For readability, you are much better off using the verbatim string literal:

A verbatim string literal consists of an @ character followed by a double-quote character, zero or more characters, and a closing double-quote character.... A verbatim string literal may span multiple lines.

var qry = @"SELECT NewsArticle.NewsId, NewsArticle.NewsDate, NewsArticle.NewsTitle,
          NewsArticle.NewsText NewsArticle.NewsPictureUrl, NewsArticle.Newslink  NewsArticle.IsVisible,
          UserProfile.Membername, UserProfile.Firstname  UserProfile.Lastname, NewsCategory.CategoryName
          FROM  NewsArticle
          INNER JOIN UserProfile  ON UserProfile.UserId = Newsarticle.UserId
          INNER JOIN Newscategory  ON Newscategory.CategoryId = Newsarticle.CategoryId
          WHERE Newsarticle.Isvisible = 1
          ORDER BY Newsarticle.Newsdate DESC";
