C# Declare multiple dynamically named variables

Question

I'm not sure of the wording of what I'm looking for so I apologize if this has been answered since I'm new to C#.

What I'm trying to do is create multiple dynamically-named Lists based off of "i".

A code snippet would like this:

List<string> infoForUserSessions = new List<string>();

// Code that adds data to infoForUserSessions

for (int i = 0; i < infoForUserSessions.Count; i++){

// I want to initialize multiple List variables based off of how many users were found in my "infoForUserSessions" List.

  List<string> user[i];
}

I was hoping it would create new Lists named:

user1

user2

user3

etc.

Update Sorry all for being so confusing. You guys swarmed with answers! Let me be more specific. I'm practicing string output from a Console application such as using "PsExec \localhost qwinsta". The output would look like this:

 SESSIONNAME       USERNAME                 ID  STATE   TYPE        DEVICE
 services                                    0  Disc
>console           mariob                    1  Active
 rdp-tcp                                 65536  Listen

Each line is stored in the List "infoForUserSessions" so the data looks like:

infoForUserSessions[0] = services                                    0  Disc
infoForUserSessions[1] = >console           mariob                    1  Active
infoForUserSessions[2] = rdp-tcp                                 65536  Listen

I then have code to pick out the important text out of each array index:

string[] tempStringArray;
List<string> allUsersAndIDs = new List<string>();
char[] delimiters = new char[] { ' ' };

foreach (string line in infoForUserSessions)
{
    tempStringArray = line.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);

    for (int i = 0; i < tempStringArray.Length; i++)
    {
      // This is where I was thinking of some logic to create a new array for each user so I could store the separate parts of a string into this new array

      // Something like (which would be from the Lists above in my original message--this is based off of how many users were stored in the original infoForUserSessions List:
      // user1.Add(i);
    }
}

I'm still working out the logic but I figured I wanted the output to be something dynamic based off of two factors:

1. How many "users" (strings) were stored in the List infoForUserSessions
2. Individual user arrays/Lists that have their own index values of:

.

user1[0] = "services";
user1[1] = "0";
user1[2] = "Disc";

user2[0] = ">console";
user2[1] = "mariob";
user2[2] = "1";
user2[2] = "Active";

Answer 1

Don't try to use dynamically named variables. That's simply not how variables work in C#.

Use an array of lists:

List<string>[] user = new List<string>[infoForUserSessions.Count];

for (int i = 0; i < infoForUserSessions.Count; i++) {
  user[i] = new List<string>();
}

If the number of sessions can change, you would use a List<List<string>> instead, so that you can add lists to it when you add items to the infoForUserSessions list.

Answer 2

You can use Dictionary<String, List<string>>

Dictionary associate a key to a value, like an physical Dictionary book.

Dictionary<String, List<string>> myDict = new Dictionary<String, List<string>>();

for (int i = 0; i < infoForUserSessions.Count; ++i){
    myDict.add("user" + i, new List<string>());
}

Here is an exemple how to use Dictionary :

Dictionary<String, String> myDict = new Dictionary<String, String>();
//Line below will add both KEY and a VALUE to the dictionary, BOTH are linked one to eachother
myDict.add("apple", "Apple is a brand");

//This above line return "Apple is a brand"
myDict["apple"];
