How to create an array in a JSON query with C#

Hello all,

This request is refering to an existing request, which works great, but i have one small addition. In the above solution, there is only one option, but now i have more like:

"options": [
{
"key": "DOOR"
},
{
"key": "REFERENCE",
"input": "TEST JEROEN"
}
],

Select allOpen in new window

In the above solution one option is made with the following code:

     options = new[] { new { key = "DOOR" } },
                   

Select allOpen in new window

My question is, how can i make the orther(s). When i try this i get an error that my array is not correct. I tried something like:

   options = new object[] { 
                            new { key = "DOOR" }, 
                            new { key = "REFERENCE"}, 
                            new {input = dhlLabelRequest.orderReference.ToString() }

Select allOpen in new window

But this didn't work.

Thanks in advance.
