title: Create linq query as string
body: <p>I have a string that contains a linq query and i have a dynamic where clause also as string that contains many dynamic condition 
  here is my where clause</p>
  
  <pre><code>string strWhereString = "where a.id==1 &amp;&amp; a.name==\"something\"";
  </code></pre>
  
  <p>and here is my linq query string :</p>
  
  <pre><code>var query = "from a in context.tblName "+strWhereString;
  </code></pre>
  
  <p>the question is how to run this query and get result from the table?
  Is there any way to do that or Linq doesn't support this ?</p>
