How do you clear a WPF RichTextBox?
提问by OmniOwl
Whenever I do richtextbox1.Clear()it says the method doesn't exist. And it's pretty much the only solution I get, everywhere I go.
每当我这样做时，richtextbox1.Clear()都会说该方法不存在。无论我走到哪里，这几乎都是我得到的唯一解决方案。
I've tried looking for a Textproperty, and I've tried to look through the Documentproperty as well, but to no avail.
我试过寻找Text房产，我也试过查看Document房产，但无济于事。
What I am missing? The box needs to be cleared, like you can do with a textbox.Clear()call.
我缺少什么？需要清除该框，就像您可以textbox.Clear()拨打电话一样。
