我有一个注册表单，我正在接受用户输入并将信息传递到支付网站。支付网站有几个隐藏字段，因此它可以将每个单独的用户区分为唯一的，而不是依赖用户提供的唯一名称。这就是“unique_id”字段，我想要一个随机数作为参数。我将如何进行这项工作，以便每次用户单击附加此代码的按钮时，它都会执行 RNG 并将该号码传递给外部支付网站？

    protected void submitButton_Click(object sender, EventArgs e)
    {
Random randnum = new Random();
int num = randnum.Next();
        {
            NameValueCollection PostFields = new NameValueCollection();
            PostFields.Add("LMID", "345573");
            PostFields.Add("unique_id", RANDOM NUMBER HEEDS TO GO HERE);
            PostFields.Add("sTotal", "150.00");
            PostFields.Add("webTitle", "Conference");
            PostFields.Add("Trans_Desc", "Conference Registration");
            PostFields.Add("contact_info", "Contact admin");
            PostFields.Add("BILL_CUSTOMER_FIRSTNAME", labelFirstName.Text);
            PostFields.Add("BILL_CUSTOMER_LASTNAME", labelLastName.Text);
            PostFields.Add("BILL_ADDRESS1", labelAddress.Text);
            PostFields.Add("BILL_CITY", labelCity.Text);
            PostFields.Add("BILL_STATE", labelState.Text);
            PostFields.Add("BILL_ZIP", labelZip.Text);
            PostFields.Add("BILL_CUSTOMER_PHONE", labelTelephone.Text);
            PostFields.Add("BILL_CUSTOMER_EMAIL", labelEmail.Text);
            RedirectAndPOST(this.Page, "payment website url", PostFields);
        }

这对我来说很好：

    Random random = new Random(); int num = random.Next();

    NameValueCollection PostFields = new NameValueCollection();
    PostFields.Add("LMID", "093204"); 
    PostFields.Add("unique_id", num.ToString());
