MongoDB的连接使用Web API [英] Connect MongoDB with Web API

问题描述

我想用的MongoDB API网站在Visual Studio 2013年所有我想要做的就是创建一个C＃一个简单的数据库连接。我所有的code是在Values​​Controllers.cs文件。我创建了一个简单的模型类 -

I am trying to connect MongoDB with Web API in Visual Studio 2013. All I want to do is create a simple database with C#. All of my code is in ValuesControllers.cs file. I created a simple Model class -

public class Book
{
    [BsonId]
    public int Id { get; set; }
    public string Title { get; set; } 
}

和修改的Get方法

public IEnumerable<Book> Get()
{
     MongoClient client = new MongoClient();
     var server = client.GetServer();
     var db = server.GetDatabase("BookStore");
     var collection = db.GetCollection<Book>("Book");
     Book[] books = new Book[] 
     { 
            new Book {Id = 1, Title="Book Name 1" },
            new Book {Id = 2, Title="Book Name 2" },
            new Book {Id = 3, Title="Book Name 3" },
            new Book {Id = 4, Title="Book Name 4" }

     };
     collection.Save(books);
     return books;
}

它返回值，但不创建数据库。我在控制台应用程序尝试这样做，它的作品。
我想打一个简单的例子来连接MongoDB中。

It returns values but doesn't create database. I tried this in console application and it works. I want to make a simple example to connect MongoDB.

推荐答案

以下code应该工作。请确保您有在后台运行蒙戈数据库。

The following code should work. Make sure you have the mongo database running in the background.

我修改你的code如下：

I've modified your code as follows

1. 创建MongoClient对象时，我添加了蒙戈连接URL
   所以它会连接到本地蒙戈分贝。


2. 在保存图书到
   DB，而不是试图数组直接保存到数据库中，code
   现在遍历每个项目并单独保存。

下面是code

public IEnumerable<Book> Get()
{     
    var client = new MongoClient("mongodb://localhost:27017");
    var server = client.GetServer();
    var db = server.GetDatabase("BookStore");
    var collection = db.GetCollection<Book>("Book");
    Book[] books =
    {
         new Book { Id = 1, Title = "Book Name 1" }, 
         new Book { Id = 2, Title = "Book Name 2" },
         new Book { Id = 3, Title = "Book Name 3" }, 
         new Book { Id = 4, Title = "Book Name 4" }
    };
    foreach (var book in books)
    {
        collection.Save(book);
    }
    return books;
}
