Mongo在C#中插入_v字段

using MongoDB.Bson;
using MongoDB.Driver;

public class MyClass
{
    private IMongoCollection<BsonDocument> collection;

    public MyClass()
    {
        // 连接MongoDB数据库
        var client = new MongoClient("mongodb://localhost:27017");
        var database = client.GetDatabase("mydb");
        
        // 获取集合
        collection = database.GetCollection<BsonDocument>("mycollection");
    }

    public void InsertData()
    {
        // 创建要插入的文档
        var document = new BsonDocument
        {
            { "_v", "插入的值" },
            { "field1", "value1" },
            { "field2", "value2" }
        };

        // 插入文档
        collection.InsertOne(document);
    }
}
