Okay, I'm hoping I am just somehow overlooking the obvious. I have the following code situation below. For some reason, the SequenceNo property is still getting mapped even though I'm calling Ignore(). I'm using the latest. I also had tested it with two different classes in the same project and it seemed to work, so what's wrong with this scenario then?
This is the domain object:
public class CableID
{
private string _panelID1;
public string PanelID1
{
get { return _panelID1; }
private set { _panelID1 = value; }
}
private string _panelID2;
public string PanelID2
{
get { return _panelID2; }
private set { _panelID2 = value; }
}
private int _sequenceNo;
public int SequenceNo
{
get { return _sequenceNo; }
private set { _sequenceNo = value; }
}
private DateTime _inService;
public DateTime InService
{
get { return _inService; }
set { _inService = value; }
}
private string _id;
public string ID
{
get { return _id; }
private set { _id = value; }
}
public CableID(string panelID1, string panelID2, int sequenceNo)
{
this.PanelID1 = panelID1;
this.PanelID2 = panelID2;
this.SequenceNo = sequenceNo;
this.ID = string.Format("({0}-{1}){2}", this.PanelID1, this.PanelID2, this.SequenceNo);
}
public CableID(string id)
{
if (string.IsNullOrEmpty(id))
throw new ArgumentNullException("id");
this.ID = id;
}
}
And here is the DTO Object:
public class CableIDDTO
{
private string _panelID1;
public string PanelID1
{
get { return _panelID1; }
set { _panelID1 = value; }
}
private string _panelID2;
public string PanelID2
{
get { return _panelID2; }
set { _panelID2 = value; }
}
private int _sequenceNo;
public int SequenceNo
{
get { return _sequenceNo; }
set { _sequenceNo = value; }
}
private string _id;
public string ID
{
get { return _id; }
set { _id = value; }
}
public CableIDDTO()
{ }
public CableIDDTO(string panelID1, string panelID2, int sequenceNo)
{
this.PanelID2 = panelID1;
this.PanelID1 = panelID2;
this.SequenceNo = sequenceNo;
this.ID = string.Format("({0}-{1}){2}", this.PanelID2, this.PanelID1, this.SequenceNo);
}
}
And finally the AutoMapper use-case:
CableID cableID = new CableID("A1", "B1", 2);
Mapper.CreateMap<CableID, CableIDDTO>()
.ForMember(dest => dest.SequenceNo, opt => opt.Ignore());
CableIDDTO dto = Mapper.Map<CableID, CableIDDTO>(cableID);
dto.SequenceNo = 2 when since I had set the Ignore() it should be 0.
This is because AutoMapper is finding this CableIDDTO constructor:
public CableIDDTO(string panelID1, string panelID2, int sequenceNo)
and calling it, setting sequenceNo. I'm not exactly sure how or why it's doing that--i'll continue to dig.
You can fix this by calling .ConstructUsing and telling AutoMapper to use the no-args constructor:
Mapper.CreateMap<CableID, CableIDDTO>()
.ConstructUsing((Func<CableID, CableIDDTO>)(src => new CableIDDTO()))
.ForMember(dest => dest.SequenceNo, opt => opt.Ignore());
Upon further research, this looks like a feature in AutoMapper that tries to match up source property names with destination constructors. Since your destination type (CableIDDTO) had a constructor that perfectly matched up with several property names on the source (panelID1, panelID2, sequenceNo), that constructor was called.
Another way to disable this feature is to call DisableConstructorMapping:
Mapper.Configuration.DisableConstructorMapping()

Is there a standard naming convention for the properties/methods of a node/relationship class when working with Neo4jClient?
I'm following this link Neo4jClient - Retrieving relationship from Cypher query to create my relationship class
However, there are certain properties of my relationship which i can't get any value despite the relationship having it. While debugging my code, i realized certain properties was not retrieved from the relationship when creating the relationship object.
