Question

基本上我尝试做的是将一台计算机/用户添加到一个组中。将对象添加到组后，我想查询对象的组以查看它们的内容。

似乎GetGroups方法的更新速度不够快。我的测试似乎总是失败。如果我在VS中放置一些断点，如果我等待足够的话，它会运行。

我刚接触到AccounManagement命名空间（我已经使用了pre .net 3.5代码）。我想我可以在代码中循环几次但是我看到其他人是否有这方面的建议。

我已完成以下单元测试

[Test]
public void Check()
{
    string distinguishedName = "ComputerDistinguishedName";
    string groupDN = "GroupDistinguished name";

    // Remove the identity from the group so it does crashes if it's already part of it.
    GroupCtrl.RemoveIdentityFromGroup(groupDN, distinguishedName);

    using (var ctx = new PrincipalContext(ContextType.Domain))
    {
        var group = GroupPrincipal.FindByIdentity(ctx, groupDN);

        Console.WriteLine(group.Members.Count);

        if (!group.Members.Contains(ctx, IdentityType.DistinguishedName, distinguishedName))
        {
            group.Members.Add(ctx, IdentityType.DistinguishedName, distinguishedName);
            group.Save();
        }

        foreach (var item in group.Members)
        {
            Console.WriteLine(item.DistinguishedName);
        }

        Console.WriteLine(group.Members.Count);
    }

    var isMemberOf = false;
    using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
    {
        var found = Principal.FindByIdentity(ctx, IdentityType.DistinguishedName, distinguishedName);

        if (found != null)
        {
            Console.WriteLine(found.DistinguishedName);
            foreach (var item in found.GetGroups())
            {
                Console.WriteLine(item.DistinguishedName);

                if (item.DistinguishedName == groupDN)
                {
                    isMemberOf = true;   
                }

            }
        }

        Assert.AreEqual(true, isMemberOf);
    }

    // Reset our group membership to run the test again.
    GroupCtrl.RemoveIdentityFromGroup(groupDN, distinguishedName);
}

修改1：

所以我尝试了两种不同的方法

1 -

我尝试获取getUnderlyingObject，然后循环遍历memberOf属性（结果相同）

2 -

我避免使用AccountManagement代码并使用DirectorySearcher并循环遍历memberOf属性，并且每次都会出现。 Sighh

Answer 1

所以我将代码更改为以下内容。使用DirectorySearch检查memberOf的旧方法每次都有效。我希望只使用AccountManagement类来完成这个项目。我想知道这个班级的未来版本是否会更好。

    [Test]
    public void Check()
    {
        //var test = new Constructor();
        var test = new AdContextObject();

        string distinguishedName = "ComputerDistinguishedName";
        string groupDN = "GroupDistinguished name";

        // Remove the identity from the group so it does crashes if it's already part of it.
        GroupCtrl.RemoveIdentityFromGroup(groupDN, distinguishedName);

        using (var ctx = test.GetContext())
        {
            var group = GroupPrincipal.FindByIdentity(ctx, groupDN);

            Console.WriteLine(group.Members.Count);

            if (!group.Members.Contains(ctx, IdentityType.DistinguishedName, distinguishedName))
            {
                Console.WriteLine("addGroup");
                group.Members.Add(ctx, IdentityType.DistinguishedName, distinguishedName);
                group.Save();
            }

            foreach (var item in group.Members)
            {
                Console.WriteLine(item.DistinguishedName);
            }

            Console.WriteLine(group.Members.Count);
        }

        DirectoryEntry de = new DirectoryEntry();
        de.Path = "LdapSource";

        DirectorySearcher ser = new DirectorySearcher(de);
        ser.Filter = "(&(ObjectCategory=computer)(name=ComputerName))";
        ser.PropertiesToLoad.Add("name");
        ser.PropertiesToLoad.Add("memberOf");

  var returnValue = ser.FindAll();
        var isMemberOf = false;

        foreach (SearchResult res in returnValue)
        {
            var memberOf = GetMultiValue(res, "MemberOf");

            foreach (var item in memberOf)
            {
                Console.WriteLine(item);
                if (item.Equals(groupDN, StringComparison.OrdinalIgnoreCase))
                {
                    isMemberOf = true;
                }
            }
        }

        Assert.AreEqual(true, isMemberOf);
        Console.WriteLine("old way worked fine");

        isMemberOf = false;
        using (PrincipalContext ctx = test.GetContext())
        {
            var found = Principal.FindByIdentity(ctx, IdentityType.DistinguishedName, distinguishedName);

            if (found != null)
            {
                foreach (var item in found.GetGroups())
                {
                    Console.WriteLine(item.DistinguishedName);

                    if (item.DistinguishedName.Equals(groupDN, StringComparison.OrdinalIgnoreCase))
                    {
                        isMemberOf = true;   
                    }

                }
            }

            Assert.AreEqual(true, isMemberOf);
        }

        // Reset our group membership to run the test again.
        GroupCtrl.RemoveIdentityFromGroup(groupDN, distinguishedName);
    }

    public static string[] GetMultiValue(SearchResult result, string fieldName)
    {
        string[] returnValue = null;

        if (result != null)
        {
            if (result.Properties.Contains(fieldName))
            {
                ResultPropertyValueCollection propertyValue = result.Properties[fieldName];
                if (propertyValue != null)
                {
                    if (propertyValue.Count > 1)
                    {
                        string[] valueArray = new string[propertyValue.Count];
                        for (int i = 0; i < propertyValue.Count; i++)
                        {
                            string valStr = propertyValue[i].ToString();
                            valueArray[i] = valStr;
                        }

                        returnValue = valueArray;
                    }
                    else if (propertyValue.Count == 1)
                    {
                        string[] tempString = new string[] { propertyValue[0].ToString() };
                        returnValue = tempString;
                    }
                    else
                    {
                        string[] tempString = new string[] { };
                        returnValue = tempString;
                    }
                }
            }
        }

        return returnValue;
    }

public class AdContextObject
{
    public PrincipalContext GetContext()
    {
        return new PrincipalContext(ContextType.Domain, "domainStuff", "MoreDomainStuff");
    }
}

system.DirectoryServices.AccountManagement中的GetGroups方法似乎确实刷新了
