How to create a C# configuration file

Hello,

Need to create a config file (text file) that contains metrix associated with parameters. Application design doesn't store info need a quick workaround.

Line 1- Height Metres
Line 3- Cost AUD($)
etc

Height, Weight are used for charting.  Comboboxes populated with these strings and values are double arrays.  

Should I parse the text file and insert into a Dictionary<key, value>.

Key equals the name of the parameter and Value is the metrics?

Better approach to achieve this?

Thanks AC

One possible quickest method is: Using XmlSerializer will save lot of coding in mapping values between variables and files as shown in the code below.
public class ConfigItem
        {
            public string Name;
            public double Value;
        }

List<ConfigItem> list = new List<ConfigItem>(); // Dictionary can not be used with xmlserializer
            list.Add(new ConfigItem() { Name = "Height ", Value = 1.5 });
            list.Add(new ConfigItem() { Name = "Cost ", Value = 50.25 });

            // To save the config items to a xml file
            XmlSerializer x = new XmlSerializer(typeof(List<ConfigItem>));
            TextWriter writer = new StreamWriter("myconfig.xml");
            x.Serialize(writer, list);
            writer.Close();

            // to load config items from xml file
            XmlSerializer xs = new XmlSerializer(typeof(List<ConfigItem>));
            TextReader r = new StreamReader("myconfig.xml");
            List<ConfigItem> clist = (List<ConfigItem>)xs.Deserialize(r);
            r.Close();

Another quick method:
Dictionary<string, double> d = new Dictionary<string, double>();
            d["Height"] = 1.5;
            d["Cost"] = 25.50;

            // To save config values in a config txt file
            TextWriter writer = new StreamWriter("myconfig.txt");
            foreach (KeyValuePair<string, double> item in d)
            {
                writer.WriteLine(item.Key + "=" + item.Value);
            }
            writer.Close();

            // To read from config txt file
            Dictionary<string, double> d2 = new Dictionary<string, double>();
            TextReader r = new StreamReader("myconfig.txt");
            while (true)
            {
                string line = r.ReadLine();
                string[] t = line.Split('=');
                d2[t[0]] = Convert.ToDouble(t[1]);
            }
            r.Close();

With a correction in the above code:
...
// To read from config txt file
            Dictionary<string, double> d2 = new Dictionary<string, double>();
            TextReader r = new StreamReader("myconfig.txt");
            while (true)
            {
                string line = r.ReadLine();
                if(line == null) break;
                string[] t = line.Split('=');
                d2[t[0]] = Convert.ToDouble(t[1]);
            }
            r.Close();
