NameValueCollection Serialization Deserialization

[Guest]

We are trying to serialize the Request.ServerVariables collection
(NameValueCollection) to an XML formatted string, to insert into a database.
The problem we are running into is that most of the example that we find
discuss writing to a file. Does anyone have a simple function to do this?

We would also like to deserialize the string from the database back into a
NameValueCollection.

It's sad, but you can't use the XmlSerializer for this. the only easy/good
alternative I know of is to use the SoapFormatter:

NameValueCollection values = new NameValueCollection();
values.Add("one", "two");
values.Add("a", "b");

SoapFormatter ser = new SoapFormatter();
MemoryStream ms = new MemoryStream();
ser.Serialize(ms, values);
byte[] b = ms.GetBuffer();
string s = Encoding.Default.GetString(b);
ms.Close();

you'll need to add a reference to
System.Runtime.Serialization.Formatters.Soap.dll

Thanks Karl! This will help tremendously. Can this string be deserialized
back into a NameValueCollection as well?

Yes, if you pull up the documentation for SoapFormatter you'll see....but,
as you probably could have guessed, there's a Deserialize function
