Converting from integer value to array not returning the correct, original values

I have a C# application where I am saving off my array into an integer value, which is working.

here is my array: int[] myArray = { 0, 1, 3, 15 };

However, when I try to convert myArray to see what values it has it returns the following {1, 3, 1, 5} as you can see it doesn’t get the 0, and it separates the 15 into {1, 5}.

Here is my approach:

double[] array = { 0, 1, 3, 15 };

var result = string.Concat(array);


int resultNumber = int.Parse(result); // returns 1315

int[] resultToArray = resultNumber.ToString().Select(o => Convert.ToInt32(o) - 48).ToArray();

What am I missing from my resultToArray?

>Solution :

int[] myArray = { 0, 1, 3, 15 };
string concatenated = string.Join(",", myArray);
Console.WriteLine("Concatenated string: " + concatenated);
int[] resultToArray = concatenated.Split(',').Select(int.Parse).ToArray();
Console.WriteLine("Result array: " + string.Join(", ", resultToArray));

i guess no need to explain much in above code,it’s self explanatory. i just used string.Join(",", myArray) to create a string with each integer separated by a comma and then split it back into an array using Split(‘,’) and parsed each element back to an integer using Select(int.Parse)

this would work fine imo, let me know!
