c# - undefined number of Or-operation on List -
i have list n-entries. list<myclass> result and have list n-filter options list<string> filters what want return result list filtered other list. for and-operation easy this: foreach (var filter in filters) { results = results.where(x => x.result == filter); } but how code or-operation? you can use where in combination any in case: results = results.where(x => filters.any(f => f == x.result)); https://msdn.microsoft.com/library/bb534972(v=vs.110).aspx others ways: //contains, see daxaholic's post results = results.where(x => filters.contains(x.result)); https://msdn.microsoft.com/library/bhkz42b3(v=vs.110).aspx //list extension method 'exists' results = results.where(x => filters.exists(f => f == x.result)); https://msdn.microsoft.com/library/bfed8bca(v=vs.110).aspx
