i have class follows, api must in format

public class command {     public string response_type { get; set; }     public string text { get; set; }     public attachment[] attachments { get; set; } = new attachment[] { new attachment { } }; }  public class attachment {     public string title { get; set; }     public string title_link { get; set; }     public string image_url { get; set; } } 

so response_type, text , array of attachments. can see create attachment array , create empty object.

when creating object there ever 1 element in array.

how set or add array when declaring object, given object created in constructor

command result = new command() {     text = "rebooting!",     attachments[0] = ???? }; 

im missing simple, tried lots of combos

to add array need after construction

command result = new command() {     text = "rebooting!", };  result.attachments = new attachment[2] { result.attachments[0], new attachment() }; 

if want set value (since array created , contains 1 instance can

result.attachments[0] = new attachment();
