Active Directory用户条目和组条目

Question

I'm currently having an issues to where I cannot get my Organizational Unit to be recognized as an argument with creating a new Active Directory user, and assigning them to a OU. It gives me the error, "GetPrincipalContext" takes 1 argument, and I'm lost as what went wrong. If further information if needed, please let me know.

    #region Variables
    private string sdomain = "test";
    private string sdefaultou = "OU=Dackup Users, OU=Dackup, DC=Test, Dc=com";
    private string sdefaultrootOU = "DC=test, DC=com";
    private string sServiceUser = @"ServiceUser";
    private string sServicePassword = "ServicePassword";

Use the below code

PrincipalContext ouContex = new PrincipalContext(ContextType.Domain, "TestDomain.local",           "OU=TestOU,DC=TestDomain,DC=local");

        for (int i = 0; i < 3; i++)
        {
            try
            {
                UserPrincipal up = new UserPrincipal(ouContex);
                up.SamAccountName = "TestUser" + i;
                up.SetPassword("password");
                up.Enabled = true;
                up.ExpirePasswordNow();
                up.Save();
            }
            catch (Exception ex)
            {

            }
        }
