Cannot implicitly convert string[] to string when splitting

Question

I am new to c# and I don\'t understand why this isn\'t working. I want to split a previously splitted string.

My code is the following:

int i;
string         


        

Answer 1

The result of string.Split() is string[], which you should already see by the correct usage when you assign to string[] temp. But when you are assigning to the elements of string[] temp2, you are trying to store arrays of strings in slots that are meant to only store strings, hence the compiler error. Your code could work with a simple change below.

string[] temp;
string[][] temp2; // array of arrays 

string s = "a-a,b-b,c-c,d-d";
temp = s.Split(',');

temp2 = new string[temp.Length][];

for (int i = 0; i < temp.Length; i++)
    temp2[i] = temp[i].Split('-');
