How to dispose a stream after using it in Image?

I have the stream of the Image and I convert it into image by the below code

Image imagefromstream = Image.FromStream(stream);

When I draw this image in graphics, it draws the image.

But, if I dispose the stream after drawing in graphics, the image is not drawn.

Can anyone help me to dispose the image stream

In this case, you have the direct reference of memory stream and if you dispose it, image also will get disposed.

So you get the source from the stream and have it in a BitmapImage, set that BitmapImage as the source for the Image..

var imageSource = new BitmapImage();
imageSource.BeginInit();
imageSource.StreamSource = memoryStream;
imageSource.CacheOption= CacheOption.OnLoad;
imageSource.EndInit();

// Assign the Source property of your image
image.Source = imageSource;

According to MSDN here:

You must keep the stream open for the lifetime of the Image.

You'll have to Dispose the stream when you close your application (or whenever you no longer need the Image)
