title: Excel formula with double quote with C#
body: <p>I would like to write a formula in a Excel cell with SpreadSightLight in C#.
  I have a following formula in excel</p>
  
  <pre><code>=COUNTIFS(Sheet2!E:E, D2, Shet2!A:A, "&gt;0")
  </code></pre>
  
  <p>In the code it looks </p>
  
  <pre><code>"=COUNTIFS({0}!E:E,{1},{0}!A:A ,\"&gt;0\")";  
  </code></pre>
  
  <p>I save the file from the code, but when i try to open the file Excel (2013) gives error message and the formula is removed</p>
  
  <blockquote>
    <p>Removed Records: Formula from /xl/worksheets/sheet3.xml part</p>
  </blockquote>
  
  <p>and the sheet3.xml contains the following line</p>
  
  <pre><code>COUNTIFS(Sheet2!E:E, D2, Sheet2!A:A ,&amp;quot;&amp;gt;0&amp;quot;)
  </code></pre>
  
  <p>I tried the verbatim string and the char(34) solutions also but causes the same error.</p>
  
  <p>How can I solve this problem?
  Thanks in advance.</p>
