I have an ArrayList that contains multiple String[] (String arrays).
Each String[] contains a key: name
What I want to do is sort the ArrayList based on the value of name.
Using Array.Sort did not work because it cannot compare String[]. How can I sort the ArrayList based on the value of name that is within the String[]?
In LINQ:
var ordered = arrayList.Cast<String[]>().OrderBy(ar => arr[0]);
Normally it's better to use a strong typed List<String[]> instead of an ArrayList. When you say key it sounds as if you want to have a list of strings for each unique key. Then a Dictionary<String, String[]> would be the best choice.
IEnumerable<T>. You need arrayList.Cast<string[]>.OrderBy(arr => arr[0]);
ar represent in this example? the string[] within the list?
ar(r) => arr[0]You should be using a List<string[]>. It supports everything that ArrayList does, and it is strongly typed.
Using a List<string[]>:
IEnumerable<string[]> sorted = myList.OrderBy(s => s[0]);
Try this
ArrayList arr = new ArrayList();
arr.ToArray().OrderBy(p => p);
p => p[0]?Use Array.Sort(Array,IComparer) and write your own Comparer that looks for your key in your String[] and compare them.
You can create an IComparer an use
public virtual void Sort(
IComparer comparer
)
You can pass to Array.Sort either a delegate or a class implementing an interface that implements the custom comparison you need.
See some examples http://bytes.com/topic/c-sharp/answers/235679-two-dimension-array-sort.
Array[]'s? If so, you could always use LINQ.ArrayListorList? The sorting problem still exists no?List.
