C#: Get The Status Of Multiple Letters with GetLetterStatusMultiple()

Instructions

Create a new Console Application project and add a web reference

Copy the entire code below, delete anything written in your application and paste the code there
Replace "MyUsername" and "MyPassword" with your PostalMethods user details
Replace "ID1,ID2,ID3" with a comma separated list of LetterIDs for which you would like to get the status
Start your application. If the response is -3000, you will see the status report for each letter. If the response is any other number, check the Web Service Status Codes section.

    public void Main()
    {
                com.postalmethods.api.PostalWSSimple objPM = new com.postalmethods.api.PostalWSSimple();
        com.postalmethods.api.GetLetterStatus_MultipleResult objResult;
 
        //
        // Invoke the GetLetterStatus_Multiple method
        //
        objResult = objPM.GetLetterStatus_Multiple("MyUsername", "MyPassword", "ID1,ID2,ID3");
 
        //
        // Check response status
        //
        if (objResult.ResultCode == -3000)
        {
            //
            // -3000 means that the data was successfully retrieved.
            //
            foreach (com.postalmethods.api.LetterStatus status in objResult.LetterStatuses)
            {
                Console.WriteLine("ID: {0}", status.ID);

        else
        {
            //
            // A value less than -3000 means an error occured.
            // See the PostalMethods Status Codes: http://www.postalmethods.com/statuscodes.
            //
            Console.WriteLine("Error is:" + objResult.ResultCode);
