c# - MTOM-在VS 2010中读取时遇到无效的MIME内容类型 header

我在磁盘上有一个MTOM响应，我正在尝试加载和解析响应。
创建MTOM阅读器时，我不断收到错误消息。

Invalid MIME content-type header encountered on read.

这是错误还是内容类型的标头确实意味着Visual Studio无法理解内容类型？

MIME-Version: 1.0
Content-Type: Multipart/Related;boundary=DeltaSync91ABCB4AF5D24B8F988B77ED7A19733D?MTOM;
    type="application/xop+xml";
    start="<[email protected]>";

这是创建MTOM阅读器的简单代码。

XmlDictionaryReader mtomReader = XmlDictionaryReader.CreateMtomReader
            (
             fStream,
             Encoding.UTF8,
             XmlDictionaryReaderQuotas.Max
            );

最佳答案

您的数据中存在几个问题：


您需要在Content-Type标头中对边界字符串进行编码，因为它包含?字符。
第5行到最后一行是缩进的-您需要删除前导空格
您缺少结尾边界字符串


这是对我有用的修改后的内容：

MIME-Version: 1.0
Content-Type: Multipart/Related;boundary="DeltaSync91ABCB4AF5D24B8F988B77ED7A19733D?MTOM"";
    type="application/xop+xml"";
    start="<[email protected]>"";
