title: Need example how to build SQL database in C#
body: <p>Need example how to create new local database and a connection string, if possible with a using statement.</p>
  
  <p>There should be 1 table and the data that I want to put in there are unique words length 2-50 lowercase characters, and thy can contain "a-zõäöüšž", ordered by ascending.</p>
  
  <p>There are 2 actions I want to do with that:</p>
  
  <ol>
  <li>Put HashSet of string called words in</li>
  <li>Get HashSet of string called words that are specific length </li>
  </ol>
  
  <p>Optionally, I could use an example how to reduce amount of answers given by Get, by telling what letter x must be or what it can not be in a specific location within length of word.</p>
  
  <p><strong>Edit</strong> Found my answer by Google.</p>
