推荐答案

类似的东西

var matches = states.Where(state => state.Contains(searchText));

如果大小写也匹配也可以，但是对于不区分大小写的匹配来说效果不佳.为此，您可能想要类似的东西:

That's fine if the case matches as well, but it doesn't work so well for case-insensitive matches. For that, you might want something like:

var matches = states.Where(state => 
      state.IndexOf(searchText, StringComparison.OrdinalIgnoreCase) != -1);

选择适当的确切字符串比较-例如，您可能想使用当前的区域性.

Choose the exact string comparison you want appropriately - you might want to use the current culture, for example.
