C＃通过字典查找对象的特定条件(C# finding a certain condition of a object via a dictionary)

当前我使用此方法来确定角色是否在线：

public bool OnlineByServer(string username) { foreach (Character c in this.characters.Values) { if (c != null && c.Username.Equals(username)) { return true; } } return false; }

有更快的方法吗？

Current i am using this method to determine if a character is online:

public bool OnlineByServer(string username) { foreach (Character c in this.characters.Values) { if (c != null && c.Username.Equals(username)) { return true; } } return false; }

Is there a faster way to do this?

如果要将字符保留为字典值，则实际上没有更快的方法。 由于未排序，必须进行线性O（n）搜索。

There isn't really a faster way of doing it, if you want to keep the characters as the dictionary Values. Due to being unsorted, a linear O(n) search has to be done.
