Remarks

The MailChimpCommand class provides the following methods for executing commands against Mailchimp:

Item	Description
ExecuteReader	Executes commands that return rows.
Devart.Common.DbCommandBase.ExecutePageReader	Returns a specific subset of rows when paging through the results of a query.
ExecuteNonQuery	Executes SQL commands such as INSERT, DELETE, UPDATE.
ExecuteScalar	Retrieves a single value (for example, an aggregate value) from a data source.

If execution of the command results in a fatal MailChimpException, the MailChimpConnection may close. However, the user can reopen the connection and continue.

Example

The following example uses the ExecuteReader method of MailChimpCommand, along with MailChimpDataReader and MailChimpConnection, to select rows from a table.

csharp

public void ReadMyData(string myConnString)
{
  string mySelectQuery = "SELECT Id, Name FROM Folders";
  MailChimpConnection mailchimpConnection = new MailChimpConnection(myConnString);
  MailChimpCommand mailchimpCommand = new MailChimpCommand(mySelectQuery,mailchimpConnection);
  mailchimpConnection.Open();
  MailChimpDataReader mailchimpReader = mailchimpCommand.ExecuteReader();
  try
  {
    while (mailchimpReader.Read())
    {
      Console.WriteLine(mailchimpReader.GetInt32(0).ToString() + ", " + mailchimpReader.GetString(1));
    }
  }
  finally
  {
  // always call Close when done reading.
  mailchimpReader.Close();
  // always call Close when done reading.
  mailchimpConnection.Close();
  }
}

Visual Basic

  Dim mySelectQuery As String = "SELECT Id, Name FROM Folders"
  Dim mailchimpConnection As New MailChimpConnection(myConnString)

  Finally
      ' always call Close when done reading.
