Assign a List object to another List in c#

I have following classes:

public class ProviderQualification
{
    public List<ProviderDetail> ProviderDetails { get; set; }
}
public class ProviderDetail
{
    public string ProviderName { get; set; }
    public string ServiceableOffers { get; set; }
}
public class ProviderQualificationTimeViewModel
{
    public List<ProviderQualificationDetail> ProviderQualificationDetails { get; set; }
}
public class ProviderQualificationDetail
{
    public string ProviderName { get; set; }
    public string TotalServiceableOffers { get; set; }
}

I have ProviderQualification object populated with List<ProviderDetail>.

ProviderQualification providerQualification = reporting.GetProviderQualification();

Now I want to copy this list to my List<ProviderQualificationDetail>. How would I do that?

In my opinion, @zaria want to select distinct ProviderName and total ServiceableOffers. If she has ProviderQualification class why she wants to bind to ProviderQualificationDetail?

 List<ProviderQualificationDetail> list=providerQualification.ProviderDetails.GroupBy(x => x.ProviderName)
                                          .Select(x=>new ProviderQualificationDetail{
                                                   ProviderName =x.Key,
                                                   TotalServiceableOffers=Sum(y=>y.ServiceableOffers) 
                                           }).ToList();

You need a mapping to get from ProviderDetail to ProviderQualificationDetail. For example, if you just want to copy over those values, you can just write it inline like this:

ProviderQualification providerQualification = reporting.GetProviderQualification();

var items = providerQualification.ProviderDetails
            .Select(detail => new ProviderQualificationDetail
                {
                    ProviderName = detail.ProviderName,
                    TotalServiceableOffers = detail.ServiceableOffers
                })
            .ToList();

var viewModel = new ProviderQualificationTimeViewModel
{
    ProviderQualificationDetails = items
};

Using Linq:

List<ProviderQualificationDetail> result = 
         providerQualification.ProviderDetails.Select(
                         q => new ProviderQualificationDetail() 
                                   { 
                                       ProviderName  = q.ProviderName, 
                                       TotalServiceableOffers = q.ServiceableOffers 
                                   }).ToList();

Using Select you project each element in ProviderDetails into a new element of type ProviderQualificationDetail and then Enumerate that into a List.

You can use

Enumerable.Select< TSource, TResult > Method (IEnumerable< TSource >, Func< TSource, TResult >)

For example

List<ProviderQualificationDetail> list = 
providerQualification.ProviderDetails
.Select(x => new ProviderQualificationDetail(){
    ProviderName = x.ProviderName,
    TotalServiceableOffers = x.ServiceableOffers
}).ToList();