this is my relationship class
public class Creates
{
private string _raw;
private int _sourcePort;
private string _image;
private int _DestinationPort;
private int _eventcode;
private string _name;
private string _src_ip;
private int _src_port;
private string _dvc;
private int _signature_ID;
private string _dest_ip;
private string _computer;
private string _sourceType;
private int _recordID;
private int _processID;
private DateTime _time;
private int _dest_port;
public string Raw { get { return _raw; } set { _raw = value; } }
public int SourcePort { get { return _sourcePort; } set { _sourcePort = value; } }
public string Image { get { return _image; } set { _image = value; } }
public int DestinationPort { get { return _DestinationPort; } set { _DestinationPort = value; } }
public int Eventcode { get { return _eventcode; } set { _eventcode = value; } }
public string Name { get { return _name; } set { _name = value; } }
public string Src_ip { get { return _src_ip; } set { _src_ip = value; } }
public int Src_port { get { return _src_port; } set { _src_port = value; } }
public string DVC { get { return _dvc; } set { _dvc = value; } }
public int Signature_ID { get { return _signature_ID; } set { _signature_ID = value; } }
public string Dest_ip { get { return _dest_ip; } set { _dest_ip = value; } }
public string Computer { get { return _computer; } set { _computer = value; } }
public string SourceType { get { return _sourceType; } set { _sourceType = value; } }
public int RecordID { get { return _recordID; } set { _recordID = value; } }
public int ProcessID { get { return _processID; } set { _processID = value; } }
public DateTime Indextime { get { return _time; } set { _time = value; } }
public int Dest_port { get { return _dest_port; } set { _dest_port = value; } }
}
This is another class
public class ProcessConnectedIP
{
public Neo4jClient.RelationshipInstance<Pivot> bindto { get; set; }
public Neo4jClient.Node<LogEvent> bindip { get; set; }
public Neo4jClient.RelationshipInstance<Pivot> connectto { get; set; }
public Neo4jClient.Node<LogEvent> connectip { get; set; }
}
This is my neo4jclient query to get the relationship object
public IEnumerable<ProcessConnectedIP> GetConnectedIPs(string nodeName)
{
try
{
var result =
this.client.Cypher.Match("(sourceNode:Process{name:{nameParam}})-[b:Bind_IP]->(bind:IP_Address)-[c:Connect_IP]->(connect:IP_Address)")
.WithParam("nameParam", nodeName)
.Where("b.dest_ip = c.dest_ip")
.AndWhere("c.Image=~{imageParam}")
.WithParam("imageParam", $".*" + nodeName + ".*")
.Return((b, bind, c, connect) => new ProcessConnectedIP
{
bindto = b.As<RelationshipInstance<Creates>>(),
bindip = bind.As<Node<LogEvent>>(),
connectto = c.As<RelationshipInstance<Creates>>(),
connectip = connect.As<Node<LogEvent>>()
})
.Results;
return result;
}catch(Exception ex)
{
Console.WriteLine("GetConnectedIPs: Error Msg: " + ex.Message);
return null;
}
}
This is the method to read the results
public void MyMethod(string name)
{
IEnumerable<ProcessConnectedIP> result = clientDAL.GetConnectedIPs(name);
if(result != null)
{
var results = result.ToList();
Console.WriteLine(results.Count());
foreach (ProcessConnectedIP item in results)
{
Console.WriteLine(item.Data.Src_ip);
Console.WriteLine(item.bindto.StartNodeReference.Id);
Console.WriteLine(item.bindto.EndNodeReference.Id);
Console.WriteLine(item.connectto.StartNodeReference.Id);
Console.WriteLine(item.connectto.EndNodeReference.Id);
Node<LogEvent> ans = item.bindip;
LogEvent log = ans.Data;
Console.WriteLine(log.Name);
Node<LogEvent> ans1 = item.connectip;
LogEvent log1 = ans1.Data;
Console.WriteLine(log1.Name);
}
}
}
Somehow, i'm only able to populate the relationship object with src_ip/src_port/dest_ip/dest_port values. the rest are empty.
Is there any possible reason why? I've played with upper/lower cases on the properties names but it does not seem to work.
This is the section of the graph im working with
This is the relationship properties sample:
_raw: Some XML dataSourcePort: 49767Image: C:\Windows\explorer.exeDestinationPort: 443EventCode: 3Name: Bind
IPsrc_ip: 172.10.10.104dvc: COMPUTER-NAMEsrc_port:

13405621ProcessId: 7184_time: 2017-08-28T15:15:39+08:00dest_port: 443
I'm not entirely sure how your Creates class is ever populated, in particular those fields - as your Src_port property doesn't match the src_port in the sample you provided (case wise).
I think it's probably best to go back to a super simple version. Neo4jClient will map your properties to the properties in the Relationship as long as they have the same name (and it is case-sensitive).
So start with a new Creates class (and use auto properties - it'll make your life a lot easier!)
public class Creates
{
public string Computer { get; set; }
}
Run your query with that and see if you get a result, then keep on adding properties that match the name and type you expect to get back (int, string etc)
It seems that i have to give neo4j node/relationship property names in lowercase and without special characters at the start of the property name, in order for the above codes to work.
The graph was not created by me at the start thus i had to work on it with what was given. I had to get the developer who created the graph to create the nodes with lowercases in order for the above to work.
I'm having a class with only private fields and their public getter-setters. I need to convert class object into JSON String hence I'm using JSON.Net.
Following is a simple snippet to convert class object into a JSON string.
MyClass obj = new MyClass();
string json = JsonConvert.SerializeObject(obj);
Console.WriteLine(json);
But the method SerializeObject throws StackOverflowException at field in MyClass of type DateTime. What's happening here?
