Question

There is in operator in SQL

SELECT * FROM MyTable WHERE id IN (1, 2, 3, 4, 5)

Is there similar sintax in C#, I mean

if(variable in (1, 2, 3, 4, 5)){
}

Answer 1

There isn’t a good one but you can write it yourself as an extension method:

public static class Extensions
{
  public static bool In<T>(this T value, params T[] items)
  {
      return items.Contains(value);
  }
}

if (v.In(1,2,3,5)) { /* do stuff */ }

I haven’t tested it, but it should be good.

UPDATE: As suggested by OP, I’ve corrected a few typos.
