How to Resolve the 'Object Reference Required for Non-Static Method' Error in C#?

Error: "An object reference is required for a non-static field, method, or property..."

Question:

This error occurs because the "volteado" and "siprimo" methods in the provided C# code are non-static, while the "Main" method is static. This means that non-static methods cannot be accessed from the static "Main" method.

Solution:

To solve this problem, the "volteado" and "siprimo" methods need to be declared as static methods. This can be achieved by adding the "static" keyword before the method declaration, like this:

<code class="language-csharp">private static long volteado(long a)

private static bool siprimo(long a)</code>

With this modification, the "volteado" and "siprimo" methods can be accessed from the static "Main" method without throwing an error.
