Are you asking for a XCOPY method written in C# ?

need to write a recurisive function i.e a function that calls itself. Give
sometime, if you need a outline function I can give it..!

If you wanted to copy from a directory to another here is a code..

private bool CopyDirectory(string strSrceDir , string strDestDir )
{
try
{
DirectoryInfo SourceDir = new DirectoryInfo(strSrceDir);
DirectoryInfo DestDir = new DirectoryInfo(strDestDir);

if ( !DestDir.Exists )
DestDir.Create();

foreach( FileInfo ChildFile in SourceDir.GetFiles() )
{
ChildFile.CopyTo(Path.Combine(DestDir.FullName, ChildFile.Name), true);
}

foreach( DirectoryInfo SubDir in SourceDir.GetDirectories() )
{
if ( !SubDir.Exists )
SubDir.Create();
bool retVal;
retVal = CopyDirectory(SubDir.FullName,Path.Combine(DestDir.FullName,
SubDir.Name));
if (!retVal)
return false;
}

return true;

}
catch (Exception ex)
{
//log any error...
throw;
}
}

Thanks for the reply,

Arne, I don't know about XCopy funtion but am looking for some code which can do this.

VJ, If you could give me, that would be great.

thanks

Arne, I don't know about XCopy funtion but am looking for some code
which can do this.

It is a DOS/Windows command line command.

Code is something like:

private void XCopy(string dir1, string dir2)
{
string[] files = Directory.GetFiles(dir1);
foreach (string f in files) {
File.Copy(f, dir2 + f.Substring(dir1.Length), true);
}
string[] dirs = Directory.GetDirectories(dir1);
foreach (string d in dirs) {
XCopy(d, dir2 + d.Substring(dir1.Length));
}
}

I can not remember if it creates destination dirs that does
not exist. If not insert a Directory.Create call in the
method.

Thanks to all for the quick help.

I'm intrigued by your boolean return value. The method will only return
false if a "deeper" call to it returns false... so when will that
happen?

 

[VJ]

It will happen at any point a copy of a file or dir fails, and the copy will
stop at that point.

No, am I missing something, would like to learn.!

How? Where will it ever return false unless a nested call returns
false? If (as I believe) that's the only way it can return false, no
"leaf" call can ever return false, which means that no "higher" call
can return false either.

They can throw exceptions, of course, but that's not the same as
returning false.

If you want to give a counterexample, try to construct a series of
calls which will result in it returning false...

Beware that doing as you showed, won't preserve the security attributes (DACL's and SACL's)
of the input folders and files.
Many have been bitten by this!

Yes sure this one we thought of, and have leverage...
John good point, will try, thanks again for sharing the information.
Appreciate it.
