我必须通过网络服务上传文件。 Web服务支持MTOM。因为文档可能非常大，我想在流中上传文档。 问题是Visual Studio将数据的属性deserailize为字节数组（byte []）。所以我必须在上传之前将整个文档加载到内存中。
如何使用Stream属性对wsdl进行反序列化？ 如果不可能wsdl看起来像.net那么deserialice它是否正确？
WSDL看起来像：
<?xml version="1.0" encoding="UTF-8" ?>

要反序列化为Stream的属性位于以下行：
<xsd:element name="bytes" minOccurs="0" maxOccurs="1" type="xsd:base64Binary" xmlns:xmime="http://www.w3.org/2005/05/xmlmime" xmime:expectedContentTypes="application/octet-stream" />
