Passing [] in HttpRequestMessage query parameter

Question

I'm trying to pass a query parameter to a REST API. The parameter has [] characters in it, and I just cannot get it to work.

This is my code:

var request = new HttpRequestMessage();

request.RequestUri = new Uri("https://api.eu.itglue.com/organizations");
request.Method = HttpMethod.Get;

This works, but this doesn't:

var request = new HttpRequestMessage();

request.RequestUri = new Uri("https://api.eu.itglue.com/organizations?page[size]=1000");
request.Method = HttpMethod.Get;

What am I missing?

Thanks!

I believe square brackets have limitations in their URL usage, and you need to encode them to %5B and %5D, respectively. Like this:

request.RequestUri = new Uri("https://api.eu.itglue.com/organizations?page%5Bsize%5D=1000");

More Info: Are square brackets permitted in URLs?
