WebPages Objects

ASP.NET WebPages provides built-in objects that help you interact with the server, manage requests, and store data. These objects include Request, Response, Session, and Application.

Key Topics

Request Object

Example

@{
    var userInput = Request["input"];
}

<form method="get">
    <input type="text" name="input" placeholder="Enter something" />
    <button type="submit">Submit</button>
</form>

<p>You entered: @userInput</p>

Explanation: The Request object retrieves data sent via GET or POST methods. Here, it fetches the value of the input field.

Additional Example

@{
    var queryParam = Request.QueryString["id"];
}

<p>Query Parameter: @queryParam</p>

Explanation: The Request.QueryString property accesses query string parameters sent in the URL.

Response Object

Example

@{
    Response.Redirect("/Home");
}

Explanation: The Response.Redirect method sends the user to a different page.

Session Object

Example

@{
    Session["Username"] = "JohnDoe";
}

<p>Welcome, @Session["Username"]!</p>

Explanation: The Session object stores user-specific data that persists across pages during a user session.

Key Takeaways

  • The Request object retrieves user input and query string data.
  • The Response object manages server responses and redirections.
  • The Session object allows for temporary storage of user-specific data.
