Grab part of a string

Question

How do I get just up to the , of the following string:

Ninguem ninguem, todos

Expected result:

Ninguem ninguem

Answer 1

I leave here another alternative, and with the execution times of 10,000,000 times.

string texto = "Ninguem ninguem, todos";  

string resultado = texto.Substring(0, texto.IndexOf(',')); // 0.383s

string resultado = texto.Split(',')[0]; // 1.400s

string resultado = new string(texto.TakeWhile(c => c != ',').ToArray()); //5.204s

string resultado = string.Concat(texto.TakeWhile(c => c != ',')); // 6.746s

string resultado = Regex.Split(texto, ",")[0]; // 8.595s

Answer 2

Try wearing something like this,

string data = "Ninguem ninguem, todos";
string[] words = data.Split(",");

This could be solved with regex.

Answer 3

You also have the option to use LastIndexOf with the Substring. Where do you indicate startIndex and the size you want to take from string

string texto = "Ninguem ninguem, todos";        
string textoCortado = texto.Substring(0, texto.LastIndexOf(","));
Console.WriteLine(textoCortado);

Answer 4

I did so with regex:

string campo = campo_texto.Text;

string[] nome = Regex.Split(campo, ",");
