Question

I need to use HTTP Post to send a a string array like so…

        Dim wc As New Net.WebClient
        Dim NC As New Specialized.NameValueCollection
        NC.Add("api_user", "some user")
        NC.Add("api_key", "some key")
        NC.Add("from", "[e-mail]")
        NC.Add("subject", "testing...")
        NC.Add("body", "testing...again")
        NC.Add("to", string_array)

i have tried several methods, but i keep getting – The remote server returned an error: (400) Bad Request.

I’m posting to SendGrid via their WebAPI

Just found a solution.

    For i = 0 To addresess.Length - 1
        NC.Add("to[" & i & "]", addresess(i))
    Next

use an index and the same keyName
