I'm having a small issue calling in the Icloneable interface
I've told the class I want to use the interface as such:
class UnitClass: ICloneable
and have placed in a function for Cloning
public Object Clone()
{
return this.MemberwiseClone();
}
however for some reason the program is telling me that I have not implemented System.ICloneable.clone() I even tried giving the function the explicit name like so...
public Object System.ICloneable.Clone()
but with little effect, anybody know what I'm doing wrong?
edit: Full class
class UnitClass: ICloneable
{
//-----------------------------------------------------------------------------------------------

public object Clone()

This built fine for me.
public class MyClone : ICloneable
{
public object Clone()
{
return this.MemberwiseClone();
}
}
You don't perhaps want to share any more of your class? Nothing is really jumping out at me.

Now when I execute the query into a list using dapper
Connection conn = new Connection();
OracleConnection connection = conn.GetDBConnection();
myList= connection.Query<Batch>(querySql).ToList();
Now,while debugging, all fields returns the expected values .But, I noticed those fields below are null in myList not empty but really null , but the problem is they aren't null in the database
Bmdrubirique , Sunid, Bmdentrynbre, Bradid ,Cenid
In oracle database those fields are like the following :
CENID is VARCHAR2(3 BYTE)`
Bmhid is VARCHAR2(3 BYTE)
Sunid is NUMBER(38,0)
Bradid is VARCHAR2(3 BYTE)
I don't get it , where did it go wrong? why other fields are properly loaded while those returns null value ?
My default assumption would be that there is a typo in the real code and the constructor is assigning a value from a field to itself. However, frankly: since you have a public Batch() {} constructor, I'm not sure what the benefit of the second one is - it just adds risk of errors. Likewise with the fields and manual properties.
So if this as me, where you currently have (simplified to two properties):
public class Batch
{
private string cendid;
private string bmhfmc;
public Batch() {}
public Batch(string cendid, string bmhfmc)
{
this.cendid = cendid;
this.bmhfmc = bmhfmc;
}
public string Cendid
{
get { return cendid; }
set { cendid = value; }
}
public string Bmhfmc
{
get { return bmhfmc; }
set { bmhfmc = value; }
}
}
I would have literally just:
public class Batch
{
public string Cendid {get;set;}
public string Bmhfmc {get;set;}
}
All of the rest of the code is just opportunities to make coding errors.
Now: the reason that Cendid is null is because: the column is CENID - only one d. This means that dapper isn't even using your custom constructor, because it isn't a perfect match between the constructor and the columns. Ditto the other fields like BRAID vs BRADID.
So the next thing to do is to fix the typos.
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 am new to C# and was asked to create two class definitions (customer and order) using partial code and with the suggested class names, methods, contructors and following an example. I am not sure why I am getting so many errors when I build/debug?
After this is finished, I need to create another program that builds onto this one. Our instructor also asked us not to use validation...
Some of my most common errors are:

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;

{

}
set
{

{

}
set
{

}

{

}
set
{

}
set

}
}

{
get
{
//TODO Perform start end time computing logic.
return TestEndTime;
}
}
private int _TestBed;
public int TestBed

}
set
{

}

}
}
private 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
{

}
}
private int _PermanentRPM;
public int PermanentRPM
{
get
{

}
set
{

}
}
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!
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>
