How to get POST and GET data from a FORM in ASP.NET

Question

I need to get an understanding about how you can handle get and post data in a form in asp.net in these 2 situations:

You submit a form with GET method: 
action: "form.php" 
parameters: text1=test

You submit a form with POST method: 
action: "form.php?text1=sometext" 
parameters: text1=somedifferenttext

I know these 3 commands:

String val1 = Page.Request["text1"];
String val2 = Page.Request.Form["text1"];
String val3 = Page.Request.QueryString["text1"];

I wonder what are the exact commands to access get and post variables directly?

your actions are backwards above. GET uses ? format in the URL. — Lou Franco, Dec 05 '10 at 20:37
@Lou Franco - so does POST. Both GET and POST have QS, POST also has a request body. — RPM1984, Dec 05 '10 at 21:20

Get variables are stored in the query string:

String getText1 = Page.Request.QueryString["text1"];

Post variables are stored in the form:

String postText1 = Page.Request.Form["text1"];

If you want to know more about the difference between Get and Post variables, I'd suggest having a read of this question: When do you use POST and when do you use GET?

For a GET, Page.Request.RawUrl will get you the original querystring. You need to parse the whole URL to get it.

If it's a POST, read it from Page.Request.InputStream

It might also be useful to know that both Page.Request.Form and Page.Request.QueryString are NameValueCollection objects. So if you want to iterate over their keys, you can use Page.Request.Form.Keys and Page.Request.QueryString.Keys.
