string OrderNumber = "alipay" + DateTime.Now.ToString("yyyyMMddHHmmss");
string app_id = "你的app_id";
string merchant_private_key = "你的應用私鑰";
string alipay_public_key = "你的支付寶公鑰";
string timeout_express = "30m";//訂單有效時間（分鐘）

IAopClient client = new DefaultAopClient(postUrl, app_id, merchant_private_key, format, version, sign_type, alipay_public_key, "UTF-8", false);
AlipayTradeWapPayRequest request = new AlipayTradeWapPayRequest();
request.SetNotifyUrl("支付寶後臺通知的地址");
request.SetReturnUrl("支付寶前臺回跳的地址");
request.BizContent = "{" +
" \"body\":\"對一筆交易的具體描述資訊。如果是多種商品，請將商品描述字串累加傳給body。\"," +
" \"subject\":\"商品描述\"," +

" }";
AlipayTradeWapPayResponse response = client.pageExecute(request);
string form = response.Body.Substring(0, response.Body.IndexOf("<script>"));
return form;
}

寫的挺清楚的了 看完應該都會了 如果還是不明白或者有其他疑問的 可以給我留言 我看到了就回復。
稍後把APP支付的也發上來，使用Hbuilder打包APP呼叫的 也是C#在後臺生成的訂單。
