Checking multiple contains on one string

Question

So I have a conditional that currently looks like this...

if (input.Contains(\",\") || input.Contains(\"/\") || input.Contains(@\"\\\") || input.Contains(\".         


        

Answer 1

Try

If (input.IndexOfAny(new char[] { ',', '/', '\\', '.' }) >= 0) {
    ...
}

or

If (input.IndexOfAny(@",/\.".ToCharArray()) >= 0) {
    ...
}

Answer 2

Does this win for shortest?

@".,/\".Any(input.Contains)
