What does it throw? What kind of exception? Does it have a description? Have you debugged the code and found out which line causes the exception? Without answer to these questions, nobody will be able to answer you I'm afraid.

Solution 1

File.Copy require absolute path("C:\Users\Desktop\testFolder"). when the path given to File.Copy is relative(/testfolder), it will throw an exception "could not find a part of path".

In your case just make sure that the path given is absolute. This will fix your issue.

Debug your application and make sure the path is not relative.

I see a couple of issues...

1) File.OpenRead returns as System.IO.FileStream and now has a lock on that file until the stream is closed, you will receive an exception about the file is in use by another process. I do not see you reading the file so ommit that.

2) The System.IO.File.Copy needs to have a file name for both parameters, you cannot use a destination directory you must add the destination filename as well
e.g.

C#

System.IO.File.Copy(d.FullName, @"D:\Projects\EFO\Project_Synchronizer\Synchronizer WEB\otraWebService\otraWebService\Bilder\" + d.Name;);

C#

foreach (FileInfo d in directories)
                   {
                       if (d.Extension == ".jpg")//Bilder
                       {
                           CreateFolder("Bilder");
                                                     File.OpenRead(d.FullName); 
                           //you may want to check if file exists at destination already and implement action based on that (overwrite or rename with numeric copy value file(Copy 1).ext etc. just a suggestion to avoid exceptions in future                          
                           System.IO.File.Copy(d.FullName, @"D:\Projects\EFO\Project_Synchronizer\Synchronizer WEB\otraWebService\otraWebService\Bilder\" + d.Name);
                           
                       }
