太长..只是说下别的.

为什么不直接用生成的代理类?

参见以上silverlight code；

看了一下你的代码，两个地方：

1、你GetEncodeString（）是用来干吗的？

　　我觉得你应该直接将你的soap类型的xml字符串，直接转成bytes，然后写到stream里面就可以了，调用GetEncodeString没必要。

2、ContentType你确定你用soap的时候不应该写application/soap+xml？

      当然，有些服务器经过配置或者一些人手写的不严谨的服务器会无视ContentType的错误或者不符合规范，但是，按照SOAP的规范，请求类型应该是POST（这点你对了），请求的ContentType类型应该是application/soap+xml，具体数据内容放在Stream中。就这三点。

好了，总结以上两点，希望对你有帮助。
