I can not access Count property of the array but through casting to ICollection !

Question

        int[] arr = new int[5];
        Console.WriteLine(arr.Count.ToString());//Compiler Error
        Console.WriteLine(((ICollection)arr).Count.ToString());//works p         


        

Answer 1

Whilst this doesn't answer your question directly, if you are using .NET 3.5 you can include the namespace;

using System.Linq;

which will then allow you to use a Count() method, similar to when casting your int array as an ICollection.

using System.Linq;

int[] arr = new int[5];
int int_count = arr.Count();

You also then have a whole host of nice functions you can use in Linq too :)
