汇总查询转换，从蒙戈DB到C＃

Question

我想下面蒙戈查询（用MongoVUE UI编辑器）转换为C＃

{"$match": {"$and": [{"Users.UserId": {"$all": ["55dbf74d6ada572168fa98b7","55dbf74d6ada572168fa98b8"]}}]}},{ "$unwind": "$Posts"},{ "$sort": {"Posts.CreatedOn": -1}},{ "$skip": 0 },{ "$limit": 11 },{ "$group": {"_id": "$_id", "Posts": {"$push": "$Posts"}} } 

我试着像

var aggregateArgs = new AggregateArgs(); 
      aggregateArgs.Pipeline = new[]  
      { 
       new BsonDocument("$match", new BsonDocument("$and", 
        new BsonArray(new BsonDocument("Users.UserId", new BsonDocument("$all", 
         new BsonArray().Add(paginationData.UserId).Add(paginationData.Id)))))),   
       new BsonDocument("$unwind", "$Posts"), 
       new BsonDocument("$group", new BsonDocument 
        { 
         {"_id", "$_id"},     
         {"Posts", new BsonDocument("$push", "$Posts")}, 
        }), 
       new BsonDocument("$sort", new BsonDocument("Posts.CreatedOn", -1)), 
       new BsonDocument("$skip", paginationData.StartIndex - 1), 
       new BsonDocument("$limit", paginationData.PageSize) 
      }; 

它成功编译，但是当运行它正在返回错误如

.NET类型MongoDB.Bson.BsonElement无法映射到BsonValue

我调试，并找出错误在于以下查询

new BsonDocument("$match", new BsonDocument("$and", 
        new BsonArray(new BsonDocument("Users.UserId", new BsonDocument("$all", 
         new BsonArray().Add(paginationData.UserId).Add(paginationData.Id)))))) 

块，但我无法找出是什么错误。

蒙戈C＃驱动程序是2.0.X版本

任何一个可以帮助我到查询转换为工作查询

编辑我的数据 结构（测试：创建一个临时集合并在下面插入）

请尝试以下查询：

var aggregateArgs = new AggregateArgs(); 
       aggregateArgs.Pipeline = new[]  
       { 
        new BsonDocument("$match", new BsonDocument("$and", 
         new BsonArray().Add(new BsonDocument("Users.UserId", new BsonDocument("$all", 
          new BsonArray().Add(paginationData.UserId).Add(paginationData.Id)))))),   
        new BsonDocument("$unwind", "$Posts"), 
        new BsonDocument("$group", new BsonDocument 
         { 
          {"_id", "$_id"},     
          {"Posts", new BsonDocument("$push", "$Posts")}, 
         }), 
        new BsonDocument("$sort", new BsonDocument("Posts.CreatedOn", -1)), 
        new BsonDocument("$skip", paginationData.StartIndex - 1), 
        new BsonDocument("$limit", paginationData.PageSize) 
       };
