I want to make a page when the user enter that page he see an image
Professor_Dim prof = sdc.Professor_Dims.SingleOrDefault(x => x.P_ID == 0);
if (FileUpload1.HasFile && FileUpload1.PostedFile.ContentLength > 0) {
string fileName = FileUpload1.FileName;
byte[] fileByte = FileUpload1.FileBytes;
Binary binaryObj = new Binary(fileByte);
prof.P_Image = binaryObj;
sdc.SubmitChanges();
}
this code upload the image to database i want to retrieve that image in another page
ASP.net MVC
I did it a little bit different. I stored the byteData as is in the database and then did the following:
Bitmap bmp;
byte[] img = //retrieve bytes from DB
if (img == null)
return new EmptyResult();
using (MemoryStream ms = new MemoryStream(img))
{
bmp = new Bitmap(Image.FromStream(ms));
}
If you're using ASP MVC you can return an ImageResult where you place the bmp as the Image and use for example for the ImageFormat ImageFormat.Jpeg.
ASP.NET
byte[] bytes = //retrieve the Image bytes from the database;
string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);
Image1.ImageUrl = "data:image/jpeg;base64," + base64String;
