有没有办法使用 ASP.NET MVC 将图像文件保存到 Mongo DB？

如何解决有没有办法使用 ASP.NET MVC 将图像文件保存到 Mongo DB？

我一直在尝试创建一个程序，将用户的输入保存到 Mongo DB 中，但是当涉及到用户的文件时，我很挣扎，我已经对如何使用 GridFs 进行了一些研究，我可以使用 GridFS在 C# 中？还是我必须找到其他方法将文件保存到 mongo db？

编辑：这是我的控制器

using System.Collections.Generic;

using MongoDB.Bson;
using MongoDB.Driver;

namespace officialaspnet.Controllers
{
    public class vaccinationController : Controller
    {
        // GET: vaccination
        public ActionResult Index()
        {
            return View();
        }
        public ActionResult Getuserdetail()
        {

            return View();

        }
        [HttpPost]
        public ActionResult Saveuserdetail(string firstname,string lastname,string dob,string studentid,string gender,string email,string phonenumber,string address,string city,string zipcode,string state,HttpPostedFileBase file)
        {
                var client = new MongoClient("mongodb://localhost:27017");
                var database = client.GetDatabase("test1");
                var collec = database.GetCollection<BsonDocument>("test");

                var document = new BsonDocument
            {
                {"Firstname",firstname },{"Lastname",lastname },{"Date of birth",dob },{"Student ID",studentid },{"Gender",gender },{"Email",email },{"Phone number",phonenumber },{"Address",address },{"City",city },{"Zipcode",zipcode },{"State",state },};

                collec.InsertOneAsync(document);
                return Content("Account created");
        }
    }
}

这是我的表格：
