Just to add a bit of value to this thread (I too was looking for a way to consume a RESTful service and easily provide credentials and came across this thread ... I did not have the "Date" requirement), Aaron Skonnard has written an excellent article on using the WCF REST Starter Kit called:
只是为了给这个线程增加一点价值（我也在寻找一种方法来使用 RESTful 服务并轻松提供凭据并遇到了这个线程......我没有“日期”要求），Aaron Skonnard 写道一篇关于使用 WCF REST Starter Kit 的优秀文章称为：
A Developer's Guide to the WCF REST Starter Kit
There is a very informative section on how to consume a RESTful service using HttpClient. And here's the code snippet to talk to Twitter:
关于如何使用 HttpClient 使用 RESTful 服务，有一个非常有用的部分。这是与 Twitter 对话的代码片段：
HttpClient http = new HttpClient("http://twitter.com/statuses/");
http.TransportSettings.Credentials =
new NetworkCredential("{username}", "{password}");
HttpResponseMessage resp = http.Get("friends_timeline.xml");
resp.EnsureStatusIsSuccessful();
ProcessStatuses(resp.Content.ReadAsStream());

Despite its somewhat misleading name, ADO.NET Data Services(which is part of .NET 3.5) contains APIs for both exposing and consuming REST-based services. In your case you can safely ignore the part that allows you to expose services and concentrate on the client part.
尽管名称有些误导，但ADO.NET 数据服务（它是 .NET 3.5 的一部分）包含用于公开和使用基于 REST 的服务的 API。在您的情况下，您可以安全地忽略允许您公开服务并专注于客户端部分的部分。
It supports LINQ and all sorts of goodness, allowing you to query your REST service like this:
它支持 LINQ 和各种优点，允许您像这样查询 REST 服务：
var selectedOrders = from o in context.Orders
where o.Freight > 30
orderby o.ShippedDate descending
select o;
There's more about it here. Give it a try - I've been pretty happy with it so far.
这里有更多关于它的信息。试一试 - 到目前为止，我对它非常满意。
