c# - Creating a string that uses key value pairs and extract the values from it by key -

i have need store key value pairs in string. cannot store them in other type because function passing these values takes param called additionaldata , of type string.

string data = "firstname: mike, lastname: jones, userid: 101" 

i need able retrieve each value based on key.

i , string.join create array when retrieving prefer not because want use key value:

string data = string.format("{0}|{1}|{2} ", "mike", "jones", 101) 

user user = new user {     firstname = "mike",     lastname = "jones",     userid = 101 }; string userjson = jsonconvert.serializeobject(user); 

you can create user object , parse json using https://www.nuget.org/packages/newtonsoft.json/

and later when want deserialize it, can use code below:

user user = jsonconvert.deserializeobject<user>(userjson); 

hope helps.
