Re: C# beginner need some pro advice

VBScript mostly and VB. Completely different languages.

What do I need to pass for example the variable ReadName and pick just that one up into the main method. As you can see I have no problem creating new instances of the class and pass the entire method ReadInput to the main.

Re: C# beginner need some pro advice

OK, but how would you have made a sub in vb, to send it say 2 parameters, and return the sum of them as a result?

(c# while different is not as hugely different in this respect)

Re: C# beginner need some pro advice

Perhaps it is something like this you want?
Will this clarify your mind?

C# Syntax (Toggle Plain Text)
class Product
{
    public string ReadName; //name of the product
    //other fields here
 
    public void ReadInput()
    {
        Console.Write(" Product name: ");
        string ReadName = Console.ReadLine();
        //other things here
    }
    //other methods here
}
 
class MyConsoleApp
{
    static void Main(string[] args)
    {
        Product objGet = new Product();
        objGet.ReadInput();
 
        //now here I can use
        Console.WriteLine("Name of product : {0}", objGet.ReadName);
 
        Console.ReadLine();
    }
}
class Product
{
    public string ReadName; //name of the product
    //other fields here

    public void ReadInput()
    {
        Console.Write(" Product name: ");
        string ReadName = Console.ReadLine();
        //other things here
    }
    //other methods here
}

class MyConsoleApp
{
    static void Main(string[] args)
    {
        Product objGet = new Product();
        objGet.ReadInput();

        //now here I can use
        Console.WriteLine("Name of product : {0}", objGet.ReadName);

        Console.ReadLine();
    }
}

Re: C# beginner need some pro advice

Yes thanks!

I dont know the difference between set public variable as you did and a method. But it seem to be a good start.

I will work with this a bit and send you a feedback here!
Thanks

Re: C# beginner need some pro advice

No errors, but no one of the public variables can be assigned to any values. No matter if I try to change data types. I dont know whats wrong. My code here should do a simple calculation and print out the results.

C# Syntax (Toggle Plain Text)
   class Product
    {
        public string ReadName; //name of the product
        public double ReadPrice; //price of the product
        public int UnitCount; //Unit count
        public string FoodItem; //Unit count
 
        public void ReadInput()
        {
            Console.Write(" Product name: ");
            string ReadName = Console.ReadLine();
            Console.Write(" Product price: ");
            double ReadPrice = Convert.ToDouble(Console.ReadLine());
            Console.Write(" Unit count: ");
            int UnitCount = Convert.ToInt32(Console.ReadLine());
            Console.Write(" Food item y/n: ");
            string FoodItem = Console.ReadLine();
        }
 
        static void Main(string[] args)
        {
            Product objGet = new Product();
            objGet.ReadInput();
 
                 double iPrice = objGet.ReadPrice;
                 int iCount = objGet.UnitCount;
 
            double iCalc = iPrice * iCount;
 
            Console.Write(" Price total: {0}", iCalc);
 
            Console.ReadLine();
        }
    }
   class Product
    {
        public string ReadName; //name of the product
        public double ReadPrice; //price of the product
        public int UnitCount; //Unit count
        public string FoodItem; //Unit count

        public void ReadInput()
        {
            Console.Write(" Product name: ");
            string ReadName = Console.ReadLine();
            Console.Write(" Product price: ");
            double ReadPrice = Convert.ToDouble(Console.ReadLine());
            Console.Write(" Unit count: ");
            int UnitCount = Convert.ToInt32(Console.ReadLine());
            Console.Write(" Food item y/n: ");
            string FoodItem = Console.ReadLine();
        }

        static void Main(string[] args)
        {
            Product objGet = new Product();
            objGet.ReadInput();

                 double iPrice = objGet.ReadPrice;
                 int iCount = objGet.UnitCount;

            double iCalc = iPrice * iCount;

            Console.Write(" Price total: {0}", iCalc);

            Console.ReadLine();
        }
    }

Re: C# beginner need some pro advice

That is totaly my fault! Not yours!

C# Syntax (Toggle Plain Text)
public void ReadInput()
        {
            Console.Write(" Product name: ");
            string ReadName = Console.ReadLine();
            Console.Write(" Product price: ");
            double ReadPrice = Convert.ToDouble(Console.ReadLine());
            Console.Write(" Unit count: ");
            int UnitCount = Convert.ToInt32(Console.ReadLine());
            Console.Write(" Food item y/n: ");
            string FoodItem = Console.ReadLine();
        }
public void ReadInput()
        {
            Console.Write(" Product name: ");
            string ReadName = Console.ReadLine();
            Console.Write(" Product price: ");
            double ReadPrice = Convert.ToDouble(Console.ReadLine());
            Console.Write(" Unit count: ");
            int UnitCount = Convert.ToInt32(Console.ReadLine());
            Console.Write(" Food item y/n: ");
            string FoodItem = Console.ReadLine();
        }

Can you see why?
I redefined ReadName as a local string variable of the method ReadInput!
Console.Write(" Product name: ");
string ReadName = Console.ReadLine();
should be
Console.Write(" Product name: ");
ReadName = Console.ReadLine();
do the same for the rest of your variables.
Sorry for the trouble, but do you know the definition of an expert?
An expert is a person who has made all the possible mistakes...

Re: C# beginner need some pro advice

Thanks again...
That was it !

I agree, and I must do a lot of mistakes myself to learn this. It is fun language but a little bit hard sometimes.

I am sure I will be back here soon..

best regards
Torbjorn
