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
1 /// <summary>
2 /// 工商银行调用接口示例
3 /// </summary>
4 public class ICBCTest
5 {
6 string strCertFN = @"E:\XXXX\public.crt";
7 string strCertFNM = @"E:\XXX\商户.crt";
8 string strKeyFN = @"E:\XXX\商户.key";
9 string strKey = "88888888";

11 /// <summary>

15 public ICBC GetCheckInfo(ICBC argIcbc)
16 {
17 string strMerSignMsg = string.Empty;
18 B2CUtil icbcObj = new B2CUtil();
19
20 if (icbcObj.init(strCertFN, strCertFNM, strKeyFN, strKey) == 0)
21 {
22 argIcbc.MerSignMsg = icbcObj.signC(argIcbc.TranData, argIcbc.TranData.Length);
23 argIcbc.MerCert = icbcObj.getCert(1);
24 argIcbc.TranData = Encode(argIcbc.TranData);
25 }
26 else
27 {
28 return null;
