如何使用沙箱测试单笔转账到支付宝（.net版）

说明： 
本帖是利用支付宝沙箱测试“单笔转账到支付宝账户”，demo中会配置个人的沙箱账号信息，方便大家测试。 
测试环境：visual studio 2010及以上+.NET framework 3.5及以上 

注意事项： 
 1.目前仅支持账户余额渠道付款。 
 2.转账额度 
   1）单日转出累计额度为100万元。 
   2）转账给个人支付宝账户，单笔最高5万元；转账给企业支付宝账户，单笔最高10万元。 

特殊逻辑注意点： 
 1）如果商户重复请求转账，支付宝会幂等返回成功结果，商户必须对重复转账的业务做好幂等处理；如果不判断， 
 存在潜在的风险，商户自行承担因此而产生的所有损失。 
 2）如果调用alipay.fund.trans.toaccount.transfer掉单时，或返回结果code=20000时，或返回结果code=40004， 
 sub_code= SYSTEM_ERROR时，请调用alipay.fund.trans.order.query发起查询，如果未查询到结果， 
 请保持原请求不变再次请求alipay.fund.trans.toaccount.transfer接口。 
 3）商户处理转账结果时，对于错误码的处理，只能使用sub_code作为后续处理的判断依据， 
 不可使用sub_msg作为后续处理的判断依据。 

参数解读： 
 1.amount 转账金额，只支持2位小数，小数点前最大支持13位，金额必须大于等于0.1元。 
 2.payer_show_name付款方姓名（最长支持100个英文/50个汉字）。显示在收款方的账单详情页。如果该字段不传 
则默认显示付款方的支付宝认证姓名或单位名称。 
 3.payee_real_name收款方真实姓名（最长支持100个英文/50个汉字），如果本参数不为空，则会校验该账户在支付宝 
登记的实名是否与收款方真实姓名一致。 
 4.remark转账备注（支持200个英文/100个汉字）。当付款方为企业账户，且转账金额达到（大于等于）50000元， 
 remark不能为空。收款方可见，会展示在收款用户的收支详情中。 


测试流程（声明：本demo仅做参考测试使用） 

1.下载sdk，导入运行环境：[url]https://docs.open.alipay.com/54/103419[/url]

2.在Config文件中配置基本信息， 
我这边配置的是沙箱环境下的，如果要测试正式环境的记得修改支付宝网关（ serverUrl）去掉“dev”

3.测试接口 当收款方类型PayeeType=ALIPAY_USERID：pid，PayeeAccount=pid（以2088开头的16位纯数字） 
当收款方类型PayeeType=ALIPAY_LOGONID，PayeeAccount=支付宝账号

如果你传入的手机号码对应多个支付宝账号，则会报该"手机号对应多个支付宝账户，请传入收款方姓名确定正确的收款账号"

当报该错时，可以传入payee_real_name收款方真实姓名（最长支持100个英文/50个汉字）进行支付，前提是两个账号真实姓名不一样，如果一样则只能传邮箱号，或者PayeeType=ALIPAY_USERID，PayeeAccount=pid进行解决
