Copy a file with its original permissions

问题

When using the File.Copy() method the file is copied to its new directory however it loses its original permissions.

Is there a way to copy a file so that it doesn't lose the permissions?

I believe you can do something like this:

const string sourcePath = @"c:\test.txt";
const string destinationPath = @"c:\test2.txt"

File.Copy(sourcePath, destinationPath);

FileInfo sourceFileInfo = new FileInfo(sourcePath);
FileInfo destinationFileInfo = new FileInfo(destinationPath);

FileSecurity sourceFileSecurity = sourceFileInfo.GetAccessControl();
sourceFileSecurity.SetAccessRuleProtection(true, true);
destinationFileInfo.SetAccessControl(sourceFileSecurity);
