Tag: How do you pass multiple query parameters?

You have multiple options for passing multiple parameters to a GET method: FromRouteAttribute, FromQuery and Model Binding.

The value for the corresponding parameter is given after the symbol “equals” (=). Multiple parameters can be passed through the URL by separating them with multiple “&” .

id=123 would be a query string. It seems to be a frequently asked question in Stack Overflow. It turns out, apparently, that there’s no standard for how parameters that can have multiple values should behave in HTTP .
