What exactly do you need help with? Do you have any code that isn't working? You haven't provided enough info.

In which format are resumes, PDF or .doc(x) or something else?

If you want to show it embeded in web page, check this link: http://www.aspsnippets.com/Articles/Display-Word-document-on-web-page-in-ASP.Net.aspx

If you want to open it in Word on clients machine, then you should include in the response that you are sending Word content, so it would be something like this:

Response.AddHeader("content-disposition", "attachment; filename=Yourfile.doc);
Response.Charset = "";
Response.ContentType = "application/ms-word";
Response.WriteFile(Server.MapPath("file path"));
