Question

在构建过滤器以查找具有特定值的对象时，Principal Searcher似乎做得很好。没有呢？例如，如何构建过滤器以排除名称中包含“Joe”的所有人。下面的代码不起作用。

        PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
        UserPrincipal qbeUser = new UserPrincipal(ctx);
        PrincipalSearcher srch = new PrincipalSearcher(qbeUser);

         //this is the problem line.  How to format to exclude values with Joe?
         qbeUser.Name != "*Joe*"; 

        srch.QueryFilter = qbeUser;
        foreach (var found in srch.FindAll())
         { do something to non Joe users... }

似乎无法使用PrincipalSearcher。

两种可能的解决方法：

使用PrincipalSearcher获取所有用户并在客户端进行过滤

PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
UserPrincipal qbeUser = new UserPrincipal(ctx);
PrincipalSearcher srch = new PrincipalSearcher(qbeUser);

srch.QueryFilter = qbeUser;
foreach (var found in srch.FindAll())
{ //filter out users with "Joe" in its name }

使用DirectorySearcher

DirectoryEntry de = new DirectoryEntry("LDAP://domain.com/dc=domain,dc=com", "user", "pwd");
DirectorySearcher srch = new DirectorySearcher(de);

srch.Filter = "(&(objectCategory=person)(objectClass=user)(!(name=*Joe*)))";
srch.SearchScope = SearchScope.Subtree;
// add the attributes
srch.PropertiesToLoad.Add("distinguishedName");
using (SearchResultCollection results = srch.FindAll())
{
    foreach (SearchResult result in results)
    {
        string dn = result.Properties["distinguishedName"][0] as string;
        Console.WriteLine("- {0}", dn);
    }
}

AD PrincipalSearcher：搜索属性不包含某些值的位置
