asp.net mvc - Foreach loop binding all data in first iteration -

guys in asp mvc 4 web application, trying bind education details model candidate model. happens that, on first iteration of foreach loop, binds same data candidates. have been stuck on more 4 hours , can't seem figure out...

in controller :

 if (dsresult.tables[18].rows.count > 0) {  foreach (datarow drrequirededucation in dsresult.tables[18].rows) { var jobdescriptioncode = convert.toint32(drrequirededucation["jobdescriptioncode"].tostring()); var education = new education();  education.educationcode = convert.toint32(drrequirededucation["educationcode"].tostring()); education.educationname = drrequirededucation["educationname"].tostring();  var candidates = candidatepreofferviewmodel.candidates.where(x => x.jobrequisition.jobdescriptioncode == jobdescriptioncode); foreach (var candidate in candidates) {     candidate.jobrequisition.jobdescription.jobdescriptioncode = jobdescriptioncode;     candidate.jobrequisition.jobdescriptioncode = jobdescriptioncode;     candidate.jobrequisition.jobdescription.educations.add(education); }}} 

in candidatepreofferviewmodel model :

public class candidatepreofferviewmodel {     public candidatepreofferviewmodel()     {         this.candidates = new list<candidate>();         this.departmentcandidates = new list<departmentcandidate>();     }      public int selecteddepartmentcode { get; set; }     public string selectedcandidatestatuscode { get; set; }     public list<candidate> candidates { get; set; }     public list<departmentcandidate> departmentcandidates { get; set; } } 

candidate model :

public class candidate {     public candidate()     {         this.educations = new list<education>();         this.experiences = new list<experience>();         this.jobrequisition = new jobrequisition();         this.performances = new list<candidateperformance>();         this.requirededucationforrequisition = new list<education>();     }      .....xyz....     public list<education> educations { get; set; }     public list<experience> experiences { get; set; }     public jobrequisition jobrequisition { get; set; }     public list<candidateperformance> performances { get; set; }     public list<education> requirededucationforrequisition { get; set; } } 

in view :

<span>required:      @foreach (var education in candidate.jobrequisition.jobdescription.educations)     {         <div>-@education.educationname</div>     } </span> 

now problem is, on first iteration sets education 9 candidates , second iteration again adds same education , on, result getting repeated data in picture (education repeated 9 times because there total of 9 candidates, there 3 entries education in db) :

i going nuts trying figure out problem, make day.

in second loop , check if perticular education added candidate

foreach (var candidate in candidates) {

candidate.jobrequisition.jobdescription.jobdescriptioncode = jobdescriptioncode; candidate.jobrequisition.jobdescriptioncode = jobdescriptioncode;

      //check if education added.     var alreadyadded = candidate.jobrequisition.jobdescription.educations.where(e=>e.educationname==education.educationname).firstordefault();      if(alreadyadded!=null)      {       candidate.jobrequisition.jobdescription.educations.add(education);     } }}} 

this .where linq , may need add using system.linq; else can loop thru candidates educations , see if education.educationname present or not;
