND))
            {
                x.boolean = "!(" + x.inp1Boolean + "." + x.inp2Boolean + ")";
                expressionBox.TextDecorations = TextDecorations.OverLine;
            }
            else if (x.GetType() == typeof(NOR))
            {
                x.boolean = "!(" + x.inp1Boolean + "+" + x.inp2Boolean + ")";
                expressionBox.TextDecorations = TextDecorations.OverLine;
            }
            else if (x.GetType() == typeof(NOT))
            {
                x.boolean = "!" + x.inp2Boolean;
                expressionBox.TextDecorations = TextDecorations.OverLine;
            }
            expressionBox.Text = x.boolean;
        }

if i could save the overlined text to a string then i could add it back to the textblock and overline it, just not sure how.

Solution 1

You can create your own markup when you save the text, and remove it when you restore. e.g.

Plain: text
Overline: .ol text

C#

string s = "text";
s = ".ol " + s;

if ( s.StartsWith( ".ol " ) ) {
   s = s.Substring( 4 );
   // etc.
}
