 file.SaveAs(locatio开发者_如何学编程n);

 Image image = Image.FromFile(location,false);

 image.Save(location, System.Drawing.Imaging.ImageFormat.Png);

image.fromFile line [3] caused Exception that out of Memory. can someone show me how i can do this in c#.

The file come from PNG using Ajax Request are come as octet type as Mime type so how i can do that.

Assuming you want to convert the image to PNG (otherwise there's no need to save the image once, reload it and re-save it again), it might be a good idea to avoid loading the image twice. See if something like this helps:

Image.FromStream(file.InputStream, false).Save(location, System.Drawing.Imaging.ImageFormat.Png);

file.SaveAs(location);

already saved the image at the given location or threw an exception, so the following lines are unnecessary.

        Bitmap bmp = new Bitmap(file.InputStream);
        bmp.Save(filename, ImageFormat.Png);
