Working with Lists
Suppose you have a List that you want to make another List from? This could be useful for an API when serializing Json from an object prior to sending it to a mobile app.
public class ListExample
{
public static List GetAuthorSelect()
{
List authorSelect = new List();
List author = new Data.AccessLayer.GetAuthors();
{
//create and copy the items we want to into a light list
authorSelect = author.ConvertAll(x => new AuthorSelect
{
Id = x.Id,
Name = x.Name
});
}
return authorSelect;
}
//this method shows the equivalent using the traditional for loop
public static List GetAuthorSelectLoop()
{
List authorSelect = new List();
List author = new Data.AccessLayer.GetAuthors();
if (author != null)
{
for (int i = 0; i < author.Count; i++)
{
authorSelect.Add(new AuthorSelect()
{
Id = author[i].Id,
Name = author[i].Name
});
}
}
return authorSelect;
}
}
public class AuthorSelect
{
public int Id { get; set; }
public string Name { get; set; }
}
public class Author
{
public int Id { get; set; }
public string Slug { get; set; }
public string Name { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Nickname { get; set; }
public string Url { get; set; }
public string Description { get; set; }
}
