解决方案

您可以不写（Q == 1）在C＃中，因为问：是布尔和 1 是 INT 。

①只能相比，另一个布尔前pression，例如真正，假，另一个布尔变量等。

This program is in response to the assignment:

"Create a method named Sum()that accepts any number of integer parameters and displays their sum. Write a Main()method that demonstrates the Sum()method works correctly when passed one, three, five, or an array of 10 integers. Save the program as UsingSum.cs."

from Microsoft® Visual C#® 2008, An Introduction to Object-Oriented Programming, 3e, Joyce Farrell

My code in the "//step 1:" part is getting the CS0019 error, which states that it cannot be applied to operands of type 'bool' and 'int'

I highly suspect there are also other problems with this code, but it's a great improvement over what I had four hours ago...

using System;

public class UsingSum
{
    public static void Main()
    {

        Sum();

    }

    public static void Sum()

  int n;
  int o;
  int p;
  int firstTotal;

  bool s;

  Console.Write("Type the number 1: ");    
  k = Console.ReadLine();
  q = Convert.ToBoolean(k);
  n = Convert.ToInt32(k);

  Console.WriteLine();

  if(q == 1)
        {
           Console.WriteLine("Input accepted.");
        }

  }                                         
 }  
}  

解决方案

You can't write (q == 1) in C#, because q is a bool and 1 is an int.

q can only be compared to another boolean expression, e.g. true, false, another boolean variable, etc.
