I'm using c# to get a thumbnail of an image on upload and save it in a specific folder. I've given a path name to save it currently. I need to know how to save it without using a dialog box.

What I have tried:

if (image != null)
               {
                   imgThumb = image.GetThumbnailImage(100, 100, null, new IntPtr());
                   this.Refresh();

                   imgThumb.Save("C:\\Users\\Acer\\Pictures\\Camera Roll\\thumbnail2.jpg");
                   MessageBox.Show("Image Saved Successfully");

               }

Without dialog box means? are you passing folder path in the dialog box or you don't need dialog box for upload?

To upload the image I've used an open dialog box but for save i need to know if there's any way to save the image without using the save dialog box and it could be save images in the same folder with different names.

Alright, and what is the problem with your code?

Member 13958707 27-Aug-18 2:19am

Since i've defined a path, the image could be saved only once by the defined name in the path.

imgThumb.Save("C:\\Users\\Acer\\Pictures\\Camera Roll\\thumbnail2.jpg");

Ok, but once the image is saved and you have to save the new image you again have to enter the new path or basically image name as the path is same. Right?

Image path is same but the name has to be different when saving it.

You need to use a variable to create a different filename each time you save.

Solution 1

imgThumb.Save("C:\\Users\\Acer\\Pictures\\Camera Roll\\thumbnail2.jpg");

Maybe you need to change your Thumbnail2.jpg.
you are all time saving on the same file.

string strPictures = "Thumbnail" + 1;
imgThumb.Save(string.Format(@"C:\Users\Acer\Pictures\Camera Roll\{0}", strPictures));

Solution 2

string strPictures = "Thumbnail" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".jpg";
imgThumb.Save(string.Format(@"C:\Users\Acer\Pictures\Camera Roll\{0}", strPictures));

This way you will have always new image name
