我正在写一个方法,比方说,1,你好,应该返回http://something.com/?something=1\u0026amp;hello=en.
我可以很容易地将它们组合在一起,但ASP.NET 3.5为构建URI提供了哪些抽象功能？我喜欢这样的东西：
URI uri = new URI("~/Hello.aspx"); // E.g. ResolveUrl is used here
uri.QueryString.Set("something","1");
uri.QueryString.Set("hello","en");
return uri.ToString(); // /Hello.aspx?something=1&hello=en
我发现Uri类听起来非常相关,但我找不到任何真正完成上述操作的内容.有任何想法吗？
(对于它的价值,参数的顺序对我来说无关紧要.)
解决方法
编辑纠正大量错误的代码
基于this answer到类似的问题,您可以轻松地执行以下操作：
UriBuilder ub = new UriBuilder();
// You might want to take more care here,and set the host,scheme and port too
ub.Path = ResolveUrl("~/hello.aspx"); // Assumes we're on a page or control.
// Using var gets around internal nature of HttpValueCollection
var coll = HttpUtility.ParseQueryString(string.Empty);
coll["something"] = "1";
coll["hello"] = "en";
ub.Query = coll.ToString();
return ub.ToString();
// This returned the following on the VS development server:
// http://localhost/Hello.aspx?something=1&hello=en
这也将对集合进行urlencode,因此：
coll["Something"] = "1"; coll["hello"] = "en&that";
将输出：
Something=1&hello=en%26that
