如何遍历 List 并抓取每个项目？
I want the output to look like this:
我希望输出看起来像这样：
Console.WriteLine("amount is {0}, and type is {1}", myMoney.amount, myMoney.type);
Here is my code:
这是我的代码：
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; }
}

foreach:
foreach：
foreach (var money in myMoney) {
Console.WriteLine("Amount is {0} and type is {1}", money.amount, money.type);
}
Alternatively, because it is a List<T>.. which implements an indexer method [], you can use a normal forloop as well.. although its less readble (IMO):
或者，因为它是一个List<T>实现索引器方法的.. []，您也可以使用普通for循环.. 尽管它的可读性较低（IMO）：
for (var i = 0; i < myMoney.Count; i++) {
Console.WriteLine("Amount is {0} and type is {1}", myMoney[i].amount, myMoney[i].type);
}

Just like any other collection. With the addition of the List<T>.ForEachmethod.
就像任何其他收藏一样。随着List<T>.ForEach方法的加入。
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));

Just for completeness, there is also the LINQ/Lambda way:
为了完整起见，还有 LINQ/Lambda 方式：
myMoney.ForEach((theMoney) => Console.WriteLine("amount is {0}, and type is {1}", theMoney.amount, theMoney.type));

This is how I would write using more functional way. Here is the code:
这就是我使用 more 编写的方式functional way。这是代码：
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}");
});
