Example page minor html entity error

[louis297]

In the "Empty Block Statements" part of the "example" page of the official website, in the first if statement as:

if (csdocument.RootElement != null && !csdocument.RootElement.Generated)

the 2 "&" are not translated to "&" properly

sorry the '&' + 'amp;' entity is properly translated in the github page, pls check the official website
