Question

I’m curious how to write this, if it’s possible, as a lambda expression.

For (int i = 0; i < MyList.Count; i++)
{
    MyMethod(MyList[i].Id, MyList[i].Value);
}

public void MyMethod(string id, string value)
{
   // do kung-fu
}

I’ve seen how I can use lambda expressions to call an object’s methods, but I can’t find one to do it this way.

I realize a loop works just fine. I’m just wondering if it could be done and how.

Answer 1

I wouldn’t use a lambda expression – but I would use a foreach loop:

foreach (var item in MyList)
{
    MyMethod(item.Id, item.Value);
}

If you really want to use List<T>.ForEach you could write:

MyList.ForEach(item => MyMethod(item.Id, item.Value));

… but I wouldn’t.
