C#

Hi all;
Imagine I have defined 3 variables as follow:
String x1="Hello";
String x27="Hi";
String x99="Hey";

Then later in the program code I want to access the content of them by making their name. 

Int i=27;

/*	In this section I want to concatenate the variable "i" to the string "x" and then show the content of it or even assign a new value to it.
For example:
*/
                 Messagebox.show("x" + i.tosting()); 

/*		The output will be: "x27". But I want to show the content of x27 variable, that is the word "Hi". 
Don’t forget that I don’t want to use Array or Dictionary or List and so on. My goal is: to make a variable name and access to its content or assign it a new value like this:
*/
"x" + i.tosting() = "New";        // x27 = "New";
 
What's the correct code in C#? Any idea?
Thank you in advance.
