"Expected class, delegate, enum" Code Issue

Question

Getting some errors at least this time I know why..seems like I am not declaring the methods inside my classes I tried rearranging the method and then inserting all my code into a class but Im still getting all those errors in the bottom.

If you guys can tell me how to also avoid this problem in the future that would be great!

Line 75 ends your class, and line 79 ends the namespace. Move those methods to before line 75.

You have semi colons on the lines where you are declaring a method
example on line 80 you have public static void DisplayInstructions(); followed by braces. Remove those semi colons and place your methods into the class

You have code outside class and ... quite a few other errors

tell me how to also avoid this problem in the future that would be great!

Turn on every error msg, editor helps etc. You should see when things start to go wrong straight away, not after writing a few pages of piece of... code. And if you get an error of missing/extra thing, correct the error straight away. Do not wait until you have 100 errors and then start to wonder how to fix 'em.
If the brackets are far away, add a comment to the ending bracket which tells what is that bracket closing. See above how I commented the ending of the class code and the namespace.
Finally write your code with a good editor, like Microsoft's free Visual C# Express. Notepad is a fine editor but it's not for you ;)

I still had the same errors when the methods were before the class but i will try again

Ok with the help of all of you I cut and trimmed down the problems a bit more...I know have 15 errors left and this is what the code looks like. I even moved my methods inside the class and denoted where the class ends and where does the namespace end .

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ProblemGranola

    class GranolaSales

            const double NUMBER_OF_CASES = 5;
            const double ASSOCIATION_FEES = 0.10;
            
            string inputValue;
            int cases,
                bars;

            DisplayInstructions();
            
            cases = GetCases(1);
            bars = GetBarPrice(1);
            

            DisplayResults(int bars, int cases, int ASSOCIATION_FEES)

            Console.ReadKey();
        }

        {

       {
            Console.WriteLine("Please enter the {0} of each bar: ");
            inValue = Console.ReadLine();
            someIntValue = int.Parse(inValue);
            return someIntValue;

            someintValue = int.Parse(inValue);

You are missing 2 closing curly braces at the end. One should close the class, the other should close the namespace.

You are missing 2 closing curly braces at the end. One should close the class, the other should close the name-space.

sorry i didn't copy the entire code I have the bracket where class ends and also the closing bracket for name-space. But I still have errors

ok i fixed all the errors my only problem is the "Debug" option is greyed out , and so is the "green arrow" . What is going on?

here is my revised code:

my only problem is the "Debug" option is greyed out , and so is the "green arrow"

Check Build\Configuration Manager. Configuration should be Debug, not Release.

ok i opened up a new project window and repasted the same code:

... and the same errors too ;)

I regained 16 of the errors here are errors :

Very clear error messages. Like "Error 4 Argument 1: cannot convert from 'string' to 'int' 23 32 ", just fix it. BTW, I had fixed these errors in the previous page.

someIntValue and inValue has not been declared, if u want it in multiple methods, put that as a global variable or pass it in a method as an argument.

GetCases() and GetBarPrice() expects an integer as the argument, u are passing a string.

all these are simple issues, or may be the very basics of errors you can say. just go through what you have written, you will find the solution in the errors itself.
