Property Value
A NameValueCollection containing the collection of query string variables sent by the client. For example, If the request URL is http://www.contoso.com/default.aspx?id=44 then the value of QueryString is "id=44".The following code example accepts the query string from a client form (with a GET method attribute) and writes out the names and values of each named input element on the form. Place this code on the ASP.NET page referenced by the form's ACTION attribute.
int loop1, loop2;
// Load NameValueCollection object.
NameValueCollection coll = get_Request().get_QueryString();
// Get names of all keys into a string array.
String arr1[] = coll.get_AllKeys();
for (loop1 = 0; loop1 < arr1.length; loop1++) {
get_Response().Write(("Key: " +
get_Server().HtmlEncode(arr1[loop1]) + "<br>"));
String arr2[] = coll.GetValues(arr1[loop1]);
for (loop2 = 0; loop2 < arr2.length; loop2++) {
get_Response().Write(("Value " + loop2 + ": "
+ get_Server().HtmlEncode(arr2[loop2]) + "<br>"));
}
}
var arr1, arr2 : String[] var coll : NameValueCollection coll=Request.QueryString // Load Form variables into NameValueCollection variable. arr1 = coll.AllKeys // Get names of all keys into a string array. for(var i=0; i < arr1.Length; i++){ Response.Write("Key: " + Server.HtmlEncode(arr1[i]) + "<br>") arr2 = coll.GetValues(i) // Get all values under this key. for(var j=0; j < arr2.Length; j++){ Response.Write("Value " + j + ": " + Server.HtmlEncode(arr2[j]) + "<br><br>") } }
