c# - list.ToString 没有显示正确的输出

Question

我正在尝试将列表中的项目转换为字符串。但每次我转换它或显示它时，它都显示为“TwitchIrcChar.user”。如果有人可以帮助解决这个问题，那将非常有帮助。对不起，如果菜鸟问题，但我是列表的新手。我试过使用 convert.ToString 和 userlist.tostring。两者都给出了相同的输出

您可以像其他人建议的那样覆盖 ToString，或者如果 UserName 是您所希望的，您就可以这样做。

Console.WriteLine(userList[i].UserName.ToString());

或

Console.WriteLine(userList[i].UserName);

因为它已经是一个字符串
