Getting data from a form in ASP.NET C#

This is a small tutorial on getting/reading submitted data from ASP.NET pages.

In PHP, you write a form, put in your inputs (i.e. test_name), then some buttons. Usually you would catch this by doing a:

echo $_POST['test_name'];

In ASP.NET C# you get your post variables by using Request.Form:

Request.Form["test_name"]

To send the data, with your submit button, simply have the METHOD=”?action=update” or if you’re using an ASP Button control, the PostBackURL should be “?action=update”

Now you need to catch the post back, and do something with the information you’ve sent to the server.

To see what button has been clicked, use QueryString:

Request.QueryString["action"];

Put all this together:

string action = Request.QueryString["action"]; if (action == "update") { name = Request.Form["test_name"]; }

Easy!
