插入使用InsertOneAsync新的文档（.NET 2.0驱动程序）

问题描述

为了.NET API版本：

  MongoClient客户端=新MongoClient（）; 
 VAR服务器= client.GetServer（）; 
变种DB = server.GetDatabase（富）; 
变种集合= db.GetCollection< BsonDocument>（巴）; 
变种文档=新BsonDocument {{_id，1}，{×，2}}; 
 collection.Save（文件）; 
  

它的工作。

当我使用新的.NET驱动程序2.0：

  VAR的客户=新MongoClient（mongodb的：//本地主机：27017）; 
 VAR数据库= client.GetDatabase（富）; 
变种集合= database.GetCollection< BsonDocument>（巴）; 
 
变种文档=新BsonDocument {{_id，1}，{×，2}}; 
等待collection.InsertOneAsync（文件）;

Reading and Writing

I want to ask how to insert a new document using .Net Driver 2.0. Thanks.

[Update 1] I tried to implement :

public class Repository
{
    public static async Task Insert()
    {
        var client = new MongoClient("mongodb://localhost:27017");
        var database = client.GetDatabase("foo");
        var collection = database.GetCollection<BsonDocument>("bar");

        var document = new BsonDocument { { "_id", 1 }, { "x", 2 } };
        await collection.InsertOneAsync(document);
    }
}

static void Main(string[] args)
{            
       Task tsk = Repository.Insert();
       tsk.Wait();
       Console.WriteLine("State: " + tsk.Status);            
}

Result : WaitingForActivation. Nothing changed in database. Please help me!

[Update 2 (Solved)] : add tsk.Wait(); It worked ! Thanks this post : How would I run an async Task method synchronously?

解决方案

Your method should be like

 public async void Insert()
    {
         var client = new MongoClient("mongodb://localhost:27017");
        var database = client.GetDatabase("foo");
        var collection = database.GetCollection<BsonDocument>("bar");

        var document = new BsonDocument { { "_id", 1 }, { "x", 2 } };
        await collection.InsertOneAsync(document);

    }
