Quick Start (Base64): Retrieving file attachments from tasks using the web service API

The following C# code example retrieves file attachments. Each file attachment is saved as a TXT file.
using System; 
using System.Collections; 
using System.ComponentModel; 
using System.Data; 
using System.IO ; 
 
namespace RetrieveTasks 
{ 
    class Class1 
    { 
        [STAThread] 
        static void Main(string[] args) 
        { 
            try 
            { 
                //Create a TaskManagerServiceService object and set authentication values 
                TaskManagerServiceService taskManager = new TaskManagerServiceService();  
                taskManager.Credentials = new System.Net.NetworkCredential("administrator", "password"); 
 
                //Retrieve file attachments associated with the task 
                Boolean myTrue = true; 
                Object[] fileAttachments = taskManager.getAttachmentListForTask(304,myTrue); 
             
                //Determine the number of returned tasks 
                int num = fileAttachments.Length; 
                 
                //Iterate through the Object array 
                for (int i=0; i<num;i++) 
                { 
                    //Extract the BLOB instance from the Object array 
                    BLOB fileAttachment = (BLOB)fileAttachments[i];     
 
                    //Populate a byte array with a BLOB data 
                    byte[] outByteArray=outDoc.binaryData;  
     
                    //Create a new file that represents the file attachment 
                    string FILE_NAME = "C:\\FileAtt" +i+".txt" ;  
                    FileStream fs2 = new FileStream(FILE_NAME, FileMode.OpenOrCreate); 
     
                    //Create a BinaryWriter object 
                    BinaryWriter w = new BinaryWriter(fs2); 
                    w.Write(outByteArray); 
                    w.Close(); 
                    fs2.Close(); 
                         
                } 
            } 
            catch (Exception ee) 
            { 
                Console.WriteLine(ee.Message); 
            } 
        }
