PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// define a "query-by-example" principal - here, we search for all users
UserPrincipal qbeUser = new UserPrincipal(ctx);

// create your principal searcher passing in the QBE principal
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);

// find all matches
foreach (var found in srch.FindAll())
{
//Label1.Text = found.Name;
// do whatever here - "found" is of type "Principal" - it could be user, group, computer.....
DropDownList1.Items.Add(found.Name);
DropDownList2.Items.Add(found.UserPrincipalName);
}

Adding answer on behalf of OP.

PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// define a "query-by-example" principal - here, we search for all users
UserPrincipal qbeUser = new UserPrincipal(ctx);

// create your principal searcher passing in the QBE principal 
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);

// find all matches
foreach (var found in srch.FindAll())
{
    //Label1.Text = found.Name;
    // do whatever here - "found" is of type "Principal" - it could be user, group, computer..... 
    DropDownList1.Items.Add(found.Name);
    DropDownList2.Items.Add(found.UserPrincipalName);
}
