Inserting records into servicenow table using

I have a csv containing emp nos and date field. I want to iterate over the csv and insert those records into a service now table using Any pointers will be helpful.

public static void CreateRecordsinServiceNow(List<KeyValuePair<string, user_Record>> dt)
   String userID = "";
   string username = ConfigurationManager.AppSettings["ServiceNowUserName"];
   string password = ConfigurationManager.AppSettings["ServiceNowPassword"];
   string url = ConfigurationManager.AppSettings["ServiceNowUrl"];
   var auth = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes(username + ":" +    password));
       //iterate over List for records.. 
       Log("\r\n POST request started");

How do i proceed.
