Updating Data in List

Question

I am trying to update the items in a list with user provided parameters. I am using a custom list type AbilityScores. See below:

class AbilityScores
{
    public string Strength { get; set; }
    public string Dexterity { get; set; }
    public string Constitution { get; set; }
    public string Intelligence { get; set; }
    public string Wisdom { get; set; }
    public string Charisma { get; set; }
}

I am trying to add the update a specific part of the list:

if(ability == "Strength"){
            abilityScores.Where(w => w.Strength == "Strength").ToList().ForEach(s => s.Strength = scoreIncrease.ToString());
}

Both ability and scoreIncrease are user provided parameters. Here I am updating the strength attribute. I understand most of what I read here:

c# Update item in list

But I do not understand what w => w.Strength == "Strength" is actually doing. How would I use this in my code? I am really new to C# and lists. Any help would be greatly appreciated.

Answer 1

You don't need the Where at all. It is used when you want to filter somes item by a condition defined by a Predicate

In your case, you want to update the value Strength for all objects.

Using a ForEach is enough

foreach(var s in abilityScores)
{
    s.Strength = scoreIncrease.ToString()
}
