DirectoryInfo doesn’t have a method for recursive copying of files and subfoders from one root to another. The following code ads the CopyTo method to the DirectoryInfo class using the new C# 3.0 feature named code extensions.
public static class Extensions
{
public static void CopyTo(this DirectoryInfo source, DirectoryInfo target)
{
if (!Directory.Exists(target.FullName))
{
Directory.CreateDirectory(target.FullName);
}
foreach (FileInfo fileInfo in source.GetFiles())
{
fileInfo.CopyTo(Path.Combine(target.ToString(), fileInfo.Name), true);
}
foreach (DirectoryInfo sourceSubDir in source.GetDirectories())
{
DirectoryInfo targetSubDir = target.CreateSubdirectory(sourceSubDir.Name);
sourceSubDir.CopyTo(targetSubDir);
}
}
}
Include this static class in your project and then you can use it like this:
DirectoryInfo info = new DirectoryInfo(@”C:\temp”);
info.CopyTo( new DirectoryInfo(@”C:\Copy of temp”));
