MongoDB：如何在 C# 中加载带有嵌套数组的集合？

Question

我有一个名为“服务器”的集合，其中包含以下文档。

{
    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# 使用结构从 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>();

但是如果您想要例如 name = west 的所有文档，则可以：

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; }
 }
