在C＃中使用\\字符分割字符串

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?

Answer 1

\\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');

Answer 2

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
}

Answer 3

由于\\n将被解释为新行，并且您无法更改字符串，因此请在Environment.Newline本身上拆分：

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