(我想在LINQ中执行以下操作，但是我不知道如何操作：)

IEnumerable<Item> items = GetItems();

What is the real syntax?

Answer 1

There is no ForEach extension for IEnumerable ;

(没有IEnumerable ForEach扩展;)

only for List<T> .

(仅用于List<T> 。)

So you could do

(所以你可以做)

items.ToList().ForEach(i => i.DoStuff());

Alternatively, write your own ForEach extension method:

(或者，编写您自己的ForEach扩展方法：)

public static void ForEach<T>(this IEnumerable<T> enumeration, Action<T> action)
{
    foreach(T item in enumeration)
    {
        action(item);
    }
}
