Answer 1

Its hard to say without seeing what results you are getting, but it looks like maybe you are over qualifying the path with slashes.

Try this

string pathMaterData = Path.Combine(ServerName, "MaterData")

if (!Directory.Exists(pathMaterData))
{
  Directory.CreateDirectory(pathMaterData);
}
