如何创建类并反序列化来自thirdParty webApi的返回的xml响应？

Question

I am having the following response xml from the thirdParty webApi. i want to get the Order Id from the Xml and save in to my Database and i need other tags like message Error to show to the User. So i want to de-serialize the Responsed xml which is given below. since i am new to this. Please can you help me to de-serialize the following response. Since i don't have a clear idea about it to create a Class for deserialization. Thanks in advance.

<?xml version="1.0" encoding="utf-8"?>
<OrderResult xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <Status>Success</Status>
    <OrderID>159E6B2AE35244DB984384DBD7DC</OrderID>
    <Errors>
        <Error>
            <Code>1000</Code>
            <Message> StopType not valid. Submitted TripSheet data has been ignored.</Message>
            <Severity>Unknown</Severity>
        </Error>
        <Error>
            <Code>1000</Code>
            <Message> StopType not valid. Submitted TripSheet data has been ignored.</Message>
            <Severity>Unknown</Severity>
        </Error>
    </Errors>
</OrderResult>

I assume you will already have the XML as a Stream from the service, so disregard my code for obtaining the Stream, but here is a console app to demonstrate. I generated the OrderResult and OrderResultError classes by copying your xml to the clipboard and pasting in Visual Studio with Edit > Paste Special > Paste XML as Classes

    {
        static void Main(string[] args)
        {
            string xml = @"<?xml version=""1.0"" encoding=""utf-8""?>

            XmlSerializer ser = new XmlSerializer(typeof(OrderResult));
            var orderresult = ser.Deserialize(ms) as OrderResult;

            Console.WriteLine(orderresult.OrderID);