Update
Following is how MyClass looks like (as it is, I don't mind sharing the actual class)
class MyClass
{
private int _Model;
public int Model
{
get
{
return _Model;
}
set
{
_Model = value;
}
}
private long _ProductionControlNumber;
public long ProductionControlNumber
{
get
{
return _ProductionControlNumber;
}
set
{
_ProductionControlNumber = value;
}
}
private DateTime _ProductionDate;
public DateTime ProductionDate
{
get
{
return _ProductionDate;
}
set
{
_ProductionDate = value;
}
}
private DateTime _TestDate;
public DateTime TestDate
{
get
{
return _TestDate;
}
set
{
_TestDate = value;
}
}
private DateTime _TestStartTime;
public DateTime TestStartTime
{
get
{
return _TestStartTime;
}
set
{
_TestStartTime = value;
}
}
private TimeSpan _TestDuration;
public TimeSpan TestDuration
{
get
{
return _TestDuration;
}
set
{
_TestDuration = value;
}
}
public DateTime TestEndTime
{
get
{
//TODO Perform start end time computing logic.
return TestEndTime;
}
}
private int _TestBed;
public int TestBed
{
get
{
return _TestBed;
}
set
{
_TestBed = value;
}
}
private long _EngineSerial;
public long EngineSerial
{
get
{
return _EngineSerial;
}
set
{
_EngineSerial = value;
}
}
private Single _FuelSpecificGravity;
public Single FuelSpecificGravity
{
get
{
return _FuelSpecificGravity;
}
set
{
_FuelSpecificGravity = value;
}
}
private long _FuelConsume100;
public long FuelConsume100
{
get
{
return _FuelConsume100;
}
set
{
_FuelConsume100 = value;
}
}
private long _FuelConsume110;
public long FuelConsume110
{
get
{
return _FuelConsume100;
}
set
{
_FuelConsume100 = value;
}
}
private int _TemporaryRPM;
public int TemporaryRPM
{
get
{
return _TemporaryRPM;
}
set
{
_TemporaryRPM = value;
}
}
private int _PermanentRPM;
public int PermanentRPM
{
get
{
return _PermanentRPM;
}
set
{
_PermanentRPM = value;
}
}
private Single _RatedPower;
public Single RatedPower
{
get
{
return _RatedPower;
}
set
{
_RatedPower = value;
}
}
private int _RatedSpeed;
public int RatedSpeed
{
get
{
return _RatedSpeed;
}
set
{
_RatedSpeed = value;
}
}
private double _PulleyDiameter;
public double PulleyDiameter
{
get
{
return _PulleyDiameter;
}
set
{
_PulleyDiameter = value;
}
}
private double _RopeDiameter;
public double RopeDiameter
{
get
{
return _RopeDiameter;
}
set
{
_RopeDiameter = value;
}
}
private Single _FullLoad;
public Single FullLoad
{
get
{
return _FullLoad;
}
set
{
_FullLoad = value;
}
}
}
Also, I'll have another class which will have MyClass type field (along with its own similar set of fields), which is going to be converted into JSON string too, and that shouldn't be a problem since JSON.Net is said to support that situation too.
Note: I'm new to C# but I've previously worked with JSON in Java, where I get to play with JSONObject and JSONArray, and they were pretty straight forward.
It looks like your TestEndTime property's getter references itself. Therefore when Json.NET tries to serialize it, it recursively accesses itself and causes the StackOverflowException.
Hope that helps!
I have these classes:
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>();
}
I want to find all the zones in a Zoneset that have a zone member with a specific value for a property in the MembersList.
I know something like this will work - in this case I am searching on the WWPN property:
// 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);
}
}
Is there a way to use LINQ to do the entire thing? I am not sure what the terminology would be in database terms.
This small query should be all you need:
var myZoneList = myZoneSet.ZoneList
.Where(z => z.Any(member => member.MemberWWPN == inputWWPN))
.ToList();
Try this -
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();
I hope this will help.
As I have already done, I have this piece of code:
private string opt;// create a property
public string optionInterval
{
get
{
return opt;
}
set
{
opt = value;
}
}
How can I change the opt to an integer?
Especially in the set part?
public int optionInterval { get; set; }
Using Auto-Implemented Properties
Here's a working version of GianT971's answer:
private int opt;
public string optionInterval
{
get
{
return opt.ToString();
}
set
{
opt = Convert.ToInt32(value);
}
}
private int opt;
public string optionInterval
{
get
{
return opt.ToString();
}
set
{
opt = Convert.ToInt32(value);
}
}
Here are two simple classes to illustrate my question:
class Widget
{
private int _widgetID;
public int WidgetID
{
get { return _widgetID; }
set { _widgetID = value; }
}
private int _categoryID;
public int CategoryID
{
get { return _categoryID; }
set { _categoryID = value; }
}
private string _widgetName;
public string WidgetName
{
get { return _widgetName; }
set { _widgetName = value; }
}
}
And them the second class:
class WidgetCategory
{
private int _widgetCategoryID;
public int WidgetCategoryID
{
get { return _widgetCategoryID; }
set { _widgetCategoryID = value; }
}
private Widget[] _widgets;
public Widget[] Widgets
{
get { return _widgets; }
set { _widgets = value; }
}
private string _widgetCategoryName;
public string WidgetCategoryName
{
get { return _widgetCategoryName; }
set { _widgetCategoryName = value; }
}
}
How would I handle this situation in the most efficient way?
Also, so you know, I will need to nest other classes the same way below the Widget class.
You should create a read-only property of type System.Collections.ObjectModel.Collection<Widget>.
Collection properties should be read only
Use Collection<T>
