WCF: Object Reference Not Set To Instance Of a an Object

Question

I have a CibilResponse Class that has properties that are of class type (TUEF class). I am trying to assign value to CibilEnquiryEnq.Tuef.Version but i am getting null reference error. Before you mark this question as duplicate let me mention that I have read some of the similar questions and their answers on SO and post which I have initialized tuef in the constructor as you can see in my code. Can you please point out if you can what is it that I am doing wrong?

ICIBIL.cs

[ServiceContract]
public interface ICIBIL
{

    [OperationContract]
    string InsertCibil(CibilResponse cibilResponse);


    [OperationContract]
    string GenerateEnquiry(CibilEnquiry testObj);


}

[DataContract]
public class CibilResponse
{
    [DataMember]
    public string ResponseString { get; set; }
    [DataMember]
    public string Business { get; set; }
    [DataMember]
    public string MkrId { get; set; }
}


[DataContract]
public class CibilEnquiry
{
    [DataMember]
    public TUEF Tuef { get; set; }   

    public CibilEnquiry()
    {
        this.Tuef = new TUEF();
    }

}


    [DataContract]
    public class TUEF
    {
        [DataMember]
        public string SegmentTag { get; set; }
        [DataMember]
        public string Version { get; set; }
        [DataMember]
        public string MemberReferenceNumber { get; set; }        

    }

Appication :

CibilWcfService.CIBIL obj = new CibilWcfService.CIBIL();
CibilWcfService.CibilEnquiry CibilEnquiryEnq = new CibilWcfService.CibilEnquiry();
CibilEnquiryEnq.Tuef.Version = "123";// null reference error here
string res = obj.GenerateEnquiry(CibilEnquiryEnq);

@MohitShrivastava As I have already mentioned I have read that post and upon which I also initialized tuef in constructor but it did not solve my problem. — SamuraiJack, Nov 17 '15 at 04:52

Can you try the below. C# is case sensitive.

using CbilFileReader.CibilWcfService;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {


            CIBIL obj = new CIBIL();
            CibilEnquiry CibilEnquiryEnq = new CibilEnquiry();
            TUEF objtuef = new TUEF();
            objtuef.Version = "123";
            CibilEnquiryEnq.Tuef = objtuef;
            string res = obj.GenerateEnquiry(CibilEnquiryEnq);
        }
    }
}

Yes am editing the response. I felt Tuef Class is part of CibilEnquiryEnq. – Baskar Rao Nov 17 '15 at 04:56
`The type or namespace Tuef could not be found..` `CibilEnquiry does not exist in current context.` – SamuraiJack Nov 17 '15 at 04:58
I am not able to find `Tuef` I am getting `type or namespace Tuef could not be found` at `Tuef objtuef=new Tuef();` – SamuraiJack Nov 17 '15 at 05:03
Can you share the Reference.cs file which gets added after adding the service reference. can you try by adding a using CibilWcfService; statement in your application – Baskar Rao Nov 17 '15 at 05:06
Here you go. This should work – Baskar Rao Nov 17 '15 at 05:25
After adding `CibilWcfService.` as prefix ..Yes it worked! I wonder if there is a better way to assign values other than this. But Thanks it answered the question. – SamuraiJack Nov 17 '15 at 05:40

This might do the trick for you

CibilWcfService.CIBIL obj = new CibilWcfService.CIBIL();
CibilWcfService.CibilEnquiry CibilEnquiryEnq = new CibilWcfService.CibilEnquiry();
CibilWcfService.CibilEnquiry.Tuef ObjTUEF = new CibilWcfService.CibilEnquiry.Tuef();
ObjTUEF.Version="123";
CibilEnquiryEnq.Tuef = ObjTUEF;
string res = obj.GenerateEnquiry(CibilEnquiryEnq);
