title: Create a folder only accesible by current logon user
body: <p>Using C#, how do I create a folder only accessible by the current windows user that is executing the program?</p>
  
  <p>That is, if I log in Windows as "MyDomain\John" and run the program to create a folder "D:\JohnOnly". After I log out and log back in as "MyDomain\Sam". The "D:\JohnOnly" can not be opened.</p>
  
  <p>Thanks, </p>
