我试图实现这里描述的IsActive方法是帐户活动,但我得到一个对象引用不设置为对象的实例。

       private bool IsActive(DirectoryEntry de)
    {
        DirectoryEntry myEntry = GetDirectoryEntry();
        if (myEntry.NativeGuid == null) return false;
        int flags = (int)myEntry.Properties["userAccountControl"].Value;
        if (!Convert.ToBoolean(flags & 0x0002)) return true; else return false;
        return false;
    }
   private void SubmitData()
    {
        System.Guid guid = Guid.NewGuid();
        logInfo.IPaddress = IPAddress;
        if (!String.IsNullOrEmpty(txtUser.Text))
        {
            string username = txtUser.Text.ToString();
            if (IsActive(de) != false)
            {
                if (DateTime.Now.Subtract(passwordLastSet).TotalHours > 1)
                {
                    lblPasswordLastSet.Text = passwordLastSet.ToString();
                    lblStatus.Text = "all is good";
                }
                else
                {
                    lblStatus.Text = "oops, you reset your password less than 24 hours ago!";
                    lblPasswordLastSet.Text = passwordLastSet.ToString();
                }
            }
            else
            {
                lblStatus.Text = "your account is not active";
            }
        }
    }

如果你使用的是。net 3.5及以上版本,你应该检查一下System.DirectoryServices.AccountManagement (S.DS.AM)命名空间。阅读这里的所有内容:

管理。net Framework 3.5中的目录安全主体

基本上,您可以定义域上下文并轻松地在AD中查找用户和/或组:

// set up domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
// find user by name
UserPrincipal user = UserPrincipal.FindByIdentity("John Doe");
if(user != null)
{
   // check if account is locked out
   if(user.IsAccountLockedOut)
   {
      // do something if locked out....
   }
}

新的S.DS.AM使在AD中处理用户和组变得非常容易:
