微信企业付款开发 C#

一、第一步:需要准备的东东

<add key="sAppID" value="wxf2303b260*******"/>                       // 开发者应用ID ,如图一

<add key="sAppSecret" value="5b83018b0b69c4231c14a2a25*******"/>    //开发者应用密钥,如图一

<add key="sPartnerKey" value="E07D38C4EC0C9B42BF808633*******"/>   //商户秘钥           如图二

<add key="sPartner" value="**********"/>   // 商户号            申请微信支付通过后,收到的邮件里面有, 10位的商户号

(图二,你自己设置的32位秘钥),登录地址:https://pay.weixin.qq.com/index.php/home/login?return_url=%2F

二、第二步:安装证书,windows下面选择.p12格式的证书;取证书时一定得用 绝对路径(如:D:/wwwroot/BusinessCard/weixin/businesscard/cert/apiclient_cert.p12)

      证书pkcs12格式 (apiclient_cert.p12)

三、第三步:帐户里面必须有钱,如下图
