c# - MVC4 - Ajax.ActionLink() GET returning 500 internal server error -

When I click on a Ajax.ActionLink , I get 500 internal server errors . I have a profile page which is composed of several partial forms. Each partial has asked the server to allow Ajax to edit the user information related to that particular partial.

I said that 3 partially implemented with functionality, which works fine. On which I am working, it should initially show a list of uploaded images - if the user did not upload any image, Ajax.ActionLink will be displayed first, which will be clicked on Provides a user to partially upload images.

When I press the link, then I'm looking into Chrome:

here gET and POST ActionResults :

  // / / receive / tenants / TenantUploadReference [HttpGet] public ActionResult TenantUploadReference () {try {var currentTenant = tenantRepository.GetLoggedInTenant (); If (currentantant.refesphoto == empty) {currentTenant.ReferencePhotos = currentTenant.ReferencePhotos ?? New list & lt; Reference photo & gt; (); } Return a partial view ("_ tenantUploadReferencePartial", currentTenet.rereferols.toList ()); } Hold (exception e) {ModelState.AddModelError ("", e); See Return (); }} // // POST: / tenants / TenantUploadReference [HttpPost] public ActionResult TenantUploadReference (HttpPostedFileBase file, tenant) {if {try {if (file.ContentLength & gt; 10240) {ModelState.AddModelError ((file = null! ) "File", "the file size should not exceed 10 KB"); See Return (); } Var supportedTypes = new [] {"jpg", "jpeg", "png", "jpg", "jpeg", "png"}; Var fileExt = System.IO.Path.GetExtension (file.FileName) .Substring (1); If (Supported text. Canton (File AEXT)) {ModelState. Adod Eltar ("Photo", "Invalid type. Only the following types are supported (JPG, JPEG, PNG)."); See Return (); } (Var db = new LetLordContext ()) using {var reference = db.Image.Create & lt; Reference photo & gt; (); // Convert HttpPostedFileBase byte array to memoryStream target = new MemoryStream (); File.InputStream.CopyTo (target); Byte [] Photo = Target. ToArray (); Reference. File = photo; Reference. Format = fileext; Reference. Data-uploaded = date time.NEW.DAT; Reference. Description = ""; Context.Name = ""; Db.Image.Add (reference); Db.SaveChanges (); Back partial view ("_ tenantReference PhotoShot", file); }} And {return view (); }} Hold (exception e) {ModelState.AddModelError ("", e); See Return (); }}   
 I  to step through the debugger with a break point ActionResult  hit  return PartialView  and no exceptions Is thrown away.    _TenantUploadReferencePartial  I  
  @using (Ajax.BeginForm ( "TenantUploadReference", "tenants", FormMethod.Post, using new AjaxOptions {InsertionMode = InsertionMode.Replace, HttpMethod = "post", UpdateTargetId = "tenant reference pictures"}))   
 and  _TenantReferencePhotosPartial  (where  ActionLink I throw a 500 error) I use this  
  @if (Model.ReferencePhotos == faucet) {& lt; H3 & gt; You have not uploaded any references! Upload @ Ajaks.akshnlink ( "Now?", "Tennant Uploderefrens" new Ajax option {Apdettabagaidi = "tenant-reference photos," Prvishtimod = Nivishtimod. Replays, Acteepimaideepi = "GET", Lodingilementaid = "Ajax-loader" }) And lieutenant; / H3 & gt; It may also be useful to know that other part-time work on the page does the required work, so I do not think it is an issue with missing scripts. I am at a loss as to why this is happening - a solution would be greatly appreciated.   
 
 
 I 'has solved the problem I was returning the  currentTennet. Reference photo ..ToList ()  which threw a  Argumental exposure . Now I'm just returning to  current center , and GET is working as expected.
