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

我要插入到 「服裝&附件」 有下列內容的子類別：

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

我們使用的是C＃1.8版本舊的驅動程序連接的MongoDB。

任何人都可以請建議如何找到任何級別的對象，並添加它。

Answer 1

做這樣的事情：

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);
