FlowDocument的運行保持與下

Question

在FlowDocument的我怎麼能跟上未來
當文本換行，我不希望這兩個運行之間的換行符

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

明白了零寬度NBSP工作（非-breaking space）

run.Text = " –\uFEFF";
