QueryString

Synopsis

NameValueCollection = Request.QueryString

The QueryString collection returns an instance of the NameValueCollection class containing all the keys and values passed as a part of the query string (typically by submitting an HTML form that uses the GET method instead of POST).

Parameters

NameValueCollection

An Object variable of type NameValueCollection.

Example

The example writes the contents of the QueryString collection to the browser: 

Sub Page_Load(  )
   Dim Counter1, Counter2 As Integer
   Dim Keys(), subKeys(  ) As String
   Dim QSColl As NameValueCollection
  
   ' Load QS into NameValueCollection
   QSColl=Request.QueryString
   ' Get keys into an array
   Keys = QSColl.AllKeys
   For Counter1 = 0 To Keys.GetUpperBound(0)
     Message.Text &= "Key: " & Keys(Counter1) & "<br/>"
     subKeys = QSCol1.GetValues(Counter1) 'Get all values under this key
     For Counter2 = 0 To subKeys.GetUpperBound(0)
        Message.Text &= "Value " & CStr(Counter2) & ": " & _
           subKeys(Counter2) & "<br/>"
     Next Counter2
     Message.Text &= "<br/>"
  Next Counter1
End Sub

The following code can be used to post to the example page (note that the form method attribute has been set to GET, which is required for the form value to be sent as part of the query string): 

<html>
   <head>
      <title>Submit a named parameter via POST</title>
   </head>
<body>
   <form id="form1" action="QueryString.aspx" method="GET">
      <h3>Name:</h3>
      <input type="text" name="name">
      <input type="submit">
   </form>
</body>
</html>
