一、 前期准备
- 手机银行（WAP）B2C在线支付接口说明V1.0.0.6.doc
- 手机银行移动生活商户及门户网站js接口API.doc
- 支付组件ICBCEBankUtil.dll和infosecapi.dll
- 工行联测环境时间查看工具ICBCTime_V20141011.exe
- 测试公钥、商户公钥和私钥
- 个人银行测试帐号
Ps:工行运营提供开发文档时，没有直接提供支付组件ICBCEBankUtil.dll和infosecapi.dll，工行运营说有这个组件在文档中，但是没有找到，工行没有技术提供支持，后来在网上自己找的。
二、 环境搭配
- 复制支付组件ICBCEBankUtil.dll和infosecapi.dll到C盘中System32或System64文件夹下，在DOS窗口下切换目录System32或System64文件夹下 中运行regsvr32 ICBCEBankUtil.dll注册组件，并在项目中引用组件。
- IIS下解析项目，在程序池中修改启用32应用程序
Ps:本人使用的是64位系统，支付组件是放在System64文件夹下的，如果系统是32位,支付组件要放在System32文件夹下。使用DOS命令请使用管理员权限运行，否则注册失败。
三、编码
定义订单实体类：
//基本信息

public string interfaceName { get; set; }
/// <summary>

Ps:
1.在使用测试帐号的时候，订单日期必须与测试服务器一致，可以使用工行提供的工具获取服务器当前时间。
2.运行项目时需要启用32应用程序。
3.测试期间一般是使用H5支付，正式商户号申请完成之后，H5嵌入工行APP,使用工行APP支付。
