System.drawing. image

Hi,

I have this question.
When I use the FileUpload WebControl to post an Image (= SourceFile) that I
want to resize and write to the server, I keep getting this situation.
If that SourceFile is located in My Documents (as in "C:\Documen ts and
Settings\29\Mij n documenten\SubF olderFolder\Img Name.jpg"), I keep getting a
'FileNotFoundEx ception'. That doesn't happen when I get the SourceFile from
"C:\Folder\imgN ame".

What can I do about this ?

Actually I found a workaround, but this gives me an error as well....

I can save the PostedFile like this
PostedFile.Save As(imgPath + "DummyName" );

After which I can do these steps without any problem

System.Drawing. Image srcImage =
System.Drawing. Image.FromFile( imgPath + DummyName);

Graphics graphicOrig = Graphics.FromIm age(srcImage);
graphicOrig.Com positingQuality = CompositingQual ity.HighQuality ;
graphicOrig.Smo othingMode = SmoothingMode.A ntiAlias;
graphicOrig.Int erpolationMode =
InterpolationMo de.HighQualityB icubic;

Rectangle rectOrig = new Rectangle();
graphicOrig.Dra wImage(srcImage , rectOrig);
srcImage.Save(N ewFileName, ImageFormat.Jpe g);

srcImage.Dispos e();

The final srcImage is perfect, and everything I need but when I want to do
this
File.Delete(img Path + dummyName);

I get the IOException that File cannot be deleted:
"The process cannot access the file 'ImgPAth\dummyN ame' because it is being
used by another process."

Does anyone know what I can do about these issues?

Try also

graphicOrig.Dis pose();

Try getting the actual path of your posted file from System.IO.Path
namespace. You can use it like this:

string FileName =
System.IO.Path. GetFileName(fil eUpload.PostedF ile.FileName); // fileUpload is
the id of fileupload html control

Sorry forgot to mention. You cannot manipulate an image at client side,
therefore you need to save the image at server in order to resize it. And
for the delete problem, dispose the Graphics and Rectange object that you
have created before deleting the image.

graphicOrig.Dis pose();
rectOrig.Dispos e();
