  1. What is the use of Keep and Peek in “TempData”?

    Once “TempData” is read in the current request it’s not available in the subsequent request. If we want “TempData” to be read and also available in the subsequent request then after reading we need to call the “Keep” method as shown in the code below.


    The more shortcut way of achieving the same is by using “Peek”. This function helps to read as well advices MVC to maintain “TempData” for the subsequent request.

    string str = TempData.Peek("Td").ToString();
