推荐答案

添加到 System.Net.Http.Formatting.dll 参考，并使用<$ C $在的Htt presponseHeadersExtensions 类中定义的C> AddCookies 扩展方法。

Add a reference to System.Net.Http.Formatting.dll and use the AddCookies extension method defined in the HttpResponseHeadersExtensions class.

下面是一个博客文章描述这种方法和 MSDN主题

如果该程序集是不是一个选择，这是我的旧的答案在此之前的是一个选项：

If that assembly isn't an option for you, here's my older answer from before this was an option:

旧的答案如下

我preFER 的Htt presponseMessage 的领域内保持无出血到的HttpContext其中，一个方法不如单元测试和并不总是根据宿主应用：

I prefer an approach that stays within the realm of HttpResponseMessage without bleeding into the HttpContext which isn't as unit testable and does not always apply depending on the host:

/// <summary>
/// Adds a Set-Cookie HTTP header for the specified cookie.
/// WARNING: support for cookie properties is currently VERY LIMITED.
/// </summary>
internal static void SetCookie(this HttpResponseHeaders headers, Cookie cookie) {
    Requires.NotNull(headers, "headers");
    Requires.NotNull(cookie, "cookie");

    var cookieBuilder = new StringBuilder(HttpUtility.UrlEncode(cookie.Name) + "=" + HttpUtility.UrlEncode(cookie.Value));
    if (cookie.HttpOnly) {
        cookieBuilder.Append("; HttpOnly");
    }

    if (cookie.Secure) {
        cookieBuilder.Append("; Secure");
    }

    headers.Add("Set-Cookie", cookieBuilder.ToString());
}

然后，可在这样的反应的cookie：

Then you can include a cookie in the response like this:

HttpResponseMessage response;
response.Headers.SetCookie(new Cookie("name", "value"));
