如何使用c#2.0驱动程序将数据插入mongodb集合？

Question

1. 我正在使用MongoClient我的c#console应用程序连接到MongoDB

https://github.com/mongodb/mongo-csharp-driver/releases/tag/v2.0.0-rc0

2. 我的代码

     class Program
      {
          static void Main(string[] args)
          {
           const string connectionString = "mongodb://localhost:27017";
   
           // Create a MongoClient object by using the connection string
           var client = new MongoClient(connectionString);
   
           //Use the MongoClient to access the server
           var database = client.GetDatabase("test");
   
           var collection = database.GetCollection<Entity>("entities");
   
           var entity = new Entity { Name = "Tom" };
           collection.InsertOneAsync(entity);
           var id = entity._id;          
       }
   }
   
   public class Entity
   {
       public ObjectId _id { get; set; }
       public string Name { get; set; }
   }
   

3. 成功运行上面的代码后,我无法使用此命令在MongoDB数据库中找到此记录:

   db.entities.find().pretty()
   

我的代码出了什么问题？

Answer 1

这是我创建的用于将数据插入MongoDB的方法,现在工作正常.

static async void DoSomethingAsync()
{
    const string connectionString = "mongodb://localhost:27017";

    // Create a MongoClient object by using the connection string
    var client = new MongoClient(connectionString);

    //Use the MongoClient to access the server
    var database = client.GetDatabase("test");

    //get mongodb collection
    var collection = database.GetCollection<Entity>("entities");
    await collection.InsertOneAsync(new Entity { Name = "Jack" });
}

Answer 2

原因是您需要等待商店才能创建文档.在这种情况下collection.InsertOneAsync(entity); 创建文档之前的执行退出.

Console.ReadKey()或collection.InsertOneAsync(entiry).Wait()或任何其他形式的停止退出几分之一秒都可以解决问题.

对于.net 4.5及更高版本和mongodriver 2x系列,请遵循以下代码

var Client = new MongoClient();
var MongoDB = Client.GetDatabase("shop");
var Collec = MongoDB.GetCollection<BsonDocument>("computers");
var documnt = new BsonDocument
{
    {"Brand","Dell"},
    {"Price","400"},
    {"Ram","8GB"},
    {"HardDisk","1TB"},
    {"Screen","16inch"}
};
Collec.InsertOneAsync(documnt);
Console.ReadLine();
