C# - Cannot implicitly convert type `string[]' to `string'

Question

Trying to take a string, split it by spaces, reverse it, and return the array values.

I have looked at other answers that say you can just return the array like this:

public class Program
    {
        public static string NameShuffle(string str)
        {
                    string[] strArray = str.Split(' ');
                    Array.Reverse( strArray );
                    return strArray;
        }
    }

But for some reason I am getting an error:

Cannot implicitly convert type string[] to string

Answer 1

Your return type on the method is string and it should be string[]

public static string[] NameShuffle(string str)
//             ^HERE^
{
    string[] strArray = str.Split(' ');
    Array.Reverse(strArray);
    return strArray;
}

if you need to convert it back to a string then do something like this

public static string NameShuffle(string str)
{
    string[] strArray = str.Split(' ');
    Array.Reverse(strArray);
    return string.Join(' ', strArray);
}
