Use Contains() extension method on arrays in C#

问题

There is a Contains() extension method on IEnumerable; In VB I am able to do this:

If New String() {"A", "B"}.Contains("B") Then
    ' ...
End If

What would be the equivalent of this in C#?

回答1:

It is the same idea in C#, using LINQ extension methods:

using System.Linq;
...

if (new string[] {"A", "B"}.Contains("B")) {
    ...
}
