MongoDB的更新嵌套數組對象，其中有數組文件

Question

這裏的比賽是我的MongoDB文檔

{ 
    "_id":20, 
    "GroupId":"45", 
    "Name":"Some Name", 
    "NestedArray":[ 
     { 
     "Id":3, 
     "Name":"NesName", 
     "IsDeleted":false 
     } 
    ] 
} 

我需要寫一個更新語句一樣（在SQL解釋）

update MyCollections.NestedArray set MyCollections.NestedArray[x].IsDeleted = true where MyCollections.NestedArray[x].Id = 3 

這裏我用MongoDB 3.2我怎麼能拿出一個MongoDB的C＃驅動程序查詢試圖

var groupFilter = Builders<MyType>.Filter.Eq(x => x.Id, 45); 
var nestedArayDocUpdate = Builders<MyType>.Update.Set(x => x.NestedArray[0].IsDeleted, true); 
mongoDbRepository.UpdateMany(groupFilter, nestedArayDocUpdate, 
       new UpdateOptions {IsUpsert = false, BypassDocumentValidation = false}); 

？

Answer 1

這就是我最終做到的。

var updateBuilder = Builders<Type>.Update. 
          .Set(x => x.NestedArray[-1].IsActive, false) 
          .Set(x => x.NestedArray[-1].IsDeleted, true); 

mongoDbRepository.UpdateOne(Builders<Type>.Filter.Where( 
    x => x.NestedArray.Any(c => c.Id == categoryId)), updateBuilder);
