Cannot implicitly convert type string to int

Question

    Console.WriteLine (\"Please enter some numbers\");
        int sum = 0;
        for(;;)
        {
            string input = Console.ReadLine ();
            if

I would rewrite this entirely (Your original error was because you were trying to add a string to an int, and not the parsed input as an int)

Console.WriteLine ("Please enter some numbers");
int sum = 0;

while (true)
{
    int parsedInput = 0;
    string input = Console.ReadLine();
    if (!string.IsNullOrEmpty(input) && int.TryParse(input, out parsedInput))
    {
        sum += parsedInput;
        Console.WriteLine (sum);
    }
    else
    break;
}
