Open Image from file, then release lock?

Question

I'm using the following line of code to open an

Image

from a file:

pictureBox1.Image = Image.FromFile("test.png");

I expect it to lock the file, load the image to memory, set

pictureBox1.Image

to the copy in memory, and release the lock. In reality, the lock won't go away until I

Dispose()

of the

Image

in memory. I can not release the lock on the file on the harddrive that I am no longer using until I get rid of the file in memory that I am using.

Microsoft's site mentions it in a C#-labeled article, but their solution is written in visual basic, which is useless to me.

In summary:
I want to set

pictureBox1.Image

to the image stored in

"test.png"

, then let the user edit or delete

"test.png"

or whatever.

Answer 1

The approach with stream is not correct.

See here https://stackoverflow.com/a/8701748/355264

Correct code from above link:

Image img;
using (var bmpTemp = new Bitmap("image_file_path"))
{
    img = new Bitmap(bmpTemp);
}
