c# Image from file close connection

c# filelock
RonaDona picture RonaDona · Nov 29, 2012 · Viewed 10.1k times · Source

I display an image using c# in a pictureBox. Then I want to change the image's name. I can't because I get that the image is being used by another process.

I open the image this way

 Image image1 = Image.FromFile("IMAGE LOCATION"); ;
        pictureBox1.Image = image1;

Then try to change it's name this way and I get an IO exception saying " The process cannot access the file because it's being used by another process.

System.IO.File.Copy(@"OldName", @"NewName"); //copy changes name if paths are in the same folder

Isn't the object image1 holding the image? Why is the file still locked by the previous process? Any suggestions would be appreciated. Many thanks!

Have a look at this question: Free file locked by new Bitmap(filePath)

To free the lock you need to make a copy of the bits:

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