You can use the System.DirectoryServices.AccountManagement namespace to access Active Directory data.
The MSDN documentation for it (.Net 3.5) is here: http://msdn.microsoft.com/en-us/library/system.directoryservices.accountmanagement.groupprincipal(v=vs.90).aspx
For Example:
var domainName = "yourdomain.com";
var groupName = _query.Text;
var queryUser = "fred";
var queryUserPassword = "secretstuff";
var principalContext = new PrincipalContext(ContextType.Domain, domainName);
GroupPrincipal groupPrincipal = GroupPrincipal.FindByIdentity(principalContext, groupName, queryUser, queryUserPassword);
var members = groupPrincipal.GetMembers(true); //true to recursively get members
Example Two (in a test webpart):
public class QueryActiveDirectory : WebPart
{
private Label _results;
private TextBox _query;
private Button _submit;
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
_results = new Label();
_query = new TextBox();
_submit = new Button();
_submit.Text = "Submit";
_submit.Click += SubmitOnClick;
}
private void SubmitOnClick(object sender, EventArgs eventArgs)
{
try
{
var domainName = "yourdomain.com";
var groupName = _query.Text;
var queryUser = "fred";
var queryUserPassword = "secretstuff";
var principalContext = new PrincipalContext(ContextType.Domain, domainName);
GroupPrincipal groupPrincipal = GroupPrincipal.FindByIdentity(principalContext, groupName, queryUser, queryUserPassword);
if (groupPrincipal == null)
{
_results.Text = "The group was not found.";
return;
}
var members = groupPrincipal.GetMembers(true);
var membersList = new ArrayList();
foreach (Principal member in members)
{
membersList.Add(member.DisplayName);
}
var output = new StringBuilder();
output.AppendLine(String.Format("<span>Members of the {0} group:</span><br/>", groupName));
foreach (string s in membersList)
{
output.AppendLine(String.Format("<span>{0}</span><br/>", s));
}
_results.Text = output.ToString();
}
catch (Exception ex)
{
_results.Text = String.Format("Error getting group from Active Directory. Error: {0}", ex.Message);
}
}
protected override void CreateChildControls()
{
Controls.Add(_query);
Controls.Add(_submit);
Controls.Add(new LiteralControl("<br/>"));
Controls.Add(_results);
}
}

I just added a webpart to the TechNet Gallery that allows administrative users to upload, crop and format user profile photos. Check it out here:
