XCopy in .NET

[Brian Link]

Is there a Platform way to grab an entire directory and copy it? Or
will I have to iterate through the files and binary write them?

Thanks

If you prefer to use P/Invoke, it would be best that you change the title of
the post to "XCopy in P/Invoke".

To achieve XCopy in .Net, we may need to enumerate the contents of the
directory by using Directory.GetFiles() and Directory.GetDirectories(). Then
use FileCopy() to copy the files one by one.

Alternatively, we can use the following:

using System.Diagnostics;

ProcessStartInfo p = new ProcessStartInfo("xcopy");
p.Arguments = "/s c:\source c:\dest";
p.CreateNoWindow = true;
Process.Start(p);

I hope this helps.

Hello Brian,

Thanks for your post. As I understand, you want to copy a directory
directly without enumerating and copying each file and sub-folder. Please
correct me if there is any misunderstanding.

1. We are able to use the SHFileOperation() API to xcopy a directory.
Please refer to the following articles and sample:

SHFileOperation Function
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/pla
tform/shell/reference/functions/shfileoperation.asp

http://www.visualbasicforum.com/t125205.html

2. Since SHFileOperation() is unmanaged API, you may need to use P/Invoke
to call it from within your .NET app:

Consuming Unmanaged DLL Functions
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/htm
l/cpconconsumingunmanageddllfunctions.asp

3. I'd like to provide the following sample in case you will need to copy a
directory by iterating through the files in .NET:

Hope this helps.
