MVC引用asp.net报表（测试小例子）

  public class Default1Controller : Controller
     {
         //
         // GET: /Default1/

         public ActionResult Index()
         {
             return View();
         }

         public JsonResult ReportFileName()
         {
             DirectoryInfo d = new DirectoryInfo(Server.MapPath("~/") + "Report/");
             FileSystemInfo[] fsinfos = d.GetFileSystemInfos();
             List<string> fileName = fsinfos.Where(p => p.Name.IndexOf(".rdlc", StringComparison.Ordinal) == -).Select(fsinfo => fsinfo.Name.Replace(".rdl", "")).ToList();
             return Json(new { Result = fileName });
         }

         public JsonResult ExistsFile(string keyId)
         {
             string path = Server.MapPath("~/") + "Report/" + keyId + ".rdl";
             return this.Json(new { ResultBool = System.IO.File.Exists(path) });
         }
     }
