How do I pass the KeyValuePair into this method?

Question

How do I pass the KeyValuePair into this method, accepting ICollection<KeyValuePair<string, string>>?

If my header name is 'auth' and the header value is 'local'

_restActions.ExecutePostRequest(resource, body, {WHAT GOES HERE});

Answer 1

You can pass a Dictionary<string, string> which implements ICollection<KeyValuePair<string, string>> and, I would argue, allows the most concise instantiation syntax:

_restActions.ExecutePostRequest(
    resource, 
    body, 
    new Dictionary<string, string>{{"one", "two"}, {"foo", "bar"}});

Answer 2

You do not need to pass anything since there is null on headers parameter (default value). If you do want to pass something then it would be anything like new List<KeyValuePair<string, string>> { new KeyValuePair<string, string>("content-type", "text/plain") }
