1、下载ChinaPay的dll文件，解压放到BIN目录下，共4个文件。
2、引用ChinaPay_Net.dll到项目。
3、申请到的key放到网站，本例是放到根目录key文件夹下：
4、添加类：
using System;
using System.Text;
using System.Web;
using ChinaPay_Net;
/// <summary>
///Chinapay 的摘要说明
/// </summary>
public class Chinapay
{
private static string _MerId = "808080*********";//商户号
private static string _Action = "https://payment.ChinaPay.com/pay/TransGet";
private static string _BgRetUrl = "http://www.XXX.com/Payment/ChinaPayBgRetUrl.aspx";
private static string _PageRetUrl = "http://www.XXX.com/Payment/ChinaPayPageRetUrl.aspx";
string strUrl = HttpContext.Current.Request.PhysicalApplicationPath;
/// <summary>
/// 创建提交表单
/// </summary>
/// <param name="OrdId">订单号，长度11位</param>
/// <param name="Amount">付款金额，最多保留两位有效数字</param>
/// <returns></returns>
public static string getChinaPayForm(string OrderId, decimal Amount, string PrivateValue)
{
string CuryId = "156";
string TransDate = DateTime.Now.ToString("yyyyMMdd");
string TransType = "0001";
StringBuilder sb = new StringBuilder();
if (OrderId.Length != 11)
{
sb.Append("订单号必须为长度11位");
}
else if (Amount <= 0)
{
sb.Append("订单金额必须大于0");
}
else
{
string OrdId = OrderId.Substring(0, 4) + _MerId.Substring(10, 5) + OrderId.Substring(4, 7);
string TransAmt = "000000000000" + Math.Round(Amount, 2, MidpointRounding.AwayFromZero).ToString().Replace(".", "");
TransAmt = TransAmt.Substring(TransAmt.Length - 12, 12);
Chinapay cp = new Chinapay();
string ChkValue = cp.getSign(_MerId, OrdId, TransAmt, CuryId, TransDate, TransType);
sb.Append("<form action=\"" + _Action + "\" method=\"POST\">");
sb.Append("<input type=\"hidden\" name=\"MerId\" value=\"" + _MerId + "\" />");
sb.Append("<input type=\"hidden\" name=\"OrdId\" value=\"" + OrdId + "\" />");
sb.Append("<input type=\"hidden\" name=\"TransAmt\" value=\"" + TransAmt + "\" />");
sb.Append("<input type=\"hidden\" name=\"CuryId\" value=\"" + CuryId + "\" />");
sb.Append("<input type=\"hidden\" name=\"TransDate\" value=\"" + TransDate + "\" />");
sb.Append("<input type=\"hidden\" name=\"TransType\" value=\"" + TransType + "\" />");
sb.Append("<input type=\"hidden\" name=\"Version\" value=\"20040916\" />");
sb.Append("<input type=\"hidden\" name=\"BgRetUrl\" value=\"" + _BgRetUrl + "\" />");
sb.Append("<input type=\"hidden\" name=\"PageRetUrl\" value=\"" + _PageRetUrl + "\" />");
sb.Append("<input type=\"hidden\" name=\"GateId\" value=\"\">");
sb.Append("<input type=\"hidden\" name=\"Priv1\" value=\"" + PrivateValue + "\">");
sb.Append("<input type=\"hidden\" name=\"ChkValue\" value=\"" + ChkValue + "\">");
sb.Append("<input id=\"PostData\" type=\"submit\" value=\"Post\" style=\"display:none;\" />");
sb.Append("</form>");
sb.Append("<script type=\"text/javascript\">document.getElementById(\"PostData\").click();</script>");
}
return sb.ToString();
}
public string getSign(string MerId, string OrdId, string TransAmt, string CuryId, string TransDate, string TransType)
{
NetPayClientClass npc = new NetPayClientClass();
string path = strUrl + "key\\MerPrK.key";
npc.setMerKeyFile(path);
string strChkValue = "";
strChkValue = npc.sign(MerId, OrdId, TransAmt, CuryId, TransDate, TransType);
return strChkValue.Trim();
}
public string signData(string MerId, string SignMsg)
{
NetPayClientClass npc = new NetPayClientClass();
npc.setMerKeyFile(strUrl + "key\\MerPrK.key");
string strChkValueData = "";
strChkValueData = npc.signData(MerId, SignMsg);
return strChkValueData.Trim();
}
public bool getCheck(string MerId, string OrdId, string TransAmt, string CuryId, string TransDate, string TransType, string OrderStatus, string CheckValue)
{
NetPayClientClass npc = new NetPayClientClass();
npc.setPubKeyFile(strUrl + "key\\PgPubk.key");
string strFlag = "";
bool bolFlag = false;
strFlag = npc.check(MerId, OrdId, TransAmt, CuryId, TransDate, TransType, OrderStatus, CheckValue);
if (strFlag == "0")
{
bolFlag = true;
}
return bolFlag;
}
public bool checkData(string PlainData, string CheckValue)
{
NetPayClientClass npc = new NetPayClientClass();
npc.setPubKeyFile(strUrl + "key\\PgPubk.key");
string strFlagData = "";
bool bolFlagData = false;
strFlagData = npc.checkData(PlainData, CheckValue);
if (strFlagData == "true")
{
bolFlagData = true;
}
return bolFlagData;
}
}
5、添加页面，后台代码如下：
using System;
public partial class Payment_ChinaPayPost
{
private string OrderId = RequestString("OrderId");//必选
private decimal Amount = RequestDecimal("Amount");//必选
private string PrivateValue = RequestString("PrivateValue");//可选参数
protected void Page_Load(object sender, EventArgs e)
{
string postData = Chinapay.getChinaPayForm(OrderId, Amount, PrivateValue);
ResponseWrite(postData);
}
}
6、接收返回值：

/// </summary>
public class ChinaPayModel1
{

/// </summary>
