C# 如何在MongoDB&；中更新文档；更改C中除_id之外的所有属性#

我只想更新用户名、CharClass、CharLevel和charcolor

我目前有：

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; }
}

var-client=newmongoclient（DBString）；
var database=client.GetDatabase（“userlist”）；
var collection=database.GetCollection（Convert.ToString（GuildId））；
var filter=Builders.filter.Eq（s=>s.Username，newUserName）；
var UpdatedUserObject=新用户对象
{
UserID=UserID，
Username=newUserName，
CharClass=newCharClass，
CharLevel=newCharLevel，
charcolor=newcharcolor
};
collection.ReplaceOneAsync（筛选器、UpdatedUserObject）；

如果您有任何建议，将不胜感激，我已经添加工作，我只是不能得到更新，谢谢

我最后做了：

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.ReplaceOneAsync(filter, UpdatedUserObject);

修复后，我发现问题在于我传递了错误的用户名，因此它从未匹配&因此没有找到任何要更新的内容，只是我真的很愚蠢，感谢您的帮助

Use collection.UpdateOne（）我得到错误：参数2：当我将其更改为UpdateOne（）时，无法将“TrustMeBot.UserObject”转换为“MongoDB.Driver.UpdateDefinition”TrustMeBot

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);

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; }
}
