Split Json String

How i can split the json string in Unity? I have a string called entry_text, which is passed by a function. When I print it out. It is

"Atmosphere\t7\nGravity\t\nMagnetism\t\nSeismic Activity\t\nSurface\t\nTemperature\t\nWeather\t\nElement 1\t\nElement 2\t\nElement 3\t\n7",

which contains "\t", and "\n". So i want to split the string by "\t" and "\n".

I used the 

 string[] lines = entry_text.Split(new string[] {"\n"}, StringSplitOptions.None);

I also tried 

string[] lines = Regex.Split(entry_text, "\n");

This also does not work:

string[] lines = entry_text.Split(new Char[] {'\n'}, StringSplitOptions.None);

It seems that the split function does not take "\n" as Enter or "\t" as space from Json.

If you have this as your string:

string entry_text = "Atmosphere\t7\nGravity\t\nMagnetism\t\nSeismic Activity\t\nSurface\t\nTemperature\t\nWeather\t\nElement 1\t\nElement 2\t\nElement 3\t\n7";

Remember that the \t and \n in the string are two separate characters: a \ followed by either a t or n.

When you define:

string[] lines = entry_text.Split(new string[] {"\n"}, StringSplitOptions.None);

Your {"\n"} is being translated into a newline character, not two separate characters. For that, you will want to escape the \ character in \n:

string[] lines = entry_text.Split(new string[] {"\\n"}, StringSplitOptions.None);

An alternate way of writing this is to use the @ symbol, which means "take the literal characters in this string, instead of escaping them":

string[] lines = entry_text.Split(new string[] {@"\n"}, StringSplitOptions.None);

You can use multiple delimiters:

string[] lines = entry_text.Split('\t', '\n');

If you want to Split by new-line character you can also try this:

string[] lines = entry_text.Split(new[] { Environment.NewLine }, StringSplitOptions.None);
