你检查的权限？

I have a function which first reads an image from disk, resizes it and then saves to another directory.

when i use the Bitmap.Save(directory + theimagename) it returns the error as i stated in the question title.

i checked the directory is right, and the given image name doesn't exist in that dir.

what is weird, is that the same code works great on the local machine. but when i upload it to my shared hosting space, it just doesn't work.

the code is below.

bmpOut = new Bitmap(Size, Size);
Graphics g = Graphics.FromImage(bmpOut);
g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
g.FillRectangle(Brushes.White, 0, 0, Size, Size);
int topBottomPadding = 0; int leftRightPadding = 0;
if (Size > lnNewWidth + 1)
    leftRightPadding = Convert.ToInt32((Size - lnNewWidth) / 2);
else if (Size > lnNewHeight + 1)
    topBottomPadding = Convert.ToInt32((Size - lnNewHeight) / 2);
g.DrawImage(loBMP, leftRightPadding, topBottomPadding, lnNewWidth, lnNewHeight);
Bitmap bmp = new Bitmap(bmpOut);
if (bmp != null)
    bmp.Save(ResizedOutput); // C:\Inetpub\vhosts\DomainName\httpdocs\ProductImages\500px\gigabyte_ga_ep45_ds4_profilelarge[1].jpg
bmp.Dispose();
bmpOut.Dispose();
g.Dispose();
loBMP.Dispose();

stack trace:

From ASP Net - GDI+ and SAVE JPG or BMP on the server

99.9% of the time, when using GDI, 'a generic error occured' means that the directory you are trying to save to doesn't ahve the proper permissions. Typically, you need to make sure that directory is allowing asp.net to modify files.

Did you check the permissions?
