在WPF文本框中添加“＆”

Question

I have a WPF form, for some reason ONLY '&' character within string cannot be compiled with.

<TextBox>=948&showtree=1</TextBox> <!--Error due to char &-->

I have tried: <TextBox Text = @"=948&showtree=1"/> yet, same result.

I have tried adding "!@#$%^*()_+" it also only happens with '&' . What is so special about '&' and how to overcome this problem within xaml ?

I could add it in .cs file but I want to know why did this occurred.

Answer 1

“＆”号是XML中其他代码之前的特殊字符-要使用一个，您需要将用于＆号的代码用于&

<TextBox>=948&amp;showtree=1</TextBox>

Answer 2

& is a special character in XML, which needs to be specified as & , just like < for < and > for > .

So your line should read:

<TextBox>=948&amp;showtree=1</TextBox>

Answer 3

You need to encode the ampersand.

Have you tried & ?
