What results can you expect?

Once the analysis/snapshot generation has completed, you can view the results in the normal manner (for example via CAST Enlighten). Some examples are shown below.

Database and Collection Creation


static void InsertOneInMongoDB()
        {
        
            MongoClient client = new MongoClient("mongodb://127.0.0.1:27017");
          
            IMongoDatabase db = client.GetDatabase("TestDb1");
     
            IMongoCollection<Person> persons = db.GetCollection<Person>("Persons");
            IMongoCollection<Dog> dogs = db.GetCollection<Dog>("Dogs");
}

Insert Operation


{
            MongoClient client = new MongoClient("mongodb://127.0.0.1:27017");
            IMongoDatabase db = client.GetDatabase("TestDb1");
            IMongoCollection<BsonDocument> dogs = db.GetCollection<BsonDocument>("Dogs");

            string json = "{Name:'大黄',Age:10,Weight:50}";
            BsonDocument d1 = BsonDocument.Parse(json);//解析Json数据
            dogs.InsertOne(d1);

}

Delete Operation


 public void DeleteAllPurchases()
        {
            MyShoppingCollection.DeleteMany(FilterDefinition<PurchaseBson>.Empty, null);
        }

Select Operation


public PurchaseBson[] FindPurchases()
        {
            var purchases = MyShoppingCollection.Find(FilterDefinition<PurchaseBson>.Empty, null).ToList();
            return purchases.ToArray();
        }

Update Operation


 public async Task<IActionResult> Update()
        {
            var query = from k in (from a in _context.Books.AsQueryable()
                                    where a.Title == "Test Book 2"
                                    from b in a.Posts
                                    select b)
                         where k.Title == "Second One"
                         select k;
            var result = await query.FirstOrDefaultAsync();
            result.ReadCount = 5;

            _context.Books
                .FindOneAndUpdate(x => x.Title == "Test Book 2" && x.Posts.Any(p => p.Title == "Second One"),
                                    Builders<Book>.Update.Set(x => x.Posts[-1], result));

            return Redirect("/");
        }
