body: <p>The type or namespace name 'c' could not be found (are you missing a using directive or an assembly reference?)</p>
  
  <p>I do have this namespace added "using System.Web.UI.WebControls;" why this error ??   </p>
  
  <pre><code> protected void DoSomething(Control control)(
      {
  
          foreach (Control c in control.Controls)
          { 
              if(typeof(c).Equals(Telerik.Web.UI.RadEditor))
              {
                 Telerik.Web.UI.RadEditor rad = c as Telerik.Web.UI.RadEditor;
                 rad.CssClass = "MyStyle";
                    label1.Visible = true; label1.Text = "dhchk";
                 // control.CssFiles.Add("~/styles/myStyle.css"); 
              }
              else

                    DoSomething(c);
