Returning the first few items from an Array list or IEnumerable collection, like T-Sql top()
I needed to bind the first 5 items in a List<T> to a repeater. Having recently discovered the .Distinct() extension, I had a look through the other methods attached to my List<T> and found .Take(int)
Basic example of using .Take()
string[] allAnimals = "cat,dog,mouse,chicken,cat,dog,elephant,mouse".Split(",".ToCharArray()); foreach (string animal in allAnimals.Take(5)) { Console.WriteLine(animal); } Console.ReadLine();
The output
Only the first 5.
cat dog mouse chicken cat
Example of using .Take() when binding an IEnumerable object to a repeater
HistoricCategoriesRepeater.DataSource = allAnimals.Take(5); HistoricCategoriesRepeater.DataBind();
You may also like to take a look at the .Skip(int) method. It can be used in conjunction with .Take() to help you with paging object data.
