Change name and surname in a string

Question

I work with an API that returns the last name to me first after the name and I need the reverse as the name reads ( in my case is a Book Author ), the return I have is ( Ex.: Bragança, Luiz Philippe De Orleans E ) and I need "Luiz Philippe De Orleans E Bragança", I tried to do with Verse but only works with Authors with 2 words.

string.Join(" ", Model.ItemInfo.ByLineInfo.Contributors[0].Name.Split(' ',',').Reverse())

It seems that you want to put the first word at the end of what is returned. So, you can:

public static string NomeAutor(string autor) {
    if(autor.Trim() == "") return "";
    string nomeCompletoRetornado = autor;
    string primeiroNome = nomeCompletoRetornado.Split(new char[] {' ', ','})[0].Trim();
    string resto = nomeCompletoRetornado.Substring(
         primeiroNome.Length + 1,
         nomeCompletoRetornado.Length - primeiroNome.Length - 1).Trim();
    string resultadoFinal = resto + " " + primeiroNome + ".";
    return resultadoFinal;
}

Use:

NomeAutor("Bragança, Luiz Philippe De Orleans E") => "Luiz Philippe De Orleans E Bragança."
NomeAutor("José, Fino de Souza Pereira") => "Fino de Souza Pereira José."

^{See working on .NET Fiddle.}

This will take the full name, get the first name before the ',' or ' ', remove from the original name the size of what was obtained from the first result and briefly concatenate it at the end.
