&引用；包括「；使用lambda表达式在集合中执行两次

Hy，我想从包含例如“30天”的集合中查找一个项目。 我想先搜索“30”，然后搜索“天”。 我应该如何使用lambda表达式进行此操作？有人能给我举个例子吗

谢谢

试试这个：

var search = "30 days";

var lines = new []
{
    "I will meet you in 30 days.",
    "Payment terms are 7 days",
    "I like 30 as a number",
    "I am happy",
};

var results = 
    lines.Where(line =>search.Split(' ').All(word => line.Contains(word)));

你能分享一些代码来告诉我们你试过什么吗？

var search = "30 days";

var lines = new []
{
    "I will meet you in 30 days.",
    "Payment terms are 7 days",
    "I like 30 as a number",
    "I am happy",
};

var results = 
    lines.Where(line =>search.Split(' ').All(word => line.Contains(word)));
