lambda - 使用 lambda 表达式在集合中“包含”两次

Question

嗨，我想从包含例如“30 天”的集合中找到一个项目。我想先搜索“30”，然后再搜索“天”。我应该如何使用 lambda 表达式来做到这一点？有人可以给我一个例子吗？

谢谢

Answer 1

string search = "30 days";

var result = MyEnumerable.Where(x=>search.Split(' ').Contains(x.fieldToSearch))

Answer 2

尝试这个：

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)));
