Special Character Input in XAML

Some special characters cannot be directly entered into attribute strings, such as quotation marks, symbols (&), and angle brackets (<> ). If you want to use this symbol, you must replace it with an equal-price XML string: The quotation mark is & quot;, and the symbol is & amp;, and the <(less than) symbol is & lt; (less than),> (greater than) is & gt; (greater ). Of course, this is only applicable to XML documents.CodeThis problem does not exist when setting properties in.
