How to call custom methods in C#?

To define a custom method in C#, use the following syntax −

<Access Specifier> <Return Type> <Method Name>(Parameter List) {    Method Body }

To call a custom method, try to run the following code. It has the checkPalindrome() method which is called to checker whether the binary representation is Palindrome or not −

Example

 Live Demo

using System; public class Demo {    public static long funcReverse(long num) {       long myRev = 0;       while (num > 0) {          myRev <<= 1;          if ((num & 1) == 1)          myRev ^= 1;          num >>= 1;       }       return myRev;    }    public static bool checkPalindrome(long num) {       long myRev = funcReverse(num);       return (num == myRev);    }    public static void Main() {       // Binary value of 5 us 101       long num = 5;       if (checkPalindrome(num))       Console.WriteLine("Palindrome Number");       else       Console.WriteLine("Not a Palindrome Number");    } }

Output

Palindrome Number
