谢谢你们所有的帮助。我解决了这个问题。

Thanks guys for all your help. I solved the problem.

在SOAP请求的SOAPACTION字段有错误的URI

The 'SoapAction' field in the soap request had the wrong URI

我建议使用HTTP嗅探器。 。HTTP嗅探器会显示SOAP性能

I recommend using a HTTP sniffer. The http sniffer will show the SOAP properties.

SOAPAction报属性应该是这样的：的 http://tempuri.org/YourServiceMethodName

The "SOAPAction" property should have something like : http://tempuri.org/YourServiceMethodName
