I have a class as such:
class Item
{
public string eventName{ get; set; }
public string performanceTime { get; set; }
}
and I have two lists of data:
List<string> progName = getProgrammingNames();
List<string> progTimes = getProgrammingTimes()
Inside both string lists are data and I would like to merge them to
List<Item> itemList = new List<Item>();
How can I do it?
Use .Zip to get the items together and then project the Item class:
var result = progName.Zip(progTimes, (name, time) => new Item {
eventName = name,
performanceTime = time }).ToList();
As Zip only returns items with same index if one collection is bigger than other it will be missing those items. In that case you can use a form of full outer join:
var result = from i in Enumerable.Range(0, Math.Max(progName.Count, progTimes.Count))
join n in progName.Select((item, index) => new { item, index }) on i equals n.index into names
from n in names.DefaultIfEmpty()
join t in progTimes.Select((item, index) => new { item, index }) on i equals t.index into times
from t in times.DefaultIfEmpty()
select new Item { eventName = n?.item, performanceTime = t?.item };
getProgrammingNames and getProgrammingTimes do?A simple For loop is not enough?
List<string> progName = getProgrammingNames();
List<string> progTimes = getProgrammingTimes();
if (progName.Count != progTimes.Count)
throw new Exception("2 list counts are different");
List<Item> itemList = new List<Item>();
for (var l_i = 0; l_i < progName.Count; l_i++)
{
itemList.Add(new Item()
{
eventName = progName[l_i],
performanceTime = progTimes[l_i]
});
}
