In this program, You will learn how to find the sum of even digits of a number in C#.

```
201454 = 2 + 4 + 4 => 10
693322 = 6 + 2 + 2 => 10
```

## Example: How to find the sum of even digits of a number in C#.

```
using System;
public class Program
{
public static void Main(string[] args)
{
int n, r, s = 0;
Console.Write("Enter a number:");
n = Convert.ToInt32(Console.ReadLine());
while (n > 0)
{
r = n % 10;
if (r % 2 == 0){
s = s + r;
}
n = n / 10;
}
Console.WriteLine("Sum of even digits:" + s);
}
}
```

#### Output:

```
Enter a number:2345
Sum of even digits:6
```
