I am writing a class (based on a class library) that creates a RAMDisk, and every X minutes I need to backup the contents of the RAMDisk to a physical location due to volatility. It was suggested to use CopyFileEx, as apparently the .NET file copy methods do not work.
For some reason I am getting an Invalid Arguements error when trying to use CopyFileEx though. I am assuming that I can still use the rest of the .NET methods in this function, but could just use some help fixing/cleaning it up a bit.
public static void CopyDirectoryVSS(string sourcePath, string targetPath)
{
// Check if the target directory exists, if not, create it.
if (Directory.Exists(targetPath) == false)
{
Directory.CreateDirectory(targetPath);
}
// Copy each file into it’s new directory.
foreach (string dir in Directory.GetDirectories(sourcePath))
{
foreach (string file in Directory.GetFiles(dir, "*.*"))
{
Console.WriteLine(@"Copying {0}\{1}", targetPath, file);
CopyFileEx(file, Path.Combine(target, file), null, 0, 0, 0);
}
}
// Copy each subdirectory using recursion.
DirectoryInfo sourceDir = new DirectoryInfo(@sourcePath);
DirectoryInfo TargetDir = new DirectoryInfo(targetPath);
foreach (DirectoryInfo diSourceSubDir in sourceDir.GetDirectories())
{
DirectoryInfo nextTargetSubDir = TargetDir.CreateSubdirectory(diSourceSubDir.Name);
CopyDirectory(diSourceSubDir, nextTargetSubDir);
}
}
