Object ToXml method
Heriyanto Binduni
below:
var orderModel = new OrderModel {
OrderType = "BUY",
Price = 2400,
Lot = 5
};
orderModel.ToJson(); //work fine
orderModel.ToXml(); //error: Cannot access a closed Stream.
but i get an exception message:
Cannot access a closed Stream.
can you tell me what's wrong with my code? fyi, ToJson working fine.
so i suppose to use ToXml method just like ToJson but it seem i'm
wrong.
anyway, tq for your great work.
greeting from indonesia.

tq for your fast response. i try your test case and i got it like
this:
public void Can_toJson_than_toXml()
{
var orderModel = new OrderModel
{
OrderType = "BUY",
Price = 2400,
Lot = 5
};
var json = orderModel.ToJson();
var fromJson = json.FromJson<OrderModel>();
Assert.That(fromJson.OrderType,
Is.EqualTo(orderModel.OrderType));
var xml = orderModel.ToXml();
var fromXml = xml.FromXml<OrderModel>();
Assert.That(fromXml.OrderType,
Is.EqualTo(orderModel.OrderType));
}

so changing this:
using (var reader = new StreamReader(ms))
{
return reader.ReadToEnd();
}
to this:
var reader = new StreamReader(ms);
return reader.ReadToEnd();
will solve the problem.
