Examples

The following example shows how to read the values in the form collection posted from a browser. Each name/value pair in the collection represents a control in the form and its value.

Visual Basic

Dim loop1 As Integer
Dim arr1() As String
Dim coll As NameValueCollection

' Load Form variables into NameValueCollection variable.
coll=Request.Form

' Get names of all forms into a string array.
arr1 = coll.AllKeys
For loop1 = 0 To arr1.GetUpperBound(0)
   Response.Write("Form: " & arr1(loop1) & "<br>")
Next loop1

int loop1;
NameValueCollection coll;

//Load Form variables into NameValueCollection variable.
coll=Request.Form;
// Get names of all forms into a string array.
String[] arr1 = coll.AllKeys;
for (loop1 = 0; loop1 < arr1.Length; loop1++) 
{
   Response.Write("Form: " + arr1[loop1] + "<br>");
}

int loop1;
NameValueCollection coll;

//Load Form variables into NameValueCollection variable.
coll = get_Request().get_Form();
// Get names of all forms into a string array.
String arr1[] = coll.get_AllKeys();
for (loop1 = 0; loop1 < arr1.length; loop1++) {
    get_Response().Write(("Form: " + arr1[loop1] + "<br>"));
}

JScript

var arr1 : String[]
var coll : NameValueCollection

coll=Request.Form   // Load Form variables into NameValueCollection variable.
arr1 = coll.AllKeys // Get names of all forms into a string array.
for(var i=0; i < arr1.Length; i++){
  Response.Write("Form: " + arr1[i] + "<br>")
}
