如何從其他頁面返回頁面？

Question

我已經調用了一個重定向到另一個頁面的方法。完成另一頁後，我想從上一頁返回。這是我的代碼：

private string RedirectToPaymentGateway_v3(string MTrackid, string MAmount,string MSType) 
{ 
    HttpContext.Current.Session["pgMTrackid"] = MTrackid; 
    HttpContext.Current.Session["pgMAmount"] = MAmount; 
    HttpContext.Current.Session["pgMStype"] = MSType; 
    HttpContext.Current.Response.Redirect("DoPost.asp", true); 

    return ""; 
} 

完成dopost.asp我想要在我打電話DoPost.asp頁面後返回。

Answer 1

經過原點頁面作爲參數，並隨後重定向到它：

private string RedirectToPaymentGateway_v3(string MTrackid, string MAmount,string MSType) 
{ 
    HttpContext.Current.Session["pgMTrackid"] = MTrackid; 
    HttpContext.Current.Session["pgMAmount"] = MAmount; 
    HttpContext.Current.Session["pgMStype"] = MSType; 
    HttpContext.Current.Response.Redirect("DoPost.asp?ReturnUrl=" + 
Server.UrlEncode(Request.Url.ToString()); 

    return ""; 
} 

，然後在DoPost.asp處理後做

Response.Redirect(Server.UrlDecode(Request.Querystring["ReturnUrl"]));
