Hello

I want to save a image to specified path as a jpg format.
But I'm getting some error messages.

Codes are shown below ;

path ="C:\\image.jpg ";
FileStream fs = new FileStream(path ,FileMode.Creat e,FileAccess.Wr ite);
MemoryStream ms = new MemoryStream();
i.Save(ms,Image Format.Jpeg);
byte[] b = new byte[ms.Length];
ms.Write(b,0,b. Length);
fs.Write(b,0,b. Length);
fs.Close();

i is image object,it was loaded from anywhere(from path or database),
We suppose that size of i object is 223 kb and after codes mentioned above a
image is saved and it's size is 223kb but,picture in the saved file is not
appear.

i object is load with codes below;

String path;
Stream myStream;
OpenFileDialog openFileDialogP icture = new OpenFileDialog( );
openFileDialogP icture.InitialD irectory = "C:\\temp\\imag e.jpg";
openFileDialogP icture.Filter = "picture files (*.jpg)|*.jpg";
openFileDialogP icture.FilterIn dex = 2 ;
openFileDialogP icture.RestoreD irectory = true ;
if(openFileDial ogPicture.ShowD ialog() == DialogResult.OK )
{
if((myStream = openFileDialogP icture.OpenFile ())!= null)
{
path = openFileDialogP icture.FileName ;
Image i = Image.FromFile( path);
}
}

finally,How can I save this image object to specified path.

Thanks.

Hi Brenny,

If you just want to copy this file to another location I would recommend using File.Copy instead of saving it again since that would just create a slightly lower quality JPG than you had to begin with.

In any case, to save an Image as JPG just use
Image.Save(path , ImageFormat.Jpe g);

Btw, when you say you get error message it helps if you tell us the exact errors (copy/paste).
