如何在asp.net webform中使用paypal按钮

   // 创建一个Payment对象

   var payment = new PayPal.Api.Payment()

   {

       intent = "sale",

       payer = new PayPal.Api.Payer() { payment_method = "paypal" },

       transactions = new List<PayPal.Api.Transaction>()

       {

           new PayPal.Api.Transaction()

           {

               amount = new PayPal.Api.Amount()

               {

                   currency = "USD",

                   total = "10.00" // 设置支付金额

               },

               description = "Payment description" // 设置支付描述

           }

       },

       redirect_urls = new PayPal.Api.RedirectUrls()

       {

           return_url = "http://yourwebsite.com/return", // 设置支付成功后的返回URL

           cancel_url = "http://yourwebsite.com/cancel" // 设置支付取消后的返回URL

       }

   };

   // 创建支付并获取支付链接

   var createdPayment = payment.Create(apiContext); // apiContext是您的API凭证

   // 重定向到PayPal支付页面

   Response.Redirect(createdPayment.GetApprovalUrl());
