Method based is going to be used on something that is using IEnumerable<T> most of the time, and you should be able to IntelliSense when you can use a Linq method. The method() can use lambada.
https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/concepts/linq/query-syntax-and-method-syntax-in-linq
To be honest, Resharper taught me how to use Linq. :) It would evaluate code and suggest a change, and 9 times out of 10, I would just go with the suggested change. That lead to me knowing when I could use Linq in various ways and made me curious, experiment
and Resharper would make the corrections, when I would use Google and look up a Linq method about just what it is and how can I use it.
You can do something like this too.
var list = GetSomeList().Where( a => a.Name.contains ("rajemessage").ToList().
if the method() is returning a collection, then you can apply Linq to the collection that is returned out of the method().
public ProjectViewModels GetProjectsByUserId(string userid)
{
var vm = new ProjectViewModels {Projects = new List<ProjectViewModels.Project>()};
var dtos = _webApi.GetProjsByUserIdApi(userid).ToList();
vm.Projects.AddRange(dtos.Select(dto => new ProjectViewModels.Project()
{
ProjectId = dto.ProjectId,
ClientName = dto.ClientName,
ProjectName = dto.ProjectName,
Technology = dto.Technology,
ProjectType = dto.ProjectType,
StartDate = dto.StartDate,
EndDate = dto.EndDate,
Cost = dto.Cost
}).ToList());
return vm;
}
public DtoTask GetTaskById(int id)
{
var dto = new DtoTask();
using (var context = new ProjectManagementContext(_options))
{
var task = (context.Tasks.Where(a => a.TaskId == id)).SingleOrDefault();
if (task == null) return dto;
dto.TaskId = task.TaskId;
dto.TaskName = task.TaskName;
dto.Note = task.Note;
dto.StartDate = task.StartDate;
dto.EndDate = task.EndDate;
dto.ResourceId = task.ResourceId;
dto.ProjectId = (int)task.ProjectId;
dto.TaskDuration = task.TaskDuration;
dto.TaskSpent = task.TaskSpent;
dto.Status = task.Status;
}
return dto;
}
