asp.net mvc LINQ，如何比较其他值范围内的值范围

Question

比较一个范围内的值，如果第一个范围内的任何值在第二个范围内可用，则结果应为假，如果第一个范围在第二个范围内完全不可用，则结果为真。

range 1 = 1 to 100
range 2 = 1 to 200
range 3 = 180 to 300;
range 4 = 301 to 400;

case 1 -> range1 / range2 = false //

case 2 -> range3 / range2 = false //

case 3 -> range4 / range 2 = true

如何用 mvc linq 实现这个

提前致谢。

Answer 1

下面的方法呢：

var firstRange = Enumerable.Range(1, 100);
var secondRange = Enumerable.Range(1, 200);
var thirdRange = Enumerable.Range(180, 300);
var fourthRange = Enumerable.Range(301, 400);

var case1 = !firstRange.Any(element => secondRange.Contains(element));
var case2 = !thirdRange.Any(element => secondRange.Contains(element));
var case3 = !fourthRange.Any(element => secondRange.Contains(element));

Console.WriteLine(case1);
Console.WriteLine(case2);
Console.WriteLine(case3);

Answer 2

你可以这样试试，here是link现场演示。

using System;
using System.Collections.Generic;
using System.Linq;

public class Program
{
    public static void Main()
    {
        var firstRange = Enumerable.Range(1, 100);
        var secondRange = Enumerable.Range(1, 200);
        var thirdRange = Enumerable.Range(180, 300);
        var fourthRange = Enumerable.Range(301, 400);

        Console.WriteLine(!IsContainInRange(firstRange, secondRange));      
        Console.WriteLine(!IsContainInRange(thirdRange, secondRange));
        Console.WriteLine(!IsContainInRange(fourthRange, secondRange));
    }

    private static bool IsContainInRange(IEnumerable<int> range1, IEnumerable<int> range2)
    {
        return (from r1 in range1
                 join r2 in range2 on r1 equals r2 
                 select r1).Any();
    }
}
