MongoDb c# driver find item in array by field value

Question

i found the way to check is the value contains in simple array :

var filter = Builders.Filter.AnyEq(x => x.Tags, \"mongodb\");

Answer 1

You need the $elemMatch operator. You could use Builders.Filter.ElemMatch or an Any expression:

Find(x => x.Tags.Any(t => t.Name == "test")).ToListAsync()
