C# / CSharp Tutorial » Data Structure » Array Length 
11.4.1.Use the Length array property
using System; 
 
class MainClass {  
  public static void Main() {  
    int[] nums = new int[10];  
 
    Console.WriteLine("Length of nums is " + nums.Length);  
  
    Console.Write("use Length to initialize nums");
    for(int i=0; i < nums.Length; i++)  
      nums[i= i * i;  
  
    Console.Write("now use Length to display nums");
    Console.Write("Here is nums: ")
    for(int i=0; i < nums.Length; i++)  
      Console.Write(nums[i" ");  
  }  
}
Length of nums is 10
use Length to initialize numsnow use Length to display numsHere is nums: 0 1 4 9 16 25 36 49 64 81 "
