html - Redirection to an action with razor by clicking into button -

I have an asp.net mvc4 application. In which I have to insert an image with an URL for any action:

   & Lt; / A & gt;   
 But an invalid url error appears. So what is the reason for this error? How can I fix my code?   
 
 
 You can use in these ways 
  Method 1:   >  @html.exelink ("retor", "retror", "client", blank, new {@ class = "background"})   
 CSS:  
  a.background {background: url (../ images / image.gif) No-repeat top left; Display area; Width: 150px; Height: 150px; Text indent: -9999 pixels; / * Link text * /}   
  Method 2:   
  & lt; A href = '@ url.Action hides ("MyAction", "Mac Controller") & gt; & Lt; Img src = '@ Url.Content ("~ / content / images / image.gif")' / & gt; & Lt; / A & gt;   
  Method 3:   
  @ HTMLActionLink ("Retor", "Retror", "Client", New { Style = "background: url ('../../content/images/image.gif') Any repeat center correct; Display: block; height: 24px; width: 24px;"})  < / Ex>
