Issue in consuming a asmx web method

Question

I am creating a simple asmx web service and trying to consume them. Below is the asmx web service

public class AddTwoNumbers : System.Web.Services.WebService
{

    [WebMethod]
    public int GetSum(int a, int b)
    {
        return  a + b;
    }
}

This is the Windows Console application where I am consuming the service that was created

 namespace TestASMXService
 {
 class Program
 {
    static void Main(string[] args)
    {
        AddingNumber.AddTwoNumbers add = new AddingNumber.AddTwoNumbers();
        Console.Write("First Number:");
        int firstNum = Convert.ToInt32(Console.ReadLine());
        Console.Write("Second Number:");
        int secNum = Convert.ToInt32(Console.ReadLine());
        Console.Write ("The Sum is:",add.GetSum(firstNum, secNum));
        Console.ReadLine();
    }
}

It receives the user inputs and does not return any result or throws any error

Can anyone please tell me what I am missing here.

Answer 1

You are trying to pass an argument in the Console.Write, but do not have a placeholder for it in the format string. The method GetSum will therefore not be called.

Change it to:

Console.Write("The Sum is: {0}", add.GetSum(firstNum, secNum));
