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(\".

How about this?

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

    }
