Joining multiple where clauses in LINQ as OR instead of AND

Question

Is there anyway to join LINQ where clauses as OR ?

var ints = new [] { 1, 3, 5, 7 };

var query = from i in ints select i;

query = query.Where (q => q == 3);

query = query..Where (q => q == 7);

What I want is the ability to dynamically add where clauses but make them use OR instead of AND

You can using Union method:

var ints = new [] { 1, 3, 5, 7 };
var query = ints.Where(q => q == 3);
query = query.Union(ints.Where(q => q == 7));
