Question

C#，把几个数组的内容按顺序放到另一个数组中

比如，有三个数组string [] a = {1,2}; string [] b = {3,4,5}; string [] c = {6,7};然后，我想把这三个数组的的内容按顺序放到另一个数组d中，最终达到 string [] d = {1，2，3，4，5，6，7}；的效果

Answer 1

static void Main(){
            Int32[] ia = { 1, 2, 3 };
            Int32[] ia_two = { 4, 5, 6 };
            Int32[] ia_three = new Int32[ia.Length+ia_two.Length];

            ia.CopyTo(ia_three, 0);
            ia_two.CopyTo(ia_three,ia.Length);
}
