How do we call a C# method recursively?
To call a C# method recursively, you can try to run the following code. Here, Factorial of a number is what we are finding using a recursive function display().
If the value is 1, it returns 1 since Factorial is 1.
if (n == 1) return 1;
If not, then the recursive function will be called for the following iterations if 1you want the value of 5!
Interation1: 5 * display(5 - 1); Interation2: 4 * display(4 - 1); Interation3: 3 * display(3 - 1); Interation4: 4 * display(2 - 1);
The following is the complete code to call a C# method recursively.
Example
using System; namespace MyApplication { class Factorial { public int display(int n) { if (n == 1) return 1; else return n * display(n - 1); } static void Main(string[] args) { int value = 5; int ret; Factorial fact = new Factorial(); ret = fact.display(value); Console.WriteLine("Value is : {0}", ret ); Console.ReadLine(); } } }
Output
Value is : 120
