使用例

すべての名前付きのサーバー変数の名前と値を表示するコード例を次に示します。

Visual Basic

Dim loop1, loop2 As Integer
Dim arr1(), arr2() As String
Dim coll As NameValueCollection
 
' Load ServerVariable collection into NameValueCollection object.
coll=Request.ServerVariables 
' Get names of all keys into a string array.
arr1 = coll.AllKeys 
For loop1 = 0 To arr1.GetUpperBound(0)
   Response.Write("Key: " & arr1(loop1) &
 "<br>")
   arr2 = coll.GetValues(loop1) ' Get all values under this key.
   For loop2 = 0 To arr2.GetUpperBound(0)
      Response.Write("Value " & CStr(loop2) &
 ": " & Server.HtmlEncode(arr2(loop2)) &
 "<br>")
   Next loop2
Next loop1

int loop1, loop2;
NameValueCollection coll;
 
// Load ServerVariable collection into NameValueCollection object.
coll=Request.ServerVariables; 
// Get names of all keys into a string array. 
String[] arr1 = coll.AllKeys; 
for (loop1 = 0; loop1 < arr1.Length; loop1++) 
{
   Response.Write("Key: " + arr1[loop1] + "<br>");
   String[] arr2=coll.GetValues(arr1[loop1]);
   for (loop2 = 0; loop2 < arr2.Length; loop2++) {
      Response.Write("Value " + loop2 + ": " + Server.HtmlEncode(arr2[loop2])
 + "<br>");
   }
}

int loop1, loop2;
NameValueCollection coll;

// Load ServerVariable collection into NameValueCollection object.
coll = get_Request().get_ServerVariables();
// 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: " + 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>"));
    }
}

JScript

var arr1, arr2 : String[]
var coll : NameValueCollection

coll=Request.ServerVariables // Load ServerVariable collection into
 NameValueCollection object.
arr1 = coll.AllKeys // Put names of all keys into a string array.
for(var i=0; i < arr1.Length; i++){
  Response.Write("Key: " + 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>")
  }
}
