जांचें कि किसी ऐरे का आकार निश्चित है या नहीं सी #

यह जांचने के लिए कि किसी सरणी का आकार निश्चित है या नहीं, नीचे दिए गए कोड को आजमाएं -

उदाहरण

using System;
public class Demo {
   public static void Main(){
      string[] products = new string[] { "Electronics", "Accessories", "Clothing", "Toys", "Clothing", "Furniture" };
      Console.WriteLine("Products list...");
      foreach(string s in products){
         Console.WriteLine(s);
      }
      Console.WriteLine("Is the products Accessories in the array? = {0}",
         Array.Exists(products, ele => ele == "Accessories"));
      Console.WriteLine("Is the products Stationery in the array? = {0}",
         Array.Exists(products, ele => ele == "Stationery"));
      Console.WriteLine("\nOne or more products begin with the letter 'C'? = {0}",
         Array.Exists(products, ele => ele.StartsWith("C")));
      Console.WriteLine("One or more planets begin with 'D'? = {0}",
         Array.Exists(products, ele => ele.StartsWith("D")));
      Console.WriteLine("One or more products begin with the letter 'T'? = {0}",
         Array.Exists(products, ele => ele.StartsWith("T")));
      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);
   }
}
