[C++]
public: String* GetValues(String* header)  __gc[];
[JScript]
public override function GetValues(
   header : String) : String[];

使用例

[Visual Basic, C#, C++] GetValues メソッドを使用して、 WebHeaderCollection の各ヘッダーの値の配列を取得する例を次に示します。

 
'Create a web request for "www.msn.com".

'Get the associated response for the above request.
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)

'Get the headers associated with the response.
