我正在使用 asp.net/c# weborms。我在表格中添加了recaptcha，并使用了他们网站上的内容。它需要自定义外观，因此它是这样的：

<div id="recaptcha_widget" style="display:none">

   <div id="recaptcha_image"></div>
   <div class="recaptcha_only_if_incorrect_sol" style="color:red">Incorrect please try again</div>

   <span class="recaptcha_only_if_image">Enter the words above:</span>
   <span class="recaptcha_only_if_audio">Enter the numbers you hear:</span>

   <input type="text" id="recaptcha_response_field" name="recaptcha_response_field" />

   <div><a href="javascript:Recaptcha.reload()">Get another CAPTCHA</a></div>
   <div class="recaptcha_only_if_image"><a href="javascript:Recaptcha.switch_type('audio')">Get an audio CAPTCHA</a></div>
   <div class="recaptcha_only_if_audio"><a href="javascript:Recaptcha.switch_type('image')">Get an image CAPTCHA</a></div>

   <div><a href="javascript:Recaptcha.showhelp()">Help</a></div>

 </div>

 <script type="text/javascript"
    src="http://api.recaptcha.net/challenge?k=your_public_key">
 </script>
 <noscript>
   <iframe src="http://api.recaptcha.net/noscript?k=your_public_key"
        height="300" width="500" frameborder="0"></iframe><br>
   <textarea name="recaptcha_challenge_field" rows="3" cols="40">
   </textarea>
   <input type="hidden" name="recaptcha_response_field"
        value="manual_challenge">
 </noscript>

我需要在表单后面的代码中的 button_click 方法中做什么来检查用户输入的单词是否正确。音频也一样。

谢谢

为什么不使用 reCaptcha 提供的控件？这是控件和快速入门。

Like other validations you just need to check if(Page.IsValid) in behind code. just note that you have to add recaptcha control in your code and then add your customs them.

<recaptcha:RecaptchaControl ID="recaptcha" runat="server" PublicKey="your_public_key"
PrivateKey="Your_private_key" Theme="custom" />
<div id="recaptcha_widget" style="display:none">
<div id="recaptcha_image"></div>
<div class="recaptcha_only_if_incorrect_sol" style="color:red">Incorrect please try again</div>
