একটি অ্যারে শুধুমাত্র পঠনযোগ্য কিনা তা পরীক্ষা করতে, নীচের কোডটি চেষ্টা করুন −
উদাহরণ
using System; public class Demo { public static void Main(){ string[] products = new string[] { }; Console.WriteLine("One or more planets begin with 'E'? = {0}", Array.Exists(products, ele => ele.StartsWith("E"))); Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize); Console.WriteLine("Is the array read only? = " + products.IsReadOnly); } }
