    मैं वापस कब्जा करना चाहता हूँ उपयोगकर्ता को यह पूछने के लिए कि वह फॉर्म डेटा को कैसे सहेजना चाहता है, कुछ गतिविधि में बटन। क्या यह संभव है?

    मुझे कुछ की तरह (स्यूडोकोड) की आवश्यकता होगी: 

      onBackButtonPressed {AlertDialog ("क्या आप सहेजना चाहते हैं?") अगर (OkPressed) {// किसी भी मदद की सराहना की जाएगी  
     धन्यवाद   
       
     < "post-text" itemprop = "text"> 
     ओवरराइड  ऑन बैकप्रेस ()  आपकी गतिविधि में  
      सार्वजनिक शून्य पर बैकड () {AlertDialog ("क्या आप सहेजना चाहते हैं?") अगर (ठीक दबाया गया है) {// बचत करना है} अन्य {// बैक बटन कार्रवाई के साथ जारी रखें}}

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request.
