Question

I need to serialize the headers object to store it in string format, probably base64.
The Dictionary<String, Object> will only have String or Int values, so there should be no problem.

 Dictionary<String, Object> headers = RequestHeaders.ProcessHeaders(HttpContext.Current); 

Also, of course the point is to be able to deserialize the base64 string back to Dictionary.

Answer 1

You can’t serialize a Dictionary into XML, but you could serialize it into JSON:

string json = JsonConvert.SerializeObject(dictionary, Formatting.None);
byte[] bytes = Encoding.UTF8.GetBytes(json);
string base64String = Convert.ToBase64String(bytes);

To deserialize:

byte[] bytes = Convert.FromBase64String(base64String);
string json = Encoding.UTF8.GetString(bytes);
Dictionary<string, object> deserializedDict = JsonConvert.DeserializeObject<Dictionary<string, object>>(json);
