Combining multiple conditional expressions in C#

Question

In C#, instead of doing if(index == 7 || index == 8), is there a way to combine them? I\'m thinking of something like if(index == (7, 8)).

Answer 1

You could put the values that you need to compare into an inline array and use a Contains extension method. See this article for starters.

Several snippets demonstrating the concept:

int index = 1;
Console.WriteLine("Example 1: ", new int[] { 1, 2, 4 }.Contains(index));

index = 2;
Console.WriteLine("Example 2: ", new int[] { 0, 5, 3, 4, 236 }.Contains(index));

Output:

Example 1: True
Example 2: False
