public const str[]=new string[3]{"ab","bc","cd"};

public static readonly string[] str = new string[3] { "ab", "bc", "cd" };

------解决方案--------------------
探讨

C# code
public static readonly string[] str = new string[3] { "ab", "bc", "cd" };


------解决方案--------------------
觉得不方便你就用List<string>算了，功能比定义string[] 数组强
