manipulating string

foreach (var pizza2 in pizzas)
{
    if (selection <= FoodMenu.pizzas.Count)
    {
        string temp = pizza2.ToString();
        string name = temp.Substring(0, temp.IndexOf(","));
        string toppings = temp.Substring(name.Length, );
        int price = int.Parse((""));
        Pizza pizza = new Pizza(name, toppings, price);
    }
}

i need to separate name from toppings and price to then create an instance of an item ive managed to separate the name but how would I make a substring from the first comma to the £ sign

Angius•8mo ago

I'd probably write a parser instead tbh

jsOP•8mo ago

i need to get the toppings back into a list

Angius•8mo ago

If not that, then split by , first First element will be the name

jsOP•8mo ago

to create my item

Angius•8mo ago

Then split last element by ' ' And the last part of that element will be the price

jsOP•8mo ago

but theres multiple whitespaces before the £ sign

Angius•8mo ago

Yeah, but the last segment will be the price

jsOP•8mo ago

tomato sauce has a space and i dont want to split that

Angius•8mo ago

You just split it to extract the price

var nameAndRest = str.Split(',');
var name = nameAndRest[0];
var rest = nameAndRest[1..];
var priceStr = rest[^1].Split(' ')[^1];

var nameAndRest = str.Split(',');
var name = nameAndRest[0];
var rest = nameAndRest[1..];
var priceStr = rest[^1].Split(' ')[^1];

intPriceTemp = intPriceTemp.Remove(intPriceTemp.IndexOf("£")); intPriceTemp = intPriceTemp.Remove(intPriceTemp.IndexOf(".")); im getting an error am i supposed to have 2 arguments inside .remove i only want to remove that specific character

Look the method up in the documentation, see what the other parameter is

i know now but its still saying my index numbers are invalid

foreach (var pizza2 in pizzas2)
{
    if (selection <= FoodMenu.pizzas.Count)
    {
        string temp = pizza2.ToString();
        string name = temp.Substring(0, temp.IndexOf(","));
        int nameLength = name.Length;
        string toppings = temp.Substring(nameLength, temp.IndexOf("£"));

foreach (var pizza2 in pizzas2)
{
    if (selection <= FoodMenu.pizzas.Count)
    {
        string temp = pizza2.ToString();
        string name = temp.Substring(0, temp.IndexOf(","));
        int nameLength = name.Length;
        string toppings = temp.Substring(nameLength, temp.IndexOf("£"));
