Implementing reCaptcha in ASP.NET
问题 I am trying to insert a captcha in my ASP.NET code. Basically, in the lbt_proceed_click() method, I want the browser to proceed to the next page using Response.Redirect("foo") only if the captcha entered is correct. I searched, but could not find a solution, especially since I am not using a form to send data, but writing to a database directly, and then moving to the next page using Response.Redirect() . 回答1: go to the reCAPTCHA site and register for a unique key Download reCAPTCHA .NET
