c# - 检查当前用户是否是活动目录组的成员

Question

我需要检查当前用户是否是活动目录组的成员。我开始获取当前用户，如下所示。现在我想知道如何检查这个 CurrentUser 是否在活动目录组“CustomGroup”中

string CurrentUser = WindowsIdentity.GetCurrent().Name;

Answer 1

您可以使用 .NET 3.5System.DirectoryServices.AccountManagement类。有关详细信息，请参阅 MSDN 文章管理 .NET Framework 3.5 中的目录安全主体。你可以使用类似的东西：

string CurrentUser = WindowsIdentity.GetCurrent().Name;

PrincipalContext context = new PrincipalContext(ContextType.Domain, "Domain");
UserPrincipal upUser = UserPrincipal.FindByIdentity(context, CurrentUser);
if(upUser != null)
{
    if (upUser.IsMemberOf(context, IdentityType.SamAccountName, "CustomGroup")) 
    {
        // The user belongs to the group
    }
}

在 .NET 3.5 或 4 中试试这个：

PrincipalContext infPC = new PrincipalContext(ContextType.Domain, "domain", "login", "password");
UserPrincipal infUP = new UserPrincipal(infPC);
PrincipalSearcher infPS = new PrincipalSearcher();
UserPrincipal foundUP;
GroupPrincipal infGP = new GroupPrincipal(infPC);
GroupPrincipal foundGP;
string CurrentUser = WindowsIdentity.GetCurrent().Name;

infUP.SamAccountName = CurrentUser;
infPS.QueryFilter = infUP;
foundUP = infPS.FindOne();
infGP.Name = "CustomGroup";
infPS.QueryFilter = infGP;
foundGP = infPS.FindOne();
bool ismember = foundUP.IsMemberOf(foundGP);
