title: Equivalent VBs -> C# : Eval and Execute
body: <p>I try to convert a part of code from VBScript to C#. 
  I have these lines : </p>
  
  <pre><code>string replacementMatch = ....;
  </code></pre>
  
  <p>...</p>
  
  <pre><code>replacementMatch = Eval(replacementMatch);
  </code></pre>
  
  <p>OR </p>
  
  <pre><code>Execute(replacementMatch);
  </code></pre>
  
  <p>I can't find the equivalent in C#.</p>
