MVC Tempdata, Peek and Keep Difference Cleared

Condition 1 (Not read): If you set a “TempData” inside your action and if you do not read it in your view, then “TempData” will be persisted for the next request.

Condition 2 (Normal Read): If you read the “TempData” normally like the below code, it will not persist for the next request

stringstr = TempData[“MyData”];

Even if you are displaying, it’s a normal read like the code below:

@TempData[“MyData”];

Condition 3 (Read and Keep): If you read the “TempData” and call the “Keep” method, it will be persisted.

@TempData[“MyData”];
TempData.Keep(“MyData”);

Condition 4 ( Peek and Read): If you read “TempData” by using the “Peek” method, it will persist for the next request.

stringstr = TempData.Peek("Td").ToString();
