How do you conditionally combine filters using the MongoDB C# driver? -


consider following filter:

var builder = builders<product>.filter;  var filter = builder.gte(i => i.price, criteria.minprice) &                             builder.lte(i => i.price, criteria.maxprice); if (0 != criteria.categoryid) //combine following filter previous filter. how??                 var criteriafilter = builder.eq(i => i.categoryid, criteria.categoryid);

how combine criteriafilter , filter?

if (criteria.categoryid != 0) {     var criteriafilter = builder.eq(i => i.categoryid, criteria.categoryid);     filter = filter & criteriafilter; }
