Delegate isn't working

I come across a change in a program which my current infastructure couldn't handle and was become too long: I had to stop using such absolute code and move towards Object Orientated.

Repetition issue:

List<string[]> logos = new List<string[]>();
string[] tempLogo = new string[2];
tempLogo[0] = "FRONT EMB";
tempLogo[1] = front_emb;
logos.Add(tempLogo);
tempLogo[0] = "back EMB";
tempLogo[1] = back_emb;
logos.Add(tempLogo);

Became:

delegate string addLogo(string x); // Namespace area

public static void IntergrateLogo(string toAdd, string name) // Inside Class
{
    string[] tempLogo = new string[2];
    tempLogo[0] = name;
    tempLogo[1] = toAdd;
    logos.Add(tempLogo);
}

// Main method
addLogo adl = new addLogo(IntegrateLogo);
List<string[]> logos = new List<string[]>();
adl(front_emb,"FRONT EMB");
adl(back_emb,"BACK EMB");

Issue:

1. The name 'logos' does not exist in the current context

2. No overload for 'IntergrateLogo' matches delegate 'addLogo'

3. Embedded statement cannot be a declaration or labeled statement

Question:

From my, very low, knowledge on delegates, they should 'mimic' the main method environment; therefore, my List - logos, should be able to be seen and used inside the IntergrateLogo method.

Well, that understanding went out the window when I couldn't get this working.

I am not asking for a fix here, I just want a better understanding with delegates because everywhere I search, it says that it allows the context environment scope to be accessed within a method but clearly that is not working here.

Is there a way that logos can be seen within the IntergrateLogo method by using a delegate?
