公司最近要将原先的1.0.0.0支付接口升级为1.0.0.11 版本，在工行技术人员给出的实例中有ASP、C、JAVA的就是没有ASP.NET与PHP的（先鄙视下）。
下面是根据1.0.0.0转换成1.0.0.11的并参考了http://www.liufangfang.net/blog/148 这个网站
首先将工行提供的 ICBCEBankUtil.dll 注册（如何注册就不说了）注册好后在项目中引用（infosecapi.dll刚开始一直在这个文件上纠缠，结果......）。
然后将public.crt、商户.crt、商户.key 这三个文件放到工程下，
下面就是具体代码了
ICBCTest

OrderInfo 这个为产品信息，这里自己看实际情况来
到此就好了，返回画面就不多写了，只是调用ICBCTest 类中的 GetCheckReturnInfo 方法 从而返回 解密后的值 然后解析解密后的值就可以了。
最后需要注意的是，测试必须在80端口下进行，不然跳过去回报错。
不好意思，前一段时间有点忙，自己还没弄完返回页面就已经发博客了，今天将返回页面也贴出来
