C#mongodb在集合中的文档中插入

下面是doc的结构

{

                                    "subCategory" : [
                                            {

                                                    "subCategory" : [ ]
                                            }
                                    ]
                            },
                            {
                                    "name" : "Jewelry",
                                    "description" : "Jewelry",
                                    "logoPath" : "jewelry.png",
                                    "categoryCode" : "JEWL",
                                    "subCategory" : [
                                            {
                                                    "name" : "Rings",
                                                    "description" : "Rings",
                                                    "logoPath" : "rings.png",
                                                    "categoryCode" : "RINGS",
                                                    "isActive" : 1,
                                                    "subCategory" : [ ]
                                            }
                                    ]
                            }
                    ]
            }
    ]
}

我想在“服装和配饰”子类别中插入以下内容：

{
                    "name" : "XYZ",
                    "description" : "XYZ",
                    "logoPath" : "XYZ.png",
                    "categoryCode" : "XYZ",
                    "isActive" : 1,
                    "subCategory" : [ ]
            }

我们正在使用c#ver 1.8遗留驱动程序连接mongodb

任何人都可以建议如何找到任何级别对象并将其添加进去。

执行以下操作：

var filter = Builders<Category>
             .Filter.Eq(c => c.name, "Apparel & Accessories");

var update = Builders<Category>.Update
        .Push<Category>(c => c.subCategory, mySubCategory);

await collection.FindOneAndUpdateAsync(filter, update);

var过滤器=Builders
.Filter.Eq（c=>c.name，“服装与配饰”）；
var update=Builders.update
.Push（c=>c.subCategory，mySubCategory）；
wait collection.FindOneAndUpdateAsync（筛选、更新）；

我猜您使用的是dll版本2+。我们使用的是1.8遗留dll。你知道怎么做吗？
