c# - 通过部分键c#字典获取值

Question

我有这本字典。

private Dictionary<string[], ICommand> commandsWithAttributes = new Dictionary<string[], ICommand>();

我需要通过部分键在 commandsWithAttributes 中找到元素。我的意思是:

“-?” - 是我用来查找项目的键。

({"-t","--thread"},ICommand)

({"-?","--help"},ICommand) <- 这就是我需要找到的。

请不要这样做。字典针对一键到一值搜索进行了优化。

我建议对单个值使用多个键如下:

private Dictionary<string, ICommand> commandsWithAttributes = new Dictionary<string, ICommand>();

var command1 = new Command(); //Whatever

commandsWithAttributes.Add("-t", command1);
commandsWithAttributes.Add("--thread", command1);

var command2 = new Command(); //Whatever

commandsWithAttributes.Add("-?", command2);
commandsWithAttributes.Add("--help", command2);
