如何在c#中替换列表中的多个值？

List<string> myList = new List<string>{"apple", "banana", "orange", "grape"};

for (int i = 0; i < myList.Count; i++)
{
    if (myList[i] == "banana" || myList[i] == "orange")
    {
        myList[i] = "fruit";
    }
}

foreach (string item in myList)
{
    Console.WriteLine(item);
}

apple
fruit
fruit
grape
