HI,

var abc = (from d in Model.Candidates select d.Candidate_ID).ToList();

In this var abc, i am getting 15 candidate Id's.
Now I need to split the 15 candidates into 3 parts and assign to 3 different Var's.

Please help me with the Linq queries.

What I have tried:

var abc = (from d in Model.Candidates select d.Candidate_ID).ToList();

If i understand you well...

C#

var a1 = Model.Candidates
    .Select(d=> d.Candidate_ID)
    .Take(5)
    .ToList();

var a2 = Model.Candidates
    .Select(d=> d.Candidate_ID)
    .Skip(5)
    .Take(5)
    .ToList(); 

var a3 = Model.Candidates
    .Select(d=> d.Candidate_ID)
    .Skip(10)
    .Take(5)
    .ToList();

In case, you want to create custom pagination, you can achieve that by creating generic method. See:

C#

void Main()
{
	List<Candidate> Candidates = GetCandidates();
	
	int j = 5;
	for(int i = 0; i<Candidates.Count; i+=j)
	{
		var data = GetPortion<Candidate>(Candidates, d=>d.Candidate_ID, i, j).ToList();
		data.Dump();
	}
		
}

// Define other methods and classes here
class Candidate
{
	public Guid Candidate_ID {get; set;}
}

IEnumerable<T> GetPortion<T>(IEnumerable<T> list, Func<T, object> orderByField, int curr_val, int NoOfRecordsToGet) where T: class
{
	return list.OrderBy(orderByField).Skip(curr_val).Take(NoOfRecordsToGet);
}


List<Candidate> GetCandidates()
{
	List<Candidate> candies = new List<Candidate>();
	for(int i = 0; i<28; i++)
		candies.Add(new Candidate(){Candidate_ID = Guid.NewGuid()});
	return candies;
}
