将 Paypal 与定制系统集成时，我设法将其设置为发送设定值，例如 25 英镑，但不是篮子中的变量，例如“GrandTotal”，这取决于客户在购物车中输入的内容（我有创建了我自己的购物车。）

请参考以下代码： 

<%@ page language="C#"%>
<%@ Register TagPrefix="webxelcart" Namespace="WebXelCart" Assembly="WebXelCart" %>
<script runat="server">

void btnCheckout_Click(object sender, System.EventArgs e)
{
WriteToDB1.Save();
}

void WriteToDB1_RecordInserted(object sender, WebXelCart.RecordInsertedEventArgs e)
{
Cart1.OrderID = e.Identity;
SaveOrder1.Save();
}

    protected void Page_Load(object sender, EventArgs e)
    {

    }
</script>

<!doctype html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">


<script runat="server">  
    void Cart1_Load(object sender, System.EventArgs e)   
    { 
    if(Cart1.GrandTotal > 100){Cart1.CarriageCost = 0;} 
    else{Cart1.CarriageCost = 15;}  
    }  
    </script>

任何有关如何获取“GrandTotal”变量并将其发送到 Paypal 的帮助将不胜感激。

谢谢

您不能form tag在 ASP.Net 页面中创建多个（除非 iframe），因为 ASP.Net 只允许在页面中使用一个表单标签。

你想在后面的代码中类似这样。它基本上收集用户输入的金额和数量，然后将其发送回 PayPal。

protected void btnCheckout_Click(object sender, EventArgs e) {

 string paypalUrl = IsTestMode ? 
   "https://www.sandbox.paypal.com/us/cgi-bin/webscr" : 
   "https://www.paypal.com/us/cgi-bin/webscr";

 var builder = new StringBuilder();

 builder.Append(paypalUrl);

 builder.AppendFormat("?cmd=_xclick&business={0}", 
    HttpUtility.UrlEncode(you@youremail.com));

 builder.Append("&lc=US&no_note=0&currency_code=GBP");

 builder.AppendFormat("&item_name={0}", 
    HttpUtility.UrlEncode(YourItemName));

 builder.AppendFormat("&amount={0}", AmountTextBox.Text);

 builder.AppendFormat("&return={0}", 
    HttpUtility.UrlEncode("http://mysite.cm/ReturnUrl"));

 builder.AppendFormat("&cancel_return={0}", 
    HttpUtility.UrlEncode("http://mysite.cm/CancelUrl"));

 builder.AppendFormat("&undefined_quantity={0}", QuantityTextBox.Text);

 HttpContext.Current.Response.Redirect(builder.ToString());

}
