如何創建類並反序列化來自thirdParty webApi的返回的xml響應？

Question

我從thirdParty webApi獲得以下響應xml。 我想從Xml獲取訂單ID並保存到我的數據庫中，我需要其他標簽（例如消息Error）顯示給用戶。 所以我想反序列化下面給出的xml。 因為我是新來的。 請您幫我反序列化以下響應。 由於我沒有一個清晰的主意來創建反序列化的類。 提前致謝。

<?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>

我假設您已經將XML作為服務中的流，因此無需考慮獲取該Stream的代碼，但這是一個演示控制台的應用程序。 我通過將xml復制到剪貼板並在Visual Studio中使用“編輯”>“選擇性粘貼”>“將XML粘貼為類”來生成OrderResult和OrderResultError類。
