先给你参考一下如下的东西：
支付宝Payto接口的c#.net实现
如果还不了解支付宝payto原理的可以在这里下文档和演示 http://dev.alipay.com/download/alipay_docs.rar
集成演示指南：http://dev.alipay.com/download/yanshi.zip

它现在这种支付方式比较多象网银在线等使用的方法都是url验证，就是通过url参数和一个这些url参数的md5编码来确认这个连接的正确性，支付宝在你购买成功后跳转自定义连接的时候会传2次过来，第一次是数据底层请求，第二次是web请求，而只有第一次有验证码，这个只能通过记录下来才看的到，因为两次请求间隔很小，如果光显示的话最后的结果是被第二次覆盖了的。所以在接收的时候就要设定接收条件，一种是没有notify_type参数的，一种是有的。

我们先来看一下创建一个连接地址
t1=ConfigurationSettings.AppSettings[ "interface "];//支付接口,就是给的一个连接地址
t2=ConfigurationSettings.AppSettings[ "account "];//支付宝帐户你的帐户
t3=ConfigurationSettings.AppSettings[ "password "];//安全校验码，设置的商家验证码
t4= "images/logo_zfbsmall.gif ";//按钮图片地址
t5= "test ";//悬停说明
cmd= "0001 ";//默认
subject= "item ";//商品名称
body= "decrip ";//描述
order_no=;//定单号，用户自己生成，方便自己管理 prices=100;//价格0.01～50000.00
rurl= "http://www.xxx.com/ ";//商品展示网址
types= "1 ";//1：商品购买2：服务购买3：网络拍卖4：捐赠
number= "1 ";//购买数量
transport= "3 ";//1：平邮2：快递3：虚拟物品
ordinary_fee= " ";//平邮运费
express_fee= " ";//快递运费
readonlys= "true ";//交易信息是否只读
buyer_msg= " ";//买家给卖家的留言
buyer= " ";//买家Email
buyer_name= " ";//买家姓名
buyer_address= " ";//买家地址
buyer_zipcode= " ";//买家邮编
buyer_tel= " ";//买家电话号码
buyer_mobile= " ";//买家手机号码
partner=ConfigurationSettings.AppSettings[ "partenid "];//合作伙伴ID,这个是固定的
上面就是要提供得基本信息，然后就是生成支付宝得连接，也就是给支付宝提供一条带验证的购买信息。
