New Project in Visual Studio giving Error -

Daniel Hunt

I am having difficulty understanding the layout of code for these simple programs. If someone could take a look and point me in the right direction I would appreciate it. The simple code is attached and the error is below:

Severity Code Description Project File Line Suppression State
Error CS0106 The modifier 'static' is not valid for this item ConsoleApp2 C:\Users\admin\source\repos\ConsoleApp2\ConsoleApp2\Program.cs 9 Active

Severity Code Description Project File Line Suppression State
Warning CS8321 The local function 'IfStatement' is declared but never used ConsoleApp2 C:\Users\admin\source\repos\ConsoleApp2\ConsoleApp2\Program.cs 9 Active

Accepted answer
What you want to do with your program? You cannot create method under method.

:) My goodness. Thanks!!

I also changed the Output Type under the Project > Properties to that of a “Class Library”.

Thank you Amit!! Thanks Dileep!

What Amit says is correct. The issue is with the spelling of IfStatement. You are calling IfStatement. Once that is corrected the code will compile.

Show your current code. What error you are getting?

Thanks for trying, but that doesn't work. Multiple errors.

You have to split both the functions to make it workable
using System;

namespace ConsoleApp2
{
    class Program
    {
        static void Main(string[] args)
        {
            IfStatememt(args);
        }

            public static void IfStatement(string[] args)
            {
                if (args.Length == 0)
                {
                    Console.WriteLine("No arguments");
                }
                else
                {
                    Console.WriteLine("One or more arguments");
                }
        }
    }

I got more errors with that. I added the system and console info and it still errored.

I'm just trying to run code through Visual Studio to see if I can do it and get it to work. I've been studying the statements here:

https://docs.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/statements

...I understand what you are saying. I thought of that as I was seeing the various errors.
Maybe I am trying to learn too much in one sitting.

I just wanted to take the examples they were providing and try to get them to run through the C# ConsoleApp in Visual Studio.
