我假设这里的returnUrl编码错误，在实际代码中是url编码的；在这种情况下，您需要第二次解析返回的url参数，但是-类似于：

var uri = new Uri("http://localhost:3000/Login/SignIn?timeout=5000&returnUrl=%2FHome.ashx%3Fparam1%3D555%26param2%3D666");
var query = HttpUtility.ParseQueryString(uri.Query);
foreach (string key in query.Keys)
{
Console.WriteLine($"{key}={query[key]}");
}
// further-decode returnUrl values
uri = new Uri(uri, query["returnUrl"]);
query = HttpUtility.ParseQueryString(uri.Query);
foreach (string key in query.Keys)
{
Console.WriteLine($"{key}={query[key]}");
}

输出：

timeout=5000
returnUrl=/Home.ashx?param1=555&param2=666
param1=555
param2=666
