How to remove all parameters' values from query

I have a number of query strings looks like View.aspx?type=a&boo=bar&i=1

How to remove all parameters' values so it would become View.aspx?type=&boo=&i=

For each string set of parameters there is it's own combination of parameters, 2-3 in num开发者_JAVA技巧ber.

Edit: How to remove all parameters except specific set?

For all parameters

Regex.Replace(source, "=.+?(&|$)", "=$1")

To skip parameters "archive" and "boo":

Regex.Replace(source, "(?<![?&]archive|[?&]boo)=.+?(&|$)", "=$1",
    RegexOptions.IgnoreCase)

You want to do this inside that page? Why not forward the page to itself without parameters? Maybe I am missing the point. Care to explain a little more?

Use System.Uri, or System.UriBuilder
