c# save overwrite image error -

im trying save file using im getting gdi+ error because im trying save on source file im using. solutions?

example:

private void form1_load(object sender, eventargs e) {    bitmap sourceimage = new bitmap("images/sourceimage.jpg");    sourceimage = cropbitmap(sourceimage, 0, 0, sourceimage.width, 50);    sourceimage.save("images/sourceimage.jpg", imageformat.jpeg); }  public bitmap cropbitmap(bitmap bitmap, int cropx, int cropy, int cropwidth, int cropheight) {     rectangle rect = new rectangle(cropx, cropy, cropwidth, cropheight);     bitmap cropped = bitmap.clone(rect, bitmap.pixelformat);     return cropped; } 

see the documentation constructor. section reads:

the file remains locked until bitmap disposed.

you must dispose sourceimage before saving new one. so, use different variables:

var sourceimage = new bitmap("images/sourceimage.jpg"); var croppedimage = cropbitmap(sourceimage, 0, 0, sourceimage.width, 50); sourceimage.dispose(); croppedimage.save("images/sourceimage.jpg", imageformat.jpeg); croppedimage.dispose();
