How can I loop through a List and grab each item?
I want the output to look like this:
Console.WriteLine("amount is {0}, and type is {1}", myMoney.amount, myMoney.type);
Here is my code:
static void Main(string[] args)
{
List<Money> myMoney = new List<Money>
{
new Money{amount = 10, type = "US"},
new Money{amount = 20, type = "US"}
};
}
class Money
{
public int amount { get; set; }
public string type { get; set; }
}
This question is related to
c#
for-loop
collections
Just for completeness, there is also the LINQ/Lambda way:
myMoney.ForEach((theMoney) => Console.WriteLine("amount is {0}, and type is {1}", theMoney.amount, theMoney.type));
The low level iterator
manipulate code:
List<Money> myMoney = new List<Money>
{
new Money{amount = 10, type = "US"},
new Money{amount = 20, type = "US"}
};
using (var enumerator = myMoney.GetEnumerator())
{
while (enumerator.MoveNext())
{
var element = enumerator.Current;
Console.WriteLine(element.amount);
}
}
This is how I would write using more functional way
. Here is the code:
new List<Money>()
{
new Money() { Amount = 10, Type = "US"},
new Money() { Amount = 20, Type = "US"}
}
.ForEach(money =>
{
Console.WriteLine($"amount is {money.Amount}, and type is {money.Type}");
});
Just like any other collection. With the addition of the List<T>.ForEach
method.
foreach (var item in myMoney)
Console.WriteLine("amount is {0}, and type is {1}", item.amount, item.type);
for (int i = 0; i < myMoney.Count; i++)
Console.WriteLine("amount is {0}, and type is {1}", myMoney[i].amount, myMoney[i].type);
myMoney.ForEach(item => Console.WriteLine("amount is {0}, and type is {1}", item.amount, item.type));
