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

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" with the low LetterID of the range and "ID2" with the high LetterID of the range for which you would like to get the status
Start your application. If the response is -3000, you will see the status report. If the response is any other number, check the Web Service Status Codes section.

using System.IO;
 
class Module1

    public void Main()
    {
                com.postalmethods.api.PostalWSSimple objPM = new com.postalmethods.api.PostalWSSimple();
        com.postalmethods.api.GetLetterStatus_MultipleResult objResult;
 
        //
        // Invoke the GetLetterStatus_Range method
        //
        objResult = objPM.GetLetterStatus_Range("MyUsername", "MyPassword",  ID1, ID2);
 
        //
        // 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);
                Console.WriteLine("Last update time: {0}", status.LastUpdateTime);

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