Question

我想使用Asp.net核心和MongoDb上传图片;但是，我无法在GridFS课程中找到属性MongoDatabase。我检查了谷歌并没有任何运气。

我需要将GridFS更改为其他内容的方法：

private async Task StoreImage(Computer computer, IFormFile file)
        {
            var imageId = ObjectId.GenerateNewId();
            computer.ImageId = imageId.ToString();
            var filter = Builders<Computer>.Filter.Eq("_id", new ObjectId(computer.Id));
            var update = Builders<Computer>.Update.Set("ImageId", computer.ImageId);
            await db.Computers.UpdateOneAsync(filter, update);
            db.GridFS.Upload(file.ToBson(), file.FileName, new MongoGridFSCreateOptions
            {
                Id = imageId,
                ContentType = file.ContentType
            });
        }

有没有人知道使用ASP.net Core在MongoDB中上传文件的正确方法？

public class CdnDbContext
{
    public IGridFSBucket GridFsBucket { get; set; }
    public CdnDbContext()
    {
        var config = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory())
            .AddJsonFile("appsettings.json")
            .Build();

        var connectionString = config.GetConnectionString("MongoCdn");
        var connection = new MongoUrl(connectionString);
        var settings = MongoClientSettings.FromUrl(connection);
        var client = new MongoClient(settings);
        var database = client.GetDatabase(connection.DatabaseName);
        GridFsBucket = new GridFSBucket(database);
    }
}

使用MongoDb在Asp.NET Core上载文件
