检查数组中的特定值

Question

I have 2 arrays which I compare below.

int[] values = { 1, 2, 3, 4, etc };

int[,] limits = { { 1, 2 }, { 2, 5 }, { 2, 6 },etc };

I can compare all the elements of the array quite easily, or specific elements in the array if they are sequential to see if they all fall within the corresponding limits using the following code,

 if (Enumerable.Range(0, values.Length).All(x => values[x] >= limits[x, 0] && values[x] <= limits[x, 1]))
 {
    //Do something            
 };

However, If I wanted to check only specific, non sequentional indecies in the array, eg indexes 0,4,6 & 9 how can I do this ? Thank in advance.

只需将Enumerable.Range替换为要检查的索引的集合即可

new[] {0, 4, 6, 9}.All(x => values[x] >= limits[x, 0] && values[x] <= limits[x, 1])
