Total number of elements present in an array in C#
To get the total number of elements present in an array, the code is as follows −
Example
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")));
}
}Output
This will produce the following output −
Products list... Electronics Accessories Clothing Toys Clothing Furniture 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
Example
Let us see another example −
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);
}
}Output
This will produce the following output −
Array length = 0 Is the array having fixed size? = True Is the array read only? = False
