FlowDocument的运行保持与下

Question

在FlowDocument的我怎么能跟上未来
当文本换行，我不希望这两个运行之间的换行符

Run runMinus = new Run(); 
runMinus.Text = " -"; 
runMinus.Background = brushMinus; 
pargraph.Inlines.Add(runMinus); 
Run run = new Run(); 
run.Text = "sample"; 
run.Background = brushParen; 
pargraph.Inlines.Add(run); 

Answer 1

明白了零宽度NBSP工作（非-breaking space）

run.Text = " –\uFEFF";
