我有这些课程：

public class ZoneMember
    // a zone member is a member of a zone
    // zonemembers have ports, WWPNs, aliases or all 3
{
    private string _Alias = string.Empty;
    public string MemberAlias {get{return _Alias;} set{_Alias = value; } }
    private FCPort _Port = null;
    public FCPort MemberPort { get { return _Port; } set { _Port = value; } }
    private string _WWPN = string.Empty;
    public string MemberWWPN { get { return _WWPN; } set { _WWPN = value; } }
    private bool _IsLoggedIn;
    public bool IsLoggedIn { get { return _IsLoggedIn; } set { _IsLoggedIn = value; } }
    private string _FCID;
    public string FCID {get{return _FCID;} set{ _FCID=value; } }
}

public class Zone
{ 
    public List<ZoneMember> MembersList = new List<ZoneMember>();
    private string _ZoneName;
    public string zoneName{ get{return _ZoneName;}  set{_ZoneName=value;} }

    public Zone(string n) { zoneName=n; }

}

public class ZoneSet 
{    
    private string _ZoneSetName;
    private int _VSANNum;
    public string ZoneSetName{get{ return _ZoneSetName;}  set{_ZoneSetName=value;} }
    public int VSANNum{ get{ return _VSANNum;}  set{_VSANNum=value;} }
    public bool isActive;
    public List<Zone> ZoneList = new List<Zone>();
}

我想在 Zoneset 中找到所有具有区域成员的区域，该成员具有特定值的成员列表中的属性。

我知道这样的事情会起作用 - 在这种情况下，我正在搜索 WWPN 属性：

// assumes myZoneSet has already been instantiated ad has zones in it
// and inputWWPN in the select statement has the value we want

List<Zone> myZoneList = new List<Zone>();

foreach (Zone z in myZoneset)
{   
var zm=null;

        zm = from member in z.MembersList where member.MemberWWPN == inputWWPN select member;  
  // if we find a matching member, add this zone to the list 
  if (zm != null)
   {  myZoneList.Add(z);
    }
}

有没有办法使用 LINQ 来完成整个事情？我不确定数据库术语中的术语是什么。

这个小查询应该是您所需要的：

var myZoneList = myZoneSet.ZoneList
    .Where(z => z.Any(member => member.MemberWWPN == inputWWPN))
    .ToList();

尝试这个 - 

List<Zone> listOfZone = zoneSet.ZoneList.Where(e => e.Any(p => p.MemberWWPN == inputWWPN)).ToList();

 myZoneList =myZoneSet.SelectMany(z => z.MembersList).Where(m => m.MemberWWPN == "somestring").ToList();

我希望这将有所帮助。
