How can I make an array to insert a bunch of strings?

I'm making a simple obfuscator in c# forms and I'm using this code to insert it:

string a = RandomString(8);
string b = RandomString(8);
string c = RandomString(8);
string d = RandomString(8);
etc...

Code.Text = Code.Text.Insert(0, "set " + a + "=a\n" + "set " + b + "=b\n" + "set " + c + "=c\n" + "set " + d + "=d\n" etc...);

This is the output:

set pbatbpkz=a
set aqtwbqlg=b
set hitsvkvc=c
set imuwqdfy=d
etc...

I need to keep the random strings separate so that I can later insert code to replace characters like "a" with string a.

This obviously does not look efficient or professional. I'm considerably new to c#, so I don't know how I could make something like an array to insert this block of text.

Here's the slightly better code:

Dictionary<char, string> strDict = new Dictionary<char, string>();
for (int i = 0; i < 26; i++)
{
    if (!strDict.ContainsKey((char)(i + 97)))
    {
        strDict.Add((char)(i + 97), RandomString(8));
    }
    else
    {
        strDict[(char)(i + 97)] = RandomString(8);
    }
}

string letterTable = "abcdefghijklmnopqrstuvwxyz";
StringBuilder obfuscationTable = new StringBuilder("");

foreach (char c in letterTable)
{
    obfuscationTable.AppendLine("set " + c + "=" + strDict[c]);
}

Code.Text = Code.Text.Insert(0, obfuscationTable.ToString());

You could use a dictionary that maps these characters to random strings.

Dictionary<string, string> RandomStringDictionary = new Dictionary<string, string>();
RandomStringDictionary.Add("a", RandomString(8));
...
RandomStringDictionary.Add("z", RandomString(8));

Then iterate over your text, and for each character do

RandomStringDictionary[CurrentCharacter]

One way to do this is to use a Dictionary.

   Dictionary<char, string> strDict = new Dictionary<char, string>();
        for (int i = 0; i < 26; i++)
        {
            if(!strDict.ContainsKey((char)(i+97)))
            {
                strDict.Add((char)(i + 97), RandomString());
            }
            else
            {
                strDict[(char)(i + 97)] = RandomString();
            }
        }

This will fill your strDict with random strings that can be accessed with characters from 'a' to 'z' Then you get these strings by:

string strA = strDict['a'] //and so on

I think the structure you are looking for is a Dictionary<char, string>

Naively you would use it like this:

var charLookup = new Dictionary<char, string>{
    {'a', RandomString(8)},
    ...
    {'z', RandomString(8)},
};

Code.Text = Code.Text.Insert(0, "set " + charLookup['a'] + "=a\n" ....

There are many ways to write this in less code. I would recommend using a loop to populate your dictionary, and linq to generate your string.

You should be able to do this in 3 lines of code.

Alternately use a seeded random number generator to do this in one line.
