Question

public class UserObject
{
    public ObjectId _id { get; set; }// Self generated
    public ulong UserID { get; set; } // Self generated
    public string Username { get; set; }
    public string CharClass{ get; set; }
    public int CharLevel { get; set; }
    public int CharColour { get; set; }
}

我想只更新Username，CharClass，CharLevel＆amp; CharColour。

我目前有这个：

var client = new MongoClient(DBString);
var database = client.GetDatabase("UserLists");
var collection = database.GetCollection<UserObject>(Convert.ToString(GuildId));

var filter = Builders<UserObject>.Filter.Eq(s => s.Username, newUserName);

var UpdatedUserObject = new UserObject
{
    UserID = UserId,
    Username = newUserName,
    CharClass = newCharClass,
    CharLevel = newCharLevel,
    CharColour = newCharColour 
};

collection.ReplaceOneAsync(filter, UpdatedUserObject);

如果你有任何建议值得赞赏，我已经得到了添加工作，我似乎无法获得更新，谢谢！

我最终做了：

var client = new MongoClient(DBString);
var database = client.GetDatabase("UserLists");
var collection = database.GetCollection<UserObject>(Convert.ToString(GuildId));

var filter = Builders<UserObject>.Filter.Eq(s => s.Username, newUserName);

var UpdatedUserObject = new UserObject
{
    UserID = UserId,
    Username = newUserName,
    CharClass = newCharClass,
    CharLevel = newCharLevel,
    CharColour = newCharColour 
};

collection.ReplaceOne(filter, UpdatedUserObject);

然后它给了我一个问题，它试图更新_id所以我使用这个堆栈溢出来放置[BsonIgnoreIfDefault]所以它没有尝试更新：

Unable to use BsonIgnoreIfDefault for property of type long

public class UserObject
{
    [BsonIgnoreIfDefault]
    public ObjectId _id { get; set; }// Self generated
    public ulong UserID { get; set; } // Self generated
    public string Username { get; set; }
    public string CharClass{ get; set; }
    public int CharLevel { get; set; }
    public int CharColour { get; set; }
}

在修复此问题后，我发现问题是我通过了错误的用户名，因此它从未匹配过＆amp;因此没有找到任何更新，只是我真的很蠢，谢谢你的帮助
