.net - C# mongo queries with json strings -

It looks so basic that I'm convinced that I'm ignoring an orbit or a method, but For me, I can not find it

I've got a Jason string like this:

  {SendId: 4, "Events.Code": {$ all: [2], $ nin: [3 ]}}   
 I can run this in a mongo shell against a  find ()  or  count ()  and what I find I am getting it. What is the easiest way to deal with this in C #?    
    BsonDocument  has a good parsing method, but it is  IMongoQuery   
  does not implement   BsonDocument  code>, and it implements  IMongoQuery , but in it It does not have its own parsing method, and I take a  BsonDocument  [] from  QueryDocument  to  BsonDocument   
 the aggregation framework, but Sometimes I just want to do a simple search or calculation work  
 Some of these questions are big and Gross, and I do not want to make them a line one line with  query  builder class   
, if the database works with json documents, and I get this stuff Can not run in the shell, is there any way to run it with the driver?   
 
 
 It's ugly, but you can do this by doing this to   BsonDocument  and then wrapping in  QueryDocument   
  BsonDocument Query = MongoDB.Bson.Serialization.BsonSerializer. . Direct & lt; BsonDocument & gt; ("{SendId: 4, 'Events.Code': {$ all: [2], $ nin: [3]}}"); QueryDocument queryDoc = new query document (query); Var Results = Archive. FDAS & lt; Typeofferscent estimated & gt; (QueryDoc); // Simply use the search   
 If there is anything that you plan to do often, you can always wrap it in a method, or a  like the following JSQueryDocument can create class:  
  public class JSQueryDocument: QueryDocument {public JSQueryDocument (string query): base (MongoDB.Bson.Serialization.BsonSerializer.Deserialize.Deserialize & lt; BsonDocument & gt ; {Query}) {// Perhaps it is better to do this as a method instead of constructor / / debugging it queries Programming can not be formatted correctly}} /// ... var results = collection. Find (New JSQueryDocument ("{SendId: 4, 'Events.Code': {$ All: [2], $ nin: [3]}}"));
