MongoDB：如何在C＃中使用嵌套数组加载集合？

Question

我有一个名为“服务器”的集合，包含以下文档。

{
    name: "West",
    ip: "123.123.123.123",
    channels:
    [
        {
            name: "English",
            port: "1234",
            status: "0"
        },
        {
            name: "Spanish",
            port: "1235",
            status: "0"
        },
        {
            name: "German",
            port: "1236",
            status: "0"
        }
    ]
},
{
    name: "East",
    ip: "122.122.122.122",
    channels:
    [
        {
            name: "English",
            port: "1234",
            status: "0"
        },
        {
            name: "French",
            port: "1235",
            status: "0"
        }
    ]
}

我如何使用C＃using结构从MongoDB中选择它？

Answer 1

如果您想要所有项目，您可以使用以下代码：

var server = MongoServer.Create("mongodb://localhost:27020");
var database = server.GetDatabase("someDb");

var servers = database.GetCollection<ServerItem>("servers");
servers.FindAllAs<ServerItem>();

但是，如果您想要所有名称为west的文档，那么您可以：

collection.FindAs<ServerItem>(Query.EQ("name","west"));

ServerItem：

 public class ServerItem
 {
   public string name { get; set; }

   public string ip { get; set; }

   public List<Channel> channels { get; set; }
 } 

 public class Channel
 {
   public string name { get; set; }

   public int port { get; set; }

   public int status { get; set; }
 }
