Question

Can anybody help me with this?:
I’m trying call a method from a my class “numbers” to show that if the entered number is over 50, on button click a message box shows displaying “high” but if it’s below 50 it displays “low”.
I can’t figure out what i’m doing wrong here.
This is the code from my class:

    private int number; 
    private string getNumber(int num)
    {

        number = num;
        return number.ToString();
    }

        public int numProperty
    {
        get { return number; }
        set { number = value; }
    }

     public void isHighorlow()
        {    
            if (number >=50)
            {

            }
            else
            {
                return;
            }

        }

Note: the int “number” is property that gets it’s value from a text box too.
& here is the code from my form:

     numbers info = new numbers();
     private void Btn_Click(object sender, EventArgs e)
    { 
      info.numProperty = Convert.ToInt32(numberBOX.Text);
      info.isHighorlow = Messagebox.Show = ("High");
    }

I know that I’ve not added the “low” bit yet because i’m still trying to see how this works. Sorry if it seems confusing as i’m still learning c#.
I get the error message: cannot assign isHighorlow because it’s part of a method group.
And I also realise it’s much easier if I just do an if statement on the textbox, but I’m practising Classes and Methods so I’m trying to do it this way.
thanks.

Answer 1

IsHighOrLow should be as follows

    public bool isHighorlow()
    {    
        if (number >=50)
        {

           return true;
        }
        else
        {
            return false;
        }

    }

And in button click

if (info.isHighorlow){
//say high
} else
{
// say low
}
