title: Adding a key value pair in a dictionary inside a dictionary
body: <p>I have a dictionary &lt; string,object > which has a mapping of a string and a dictionary &lt; string,int >. How do I add a key value pair in the inside dictionary &lt; string ,int > ?</p>
  
  <pre><code>Dictionary &lt;string,object&gt; dict = new Dictionary &lt;string,object&gt;();
  Dictionary &lt;string,int&gt; insideDict = new Dictionary &lt;string,int&gt;();
  // ad some values in insideDict
  dict.Add("blah",insideDict);
  </code></pre>
  
  <p>So now the dict has a dictionary mapped with a string.Now I want to separately add values to the insideDict.
  I tried </p>
  
  <pre><code>dict["blah"].Add();
  </code></pre>
  
  <p>Where am I going wrong?</p>
