c# - 找不到类型或命名空间 AggregateArgs mognodb C#

Question

我在 C# 中进行聚合以获得仅带数组的子集，当实例化 AggregateArgs 属性时，未找到

   public async Task<List<Documents>> GetDocument(string ownerId, string dependentId)
        {

            var args = new AggregateArgs { 

            Pipeline = BsonDocument.Parse("$project: {Dependentsbenefits: {$filter: {input: $Dependentsbenefits, as: depend, cond:{ $eq: [$$depend.dependentId, " + dependentId + "] }}}}");
                  };

        var result = _employee.Aggregate(Pipeline).ToList();
        }
