How to create a campaign in MailChimp using ASP.Net

Question

I need to create and send campaigns right away MailChimp.com. For this purpose I used . C# wrapper Percepective MCAPI.dll

from the MailChimp API , it’s clear that we cannot write off, but we can create campaigns. I tried the code, but campaignID is retured null; No exception is thrown at least. I have installed campaigntype to Auto.

here is my code snippet:

try
{
     string apiKey = "api-us2"; // API KEY is valid
     string emailAddress = " [e-mail] ";
     listsForEmailInput lstForEmailInput = new listsForEmailInput (apiKey, emailAddress);
     listsForEmail cmd = new listsForEmail (lstForEmailInput);
     listsForEmailOutput lstEmailOutPut = cmd.Execute ();

     List lstResults = lstEmailOutPut.result;
     string listID = lstResults [0]; // Got Precraeted List ID (Valid Confirmed)

     Console.WriteLine ("\ n" + listID);                


     // compaign Create
     campaignCreateOptions campaignCreateOpt = new campaignCreateOptions ();
     campaignCreateOpt.list_id = listID;
     campaignCreateOpt.subject = "New Campaign from dev_Anil";
     campaignCreateOpt.from_email = " [e-mail] ";
     campaignCreateOpt.from_name = "anil";

     Dictionary content = new Dictionary ();
     content.Add ("html", "Helloaasdsa");
     content.Add ("text", "Hi all !! this is dev_anil");
     content.Add ("url", "");
     content.Add ("archive", "");

     campaignSegmentOptions csOptions = new campaignSegmentOptions ();
     csOptions.match = "any"; // Could not set Condition - need help for this

     // Need to set a Dictionary typeOptions because null is not supported
     Dictionary typeOptions = new Dictionary ();

     campaignCreateParms campaignCreateParms = new campaignCreateParms (apiKey, EnumValues.campaign_type.auto, campaignCreateOpt, content, csOptions, typeOptions);
     campaignCreateInput campaignCreateInput = new campaignCreateInput (campaignCreateParms);
     campaignCreate campaignCreate = new campaignCreate (campaignCreateInput);
     campaignCreateOutput ccOutput = campaignCreate.Execute (campaignCreateInput);
     string abc = ccOutput.result; // This comes out to null

}
 catch (Exception ee)
{
     Console.WriteLine ("\ n \ n Exception:" + ee.Message); // no exception
}

Can someone show me the right direction and what is wrong with the code.

any help would be greatly appreciated.

thank.

I solved this problem and here is the code as a solution. here listID is the requested list identifier in your account in Mailchimp.

private void CreateCampaignAndSend (string apiKey, string listID)
{
            Int32 TemplateID = 100;
            string campaignID = string.Empty;

        // compaign Create Options
        campaignCreateOptions campaignCreateOpt = new campaignCreateOptions();
        campaignCreateOpt.list_id = listID;
        campaignCreateOpt.subject = "subject";
        campaignCreateOpt.from_email = "[e-mail]";
        campaignCreateOpt.from_name = "abc";
        campaignCreateOpt.template_id = TemplateID;

        // Content

        Dictionary<string, string> content = new Dictionary<string, string>();
        content.Add("html_ArticleTitle1", "ArticleTitle1");
        content.Add("html_ArticleTitle2","ArticleTitle2");
        content.Add("html_ArticleTitle3", "ArticleTitle3");
        content.Add("html_Article1", "Article1");
        content.Add("html_Article2", "Article2");

        // Conditions
        List<campaignSegmentCondition> csCondition = new List<campaignSegmentCondition>();
        campaignSegmentCondition csC = new campaignSegmentCondition();

        csC.field = "interests-" + 123; // where 123 is the Grouping Id from listInterestGroupings()
        csC.op = "all";
        csC.value = "";
        csCondition.Add(csC);

        // Options
        campaignSegmentOptions csOptions = new campaignSegmentOptions();
        csOptions.match = "all";  



        // Type Options
        Dictionary<string, string> typeOptions = new Dictionary<string, string>();
        typeOptions.Add("offset-units", "days");
        typeOptions.Add("offset-time", "0");
        typeOptions.Add("offset-dir", "after");

        // Create Campaigns

        campaignCreate campaignCreate = new campaignCreate(new campaignCreateInput(apiKey, EnumValues.campaign_type.plaintext, campaignCreateOpt, content, csOptions, typeOptions));
        campaignCreateOutput ccOutput = campaignCreate.Execute();

        List<Api_Error> error = ccOutput.api_ErrorMessages;  // Catching API Errors


        if (error.Count <= 0)
        {
            campaignID = ccOutput.result;

        }
        else
        {
            foreach (Api_Error ae in error)
            {
                Console.WriteLine("\n ERROR Creating Campaign : ERRORCODE\t:" + ae.code + "\t ERROR\t:" + ae.error);

            }
        }

    }

I removed the url and archive from the content. Then the campaign was created just fine:

       // campaign Create
        campaignCreateOptions campaignCreateOpt = new campaignCreateOptions();
        campaignCreateOpt.list_id = listId;
        campaignCreateOpt.subject = " New Campaign from Someemone";
        campaignCreateOpt.from_email = "[e-mail]";
        campaignCreateOpt.from_name = "someone";


        Dictionary<string, string> content = new Dictionary<string, string>();
        content.Add("html", "Lots of cool stuff here.");


        campaignSegmentOptions csOptions = new campaignSegmentOptions();
        csOptions.match = "any";  // Could not set Condition -- need help for this

        // Need to set a Dictionary typeOptions because null is not supported
        Dictionary<string,string> typeOptions = new Dictionary<string, string>();

        campaignCreateParms campaignCreateParms = new campaignCreateParms(apiKey, EnumValues.campaign_type.trans, campaignCreateOpt, content, csOptions, typeOptions);
        campaignCreateInput campaignCreateInput = new campaignCreateInput(campaignCreateParms);
        campaignCreate campaignCreate = new campaignCreate(campaignCreateInput);
        campaignCreateOutput ccOutput = campaignCreate.Execute(campaignCreateInput);
        string newCampaignId = ccOutput.result;   // Not null anymore
