Reading
User Input
Another important feature of dynamic
web pages is that you can read user input.
Input is read by the Request[]
function, and posting (input) is tested by the IsPost condition:
Example
@{
var totalMessage = "";
if(IsPost)
{
var num1 = Request["text1"];
var num2 = Request["text2"];
var total = num1.AsInt() + num2.AsInt();
totalMessage = "Total = " + total;
}
}

<body style="background-color: beige; font-family: Verdana, Arial;">
<form action="" method="post">
<p><label for="text1">First Number:</label><br>
<input type="text" name="text1"></p>
<p><label for="text2">Second Number:</label><br>
<input type="text" name="text2"></p>
<p><input type="submit" value=" Add "></p>
</form>

</body>
var totalMessage = "";
if(IsPost)
{
var num1 = Request["text1"];
var num2 = Request["text2"];
var total = num1.AsInt() + num2.AsInt();
totalMessage = "Total = " + total;
}
}
