下面的示例代码演示了一个方法，该方法使用 HttpResponseHeaderCollection 对象的 Connection 属性获取和设置 HttpResponseMessage 对象上的 Connection 标头。

// Connection:keep-alive
// HttpConnectionOptionHeaderValueCollection, a collection of
// HttpConnectionOptionHeaderValue which just has a Token (string)
// 
// This is the same type as on the request
    void DemoConnection(HttpResponseMessage response) {
        var h = response.Headers;
        h.Connection.TryParseAdd("close");
        h.Connection.TryParseAdd("some,values");
        h.Connection.Add(new HttpConnectionOptionHeaderValue("last"));

        var header = h.Connection;
        uiLog.Text += "\nCONNECTION HEADER\n";
        foreach (var item in header) {
            uiLog.Text += String.Format("Token: {0}  ToString: {1}\n", item.Token, item.ToString());
        }
        uiLog.Text += String.Format("Connection: {0}\n", header.ToString());
    }
