c# – 如何查询所有组和组成员的Active Directory？

// create your domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// define a "query-by-example" principal - here,we search for a GroupPrincipal 
GroupPrincipal qbeGroup = new GroupPrincipal(ctx);

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

// find all matches
foreach(var found in srch.FindAll())
{
     GroupPrincipal foundGroup = found as GroupPrincipal;

     if(foundGroup != null)
     {
        // do whatever you need to do,e.g. put name into a list of strings or something
     }
}

如果你还没有 – 绝对阅读MSDN文章Managing Directory Security Principals in the .NET Framework 3.5,它很好地展示了如何充分利用System.DirectoryServices.AccountManagement中的新功能

当您拥有一个给定的组时,您可以使用以下方法轻松获取其所有组成员：

// find the group in question (or load it from e.g. your list)
GroupPrincipal group = GroupPrincipal.FindByIdentity(ctx,"YourGroupNameHere");

// if found....
if (group != null)
{
   // iterate over members
   foreach (Principal p in group.GetMembers())
   {
      Console.WriteLine("{0}: {1}",p.StructuralObjectClass,p.DisplayName);
      // do whatever you need to do to those members
   }
}
