asp.net mvc - Integrate paypal 'Buy now' button programaticaly -

In my site I am now integrating button programming using PayPal.

I have it:

  & lt; Form action = "https://www.sandbox.paypal.com/cgi-bin/webscr" method = "post" style = "margin-top: 30px;" & Gt; & Lt ;! - Specify a Buy Now button. - & gt; & Lt; Input type = "hidden" name = "CMD" value = "_x click" /> & Lt ;! - Identify your business so that you can collect payments. - & gt; & Lt; Input type = "hidden" name = "business" value = "me@email.com" /> & Lt ;! - Specify the details of the items that the buyer will buy. - & gt; & Lt; Input type = "hidden" name = "item_name" value = "your items." / & Gt; & Lt; Input type = "hidden" name = "item_nimer" value ='@Model.OrderId '/ & gt; & Lt; Input type = "hidden" name = "zodiac" value = '@model total' / & gt; & Lt; Input type = "hidden" name = "currency_code" value = "dkk" /> & Lt ;! - No shipping address - & gt; & Lt; Input type = "hidden" name = "no_shipping" value = "1" /> & Lt ;! - Specify a URL for the payment confirmation page and a page that is displayed if the user can cancel the transaction. Specify a URL that can post PayPal IPN message (see details below) - & gt; & Lt; Input type = "hidden" name = "return" value = "http://mysite.com/Order/Complete/" /> & Lt; Input type = "hidden" name = "cancel" "value =" http://mysite.com/Order/Cancel/ "/> & lt; input type =" hidden "name =" notify_url "value => "> /> 
 Do not prompt customers to include a note with their payment - & gt; & lt; input type =" hidden "name =" no_not "value =" 1 "/> & Lt ;! - Display payment button -> gt; & lt; input type =" image "name =" submit "src =" https://www.sandbox.paypal.com/en_US/ I / btn / btn_buynowCC_LG.gif "alt =" PayPal "safe" an easy way to pay online"/>; & Lt; img src =" https://www.sandbox.paypal.com/en_US/i/scr/pixel.gif "width =" 1 "height =" 1 "alt =" "/ & Gt; & lt; / form & gt;
