C# এ একটি অ্যারেতে উপস্থিত মোট উপাদানের সংখ্যা

একটি অ্যারেতে উপস্থিত মোট উপাদানের সংখ্যা পেতে, কোডটি নিম্নরূপ -

উদাহরণ

using System;
public class Demo {
   public static void Main() {
      string[] products = { "Electronics", "Accessories", "Clothing", "Toys", "Clothing", "Furniture" };
      Console.WriteLine("Products list...");
      foreach(string s in products) {
         Console.WriteLine(s);
      }
      Console.WriteLine("Array length = "+products.GetLength(0));
      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")));
   }
}

Array length = 6

One or more products begin with the letter 'C'? = True
One or more planets begin with 'D'? = False
One or more products begin with the letter 'T'? = True
One or more planets begin with 'E'? = True

উদাহরণ

আসুন আরেকটি উদাহরণ দেখি -

using System;
public class Demo {
   public static void Main() {
      string[] products = new string[] { };
      Console.WriteLine("Array length = "+products.GetLength(0));
      Console.WriteLine("Is the array having fixed size? = " + products.IsFixedSize);
      Console.WriteLine("Is the array read only? = " + products.IsReadOnly);
   }
}
