c# - Show certain HTML based off query string -

i have query string i'd pass razor view. example.com/25?type=1&assigned=1

i want change html based on if query string contains values. tried doing

@if (request.querystring["type=1&assigned=1"]) {   <button id="type1" class="btn-t btn-success type-button"  onclick="settype(1);"><i class="fa fa-info-circle fa-fw"></i>invitation</button> } else { <button id="type1" class="btn-t btn-xxxx  type-button" onclick="settype(1);"><i class="fa fa-info-circle fa-fw">  </i>invitation</button> } 

but displayed else. doing wrong?

request.querystring not boolean value, don't understand donig. namevaluecollection type. if still want check should write this:

@if (request.querystring["type"] == "1"     && request.querystring["assigned"] == "1") { ... } 

but it's bad practice manipulate querystring in mvc. use strongly typed views , don't mess request itself.
