c# - 比较 LINQ 方法语法中的 2 个数字列表

Question

我有 2 个数字列表。

public int[] numbersA = { 0, 2, 4 };
public int[] numbersB = { 1, 3, 5 }; 

我需要如下输出

预期结果

0 is less than 1
0 is less than 3
0 is less than 5

2 is less than 3
2 is less than 5

4 is less than 5

如何通过LINQ方法语法实现？

Answer 1

使用方法语法:

var result = numbersA.SelectMany(c => numbersB, (c, o) => new { c, o })
                     .Where(d => d.c < d.o)
                     .Select(v=>  v.c + "is less than"+ v.o);
