BizTalk测试映射具有多个输入xml,还是内联C#是问题所在?

blog 为了测试我的映射,但我刚刚尝试了我的第一个多输入映射,它失败了:-(

<ns0:Root xmlns:ns0="http://schemas.microsoft.com/BizTalk/2003/aggschema">
  <InputMessagePart_0>
    ...
  </InputMessagePart_0>
  <InputMessagePart_1>
    ...
  </InputMessagePart_1>
</ns0:Root>

// This is the BizTalk Server 2006 way of calling 
mapInstance.StreamingTransform.Transform(inputStream, 
    mapInstance.TransformArgs, outputStream, resolver);
// This is the R2 way of calling
XmlReader xmlRdr = new XmlTextReader(inputStream);
mapInstance.StreamingTransform.ScalableTransform(xmlRdr, 
    mapInstance.TransformArgs, outputStream, 
    resolver, whitespaceCorrect);

XPathDocument doc = new XPathDocument(inputStream);
mapInstance.Transform.Transform(doc, mapInstance.TransformArgs, outputStream);
