C#.net 支付宝接口
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="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
read;//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。

这个函数就是返回生成的地址，里面注释掉的看你自己需要可以添加进去，然后就是md5码的问题，现在用默认的md5生成程序对中文的支持只限于GB2312，而支付宝使用的是GBK，虽然两个编码的内容GBK兼容GB2312但是毕竟两个编码方式不同，所以会产生错误，如果用英文或者数字不会有问题。上面下载里面带的一个md5.asp的算法支持中文。
现在已经可以跳转到支付宝的页面了，而我们这边就要自己记录用户的信息已经生成的定单编号，这样在支付宝返回信息的时候来查询。在设定了返回地址后，我们就要看接收页面了。

msg_id,order_no,gross,buyer_email,buyer_name,buyer_address,buyer_zipcode,buyer_tel ,buyer_mobile,action,s_date,ac,notify_type;
string returnTxt;//返回给支付宝通知接口的结果
string alipayNotifyURL;//支付宝查询接口URL
string myalipayEmail;//商户的支付宝Email
string Resp;
returnTxt = "N";
alipayNotifyURL = ConfigurationSettings.AppSettings["interfaceback"];//支付宝查询接口地址
myalipayEmail = ConfigurationSettings.AppSettings["account"];//填写您的支付宝帐号
//检查支付宝通知接口传递过来的参数是否合法
msg_id = newop.DelStr(Request["msg_id"]);

C#支付宝接口标准简化版
最近整合做的商城整合支付宝做了一个接口大家可以参考一下
通过测试没有问题的
演示可以到这里试试
