                   image1.InputStream.Read(user.UserImage, 0, image1.ContentLength);

Now I want to Store this into session and Retrieve on Dashboard Page.

But image is not showing. pls help.

What I have tried:

In Controller:

HTML

string imageDataURL = string.Format("data:image/png;base64,{0}", dataitem.UserImage);
               Session["UserImage"] =  imageDataURL;

In View:

HTML

var img =  (Session["UserImage"]);
                                  
  string imageSrc = string.Format("data:image/gif;base64,{0}", img);
  <img src="@imageSrc" width = "60" height = "60" class="img-profile rounded-circle"/>

The data you store in the Session already has the data:image/gif prefix, however you add it again in your view, so just miss that step out

@{
    var img = (Session["UserImage"]);
}
<img src="@img" width="60" height="60" class="img-profile rounded-circle" />

Also you don't seem to be converting the byte array to base64, if dataitem.UserImage is a byte array then use

string imageDataURL = string.Format("data:image/png;base64,{0}", System.Convert.ToBase64String(dataitem.UserImage));
