title: Getting Class FullName (including namespace) from Roslyn ClassDeclarationSyntax
body: <p>I've a ClassDeclarationSyntax from a syntax tree in roslyn.
  I read it like this:</p>
  
  <pre><code>var tree = SyntaxTree.ParseText(sourceCode);
  var root = (CompilationUnitSyntax)tree.GetRoot();
  
  var classes = root.DescendantNodes().OfType&lt;ClassDeclarationSyntax&gt;();
  </code></pre>
  
  <p>The identifier only contains the name of the class but no information about the namespace, so the fullType Name is missing. Like "MyClass" but noch "Namespace1.MyClass"</p>
  
  <p>what is the recommended way to get the namespace / FulltypeName of the  Syntax?</p>
