c# Convert string to Variable

I am working in C# converting MS Batch files to WindowsForms.

I have need to read in a list of key=value lines from text files and convert the key to a variable.

Example text
MailClass=Std
Selectivity=MailNoErrors
MailForeigns=No
ImbType=FS
Postnet=No

I would like to set these as variables to be passed between methods and forms as needed. 

string MailClass = "Std";
string Selectivity = "MailNoErrors";
string MailForeign s= "No";
string ImbType = "FS";
string Postnet = "No";

I am thinking of loading them into a List[] array.

Where I am getting is how do I make them actual variables?

using a Dictionary would be more appropriate to the task at hand.

An example would be something like this: 

Dictionary<string, string> myDictionary = new Dictionary<string, string>(); // make this global
var file = File.ReadAllLines(path);
List<string> TempList = new List<string>(file);
TempList.ForEach((line) =>
{
     string[] TempArray = line.Split('=');
     myDictionary.Add(TempArray[0], TempArray[1]);
});

After you've done that then you can just access you key/value pairs from the Dictionary.

I would take it one step forward and create a class:

public class MyVars {
    public string MailClass {get;set;}
    public string Selectivity {get;set;}
    public string MailForeigns {get;set;}
    public string ImbType {get;set;}
    public string Postnet {get;set;}
}

And initiailize it from the Dictionary in the other answer like this:

var myVars = new MyVars {
    MailClass = dict["MailClass"],
    Selectivity = dict["Selectivity"],
    MailForeign = dict["MailForeigns"],
    ImbType = dict["ImbType"],
    Postnet = dict["Postnet"]
}

Then, you are dealing with strong type entity that can easily be moved around.

You can then have different types as well, for example you might decide that Postnet is a bool and maybe another int var will come along next week.

public class MyVars {
    public string MailClass {get;set;}
    public string Selectivity {get;set;}
    public string MailForeigns {get;set;}
    public string ImbType {get;set;}

    public bool Postnet {get;set;}
    public int SomeNewVar {get;set;}
}

var myVars = new MyVars {
    MailClass = dict["MailClass"],
    Selectivity = dict["Selectivity"],
    MailForeign = dict["MailForeigns"],
    ImbType = dict["ImbType"],

    Postnet = dict["Postnet"]=="YES",
    SomeNewVar = int.Parse(dict["SomeNewVar"])
}

If you want key-value pair in your text file convert to c# property then I think you must use T4 template.

I use T4 Template for database tables to C# class creator, like as entity framework.
