how to convert an instance of an anonymous type to a NameValueCollection

Question

Suppose I have an anonymous class instance

var foo = new { A = 1, B = 2};

Is there a quick way to generate a NameValueCollection? I would like to achieve the same result as the code below, without knowing the anonymous type's properties in advance.

NameValueCollection formFields = new NameValueCollection();
formFields["A"] = 1;
formFields["B"] = 2;

Answer 1

var foo = new { A = 1, B = 2 };

NameValueCollection formFields = new NameValueCollection();

foo.GetType().GetProperties()
    .ToList()
    .ForEach(pi => formFields.Add(pi.Name, pi.GetValue(foo, null)?.ToString()));

Answer 2

Another (minor) variation, using the static Array.ForEach method to loop through the properties...

var foo = new { A = 1, B = 2 };

var formFields = new NameValueCollection();
Array.ForEach(foo.GetType().GetProperties(),
    pi => formFields.Add(pi.Name, pi.GetValue(foo, null).ToString()));
