Question

我正在尝试使用使用MTOM格式上传文档的Web服务。我使用了此自定义绑定：

    Dim myBinding As New CustomBinding()
    myBinding.Elements.Clear()
    myBinding.Elements.Add(New MtomMessageEncodingBindingElement(MessageVersion.Soap11, Encoding.UTF8))
    myBinding.Elements.Add(New HttpsTransportBindingElement() With {.TransferMode = TransferMode.Streamed})

事实是文件上传正载，我从服务中得到响应，说上传还可以，但是似乎自定义贴布无法读取响应并返回一个例外：

“错误创建错误MTOM消息的阅读器“

和内部的启动是：

“ MIME零件，带有content-id＆lt; a35854a.245c5.5f.180a95c85a5a5.n7ff5＆gt; gt;”

这是MTOM请求发送给我与Fiddler获得的WS的：

这是WS响应，自定义响应无法正确阅读：

有什么想法，为什么我会在响应中遇到错误？

我还注意到，当我从服务中遇到错误时，我使用的自定义订阅能够使服务的响应逐渐化，响应是：

--MIME_Boundary
Content-ID: <http://tempuri.org/0>
Content-Type: application/xop+xml; type="text/xml"; charset=utf-8
Content-Transfer-Encoding: 8bit

--MIME_Boundary--

但是有什么区别？为什么可以在没有错误的情况下处理此响应，但第一个响应却没有？例外说，“ Mime的含量为content-iD＆lt; a35854a.245c5.5f.180a95c85a5a5.n7ff5＆gt;找不到”， 为什么找不到，而是“ content-id： http://tempuri.org/0 ”没有产生同样的例外吗？
