使用三元运算符进行C＃数组初始化？

Question

它们似乎不适用于C＃

string[] directions = 
      IsSomeValueTrue ? string[]{"RIGHT", "LEFT"} : string[]{"UP", "DOWN"};

string[] directions = 
      IsSomeValueTrue ? new string[]{"RIGHT", "LEFT"} : new string[]{"UP", "DOWN"};

我缺少什么？

Answer 1

最短的单行：

var dirs = IsSomeValueTrue ? new[] {"RIGHT", "LEFT"} : new[] {"UP", "DOWN"};

Answer 2

试试这个：

string[] directions = IsSomeValueTrue ? new string[] {"RIGHT", "LEFT"} : new string[]{"UP", "DOWN"};
