Question

I have many complex queries that I sometimes wish to check directly against Mongo for debugging \\ explaining() purposes. With the newer 2.0+ c# driver, i\'m not sure how t

Answer 1

If you're using the latest version of the driver, which is 2.0.1 you can easily put that filter in a Find operation, get back an IFindFluent and print its ToString:

var filter = Builders.Filter.Where(e => ids.Contains(e.Id) && e.Deleted != true);
var findFluent = collection.Find(filter);
Console.WriteLine(findFluent);

For example for me this prints:

find({ "_id" : { "$in" : [1, 2, 3] }, "Deleted" : { "$ne" : true } })
