Dear All,
Actually i am getting this error while trying to delete file.
the process cannot access the file because it is being used by another process

here is my code:

C#

public static byte[] GetTransparentArrayFromFileWithDelete(string pathToFile)
        {
            byte[] newImage = new byte[0];
            using (Bitmap bmp = new Bitmap(pathToFile))
            {
                Color pixel = bmp.GetPixel(0, 0);
                Graphics graphics = Graphics.FromImage(bmp);
                Color backColor = bmp.GetPixel(1, 1);
                bmp.MakeTransparent(backColor);
                ImageConverter converter = new ImageConverter();
                newImage = (byte[])converter.ConvertTo(bmp, typeof(byte[]));
            }
            try
            {
                File.Delete(pathToFile);

Solution 2

See Bitmap Constructor (String) (System.Drawing)[^]:

Quote:
The file remains locked until the Bitmap is disposed.

So call Dispose() before deleting the file or delete the file after the Bitmap instance has been finalized.

Actually i called bmp.Dispose(); but the same issue occures.
Notice: I am using File.Delete outside bitmap scope.
Any Ideas??

Did you have opened the same file somewhere else in your application or even another application?

You can use the Process Explorer (https://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) to check which process has opened the file (just enter the file name when selecting the 'Find' menu item).

Actully i tried again after removing this line of code:
Graphics graphics = Graphics.FromImage(bmp);
And it works fine now..
Thanks alot..

Thank you for your feedback that the problem is solved.

That takes a reference to the bitmap and was therefore probably the reason.
