I need to replace either just the word in a json message in C#

i.e.

"month" = "july"

I need to replace it with

string p = "june"

"month"= p and have the "" appear however im not allowed to do " + p + "

so either i would have to directly replace the word june and not touch the "

OR

i need to find a way to store the " in p such as

string p = "/"june/""; //however that didnt work

***the first method is the perferred way however im not sure how to do it i was thinking regex but im not sure what that would look like
