title: Object reference required for non-static field, method, or property
body: <p>I want to use the Caching.Cache(...) method, like so:</p>
  
  <pre><code>Cache.Insert("Interview Questions", datatable, sqlcachedep)
  </code></pre>
  
  <p>or</p>
  
  <pre><code>System.Web.Caching.Cache.Insert("Reading List", datatable, sqlcachedep);
  </code></pre>
  
  <p>There is no problem with the variables, but I get this error message in either case:</p>
  
  <blockquote>
    <p>Error 1 - An object reference is required for the non-static field, method, or property 'System.Web.Caching.Cache.Insert(string, object, System.Web.Caching.CacheDependency)' </p>
  </blockquote>
  
  <p>How can I fix this?</p>
  
  <p>Thanks</p>
