How to check if something equals any of a list of values in C#

Question

What is the OR operator in an IF statement

I asked this question way back when, and when I got the (very helpful) answer, I thought you should be able to say if (title == "User greeting" || "User name") {do stuff}. Now if it isn't obvious why that won't work, please refer to the other question and its accepted answer.

I am wondering, however, if there is a way to give an arbitrary list of strings to check if something equals any of them. Something like if(Array.OR(title, { "User greeting", "User name" })) continue; Is there such a thing or am I shooting in the dark? It seems like it'd be rather simple to implement.

Answer 1

You could try the Contains operator:

String[] array = {"One", "Two", "Three"};
if (array.Contains("One"))
{
     //Do stuff       
}

Answer 2

CorrugatedAir's example is pretty good, however you can include it inline if needed.

if (new string[] { "test1", "test2", "test3" }.Contains("test1")) Console.WriteLine("it works");

And it does work: http://ideone.com/QzbvKV (Thanks Soner)

So my code would look like: if (new string[] { "User greeting", "User name" }.Contains(title)) Console.WriteLine("title contained");
