How can I convert a class into Dictionary<string,string>?

This is the recipe: 1 reflection, 1 LINQ-to-Objects!

 someObject.GetType()     .GetProperties(BindingFlags.Instance | BindingFlags.Public)          .ToDictionary(prop => prop.Name, prop => (string)prop.GetValue(someObject, null))

Since I published this answer I've checked that many people found it useful. I invite everyone looking for this simple solution to check another Q&A where I generalized it into an extension method: Mapping object to dictionary and vice versa

Here a example with reflection without LINQ:

    Location local = new Location();    local.city = "Lisbon";    local.country = "Portugal";    local.state = "None";    PropertyInfo[] infos = local.GetType().GetProperties();    Dictionary<string,string> dix = new Dictionary<string,string> ();    foreach (PropertyInfo info in infos)    {        dix.Add(info.Name, info.GetValue(local, null).ToString());    }    foreach (string key in dix.Keys)    {        Console.WriteLine("nameProperty: {0}; value: {1}", key, dix[key]);    }    Console.Read();

I would like to add an alternative to reflection, using JToken. You will need to check the benchmark difference between the two to see which has better performance.

var location = new Location() { City = "London" };var locationToken = JToken.FromObject(location);var locationObject = locationObject.Value<JObject>();var locationPropertyList = locationObject.Properties()    .Select(x => new KeyValuePair<string, string>(x.Name, x.Value.ToString()));

Note this method is best for a flat class structure.
