Hi every body,

In my ASP.NET project,

I would like to save an image in stream instead of specific path and put this image from the stream into imageUrl property of an Image control.

Like the code:

C#

System.Drawing.Bitmap bitmap= new System.Drawing.Bitmap(ImagePath);        
bitmap.Save(MyStream, System.Drawing.Imaging.ImageFormat.Jpeg);        
MyIamgeControl.ImageUrl = MyStream;

No, it doesn't work like that. A stream is a temporary object existing only in the memory space of your application - it can't be assigned as a URL because it is a transitory object: it can be destroyed as soon as myStream goes out of scope - which could be at the end of the method, or could be when your page load has completed.

What are you trying to achieve that you think you need this?

You can not assign Stream object to ImageUrl property of Image control is simply bacuase it's Type is string.

However you can write your custom HttpHandler which will return Image Url for your dynamic stream.
