Split a string with the \ character in C#

Question

I am trying to split this string in C#.

"FiO2 at 0.40\n36°C-37°C\nFlow at 5 L/min"

I have tried using this code:

string[] splitVapo = value.Split('\u005c');

and this

string[] splitVapo = value.Split('\\');

But it does not work. Any suggestions?

\n is new line. there is no \ character there. \ is used for escaping. so \\ in string means there is \. — M.kazem Akhgary

var value = "FiO2 at 0.40\n36°C-37°C\nFlow at 5 L/min"; string[] splitVapo = value.Split('\n'); works just fine; splitVapo.Lenght is 3 — ASh

\n is a single char literal though it looks like two characters in the source code

\n is a New line escape sequence (msdn)

so

var value = "FiO2 at 0.40\n36°C-37°C\nFlow at 5 L/min"; 
string[] splitVapo = value.Split('\n');

works just fine and splitVapo.Lenght is 3

it would have worked also if you had provided correct hex code for \n

string[] splitVapo = value.Split('\u000A');

You want to split everytime you see '\n', correct? You can try this:

string str = "FiO2 at 0.40\n36°C-37°C\nFlow at 5 L/min";            
string[] result = str.Split('\n');
for (int i = 0; i < result.Length; ++i) {
    //do something with result[i] if needed
}

Why a new char array of \n when Split already takes a character and you only use one?

@Bauss You are right. Sorry, that was simply my typing habit.

Since \n is going to be interpreted as a new line and you cannot change the string, split on Environment.Newline itself:

string[] splitVapo = value.Split(Environment.NewLine.ToCharArray());

Split already takes a char, so converting it to an array of chars is redundant.
