Hello
I have an

element in my .html file. When user select his/her image, I get the selected image using JavaScript and send it to controller as JSON:

var _Data = { Image = $("#ImageFileUpload").val();

and in my controller, I save it in my Data Base:

byte[] binData;
byte[] byteArrey = System.Text.Encoding.UTF8.GetBytes(_LawyerArgument.Picture);
MemoryStream _Stream = new MemoryStream(byteArrey);
UserPicture _UserPicture = _LawEntities.UserPicture
     .Where(c => c.UserId == _UserID).SingleOrDefault();
if (_UserPicture != null)
{
   using (var _BinaryReader = new BinaryReader(_Stream))
   {
       binData = _BinaryReader.ReadBytes(Int32.Parse(_Stream.Length.ToString()));
       _BinaryReader.Close();
   }
    _UserPicture.picture = binData;
}
else
{
    _UserPicture = new UserPicture();
    using (var _BinaryReader = new BinaryReader(_Stream))
    {
        binData = _BinaryReader.ReadBytes(Int32.Parse(_Stream.Length.ToString()));
         _BinaryReader.Close();
    }
     _UserPicture.picture = binData;
     _LawEntities.UserPicture.Add(_UserPicture);

}
_LawEntities.SaveChanges();

it stores record in my table and I can see binary data as image, but I think I am wrong in Insert OR Fetch data. because when I want to show selected image to user in web site, it does not show the image. I have no error in debug or run-time.

I retrieve image by these codes:

var _LawyerPictures = _Law.UserPicture
.Take(4)
.Select(s => new
{
    Picture = s.picture,
    ID = s.UserId

}).ToList();

foreach (var item in _LawyerPictures)
{
    string _Path = Path.Combine(Directory.GetCurrentDirectory(),               @"/TemporaryUserPictures/");
    if (!Directory.Exists(_Path))
    {
        Directory.CreateDirectory(_Path);
        var path = HttpContext.Current.Server.MapPath(_Path + item.ID + ".png");
        File.WriteAllBytes(path, item.Picture);
     }
}

I save images to a temporary folder and then use it to show them.

What I have tried:

I have tried codes above, but I do not know where I have the problem, In storing image, or in retrieve.

thanks in Advance
