Amazon XML反序列化處理報告並獲取空值

Question

我正在嘗試將xml文件讀入類以返回其值。 這些類是通過xsd.exe從Amazon的xsd文件創建的。 我用來嘗試反序列化的代碼是：

string FeedSubmissionID = "8395421750";
FileStream responseFile = new FileStream(("d:/Amazon/SubmissionResult-" +  FeedSubmissionID + ".txt"), FileMode.Open, FileAccess.Read);           
ProcessingReport _report = new ProcessingReport();
XmlSerializer _des = new XmlSerializer(typeof(ProcessingReport), new XmlRootAttribute("AmazonEnvelope"));
_report = (ProcessingReport)_des.Deserialize(responseFile);

我在ProcessingReport中使用的代碼是：

最后是xml文件：

        <ProcessingSummary>
            <MessagesProcessed>1</MessagesProcessed>
            <MessagesSuccessful>0</MessagesSuccessful>
            <MessagesWithError>1</MessagesWithError>
            <MessagesWithWarning>0</MessagesWithWarning>
        </ProcessingSummary>
        <Result>
            <MessageID>1</MessageID>
            <ResultCode>Error</ResultCode>
            <ResultMessageCode>5000</ResultMessageCode>
            <ResultDescription>XML Parsing Error at Line 22, Column 24: cvc-minLength-valid: Value &apos;&apos; with length = &apos;0&apos; is not facet-valid with respect to minLength &apos;1&apos; for type &apos;LongStringNotNull&apos;.</ResultDescription>
            <AdditionalInfo>
                <SKU>MySKU</SKU>
            </AdditionalInfo>
        </Result>
    </ProcessingReport>
</Message>
</AmazonEnvelope>

返回的_report對象具有所有空值。

誰能看到我哪里出問題了？

Answer 1

問題解決了。

需要發生的是，需要將Amazon feed的結果流首先保存到文件，然后訪問創建的文件並讀入類。 而我試圖直接從流中讀取結果。

希望這對別人有幫助
