Enviar e-mail para o Windows Mobile em C# sem utilizar o PocketOutlook

Question

Pessoal tenho uma aplicação de Windows Mobile, preciso cirar uma rotina que faça essa aplicação enviar e-mail mas sem utilizar o Pocket Outlook , estou tentando utilizar classe MAPI , esse é o codigo que estou usando :

 

using System;

using System.Runtime.InteropServices;

using System.IO;

using System.Collections.Generic;

using System.Windows.Forms;

namespace Mapi

{

public class MAPI

{

public bool AddRecipientTo(string email)

{

return AddRecipient(email, HowTo.MAPI_TO);

}

public int SendMailPopup(string strSubject, string strBody)

{

return SendMail(strSubject, strBody, MAPI_LOGON_UI | MAPI_DIALOG);

}

public int SendMailDirect(string strSubject, string strBody)

{

return SendMail(strSubject, strBody, MAPI_LOGON_UI);

}

 

[DllImport("C:\\WINDOWS\\system32\\Mapi32.dll")]

static extern int MAPISendMail(IntPtr sess, IntPtr hwnd,

MapiMessage message, int flg, int rsv);

int SendMail(string strSubject, string strBody, int how)

{

MapiMessage msg = new MapiMessage();

msg.subject = strSubject;

msg.noteText = strBody;

msg.recips = GetRecipients(out msg.recipCount);

m_lastError = MAPISendMail(new IntPtr(0), new IntPtr(0), msg, how, (0));

if (m_lastError > 1)

MessageBox.Show(" MAPISendMail failed! " + GetLastError(), " MAPISendMail");

Cleanup(ref msg);

return m_lastError;

}

bool AddRecipient(string email, HowTo howTo)

{

MapiRecipDesc recipient = new MapiRecipDesc();

recipient.recipClass = (int)howTo;

recipient.name = email;

m_recipients.Add(recipient);

return true;

}

IntPtr GetRecipients(out int recipCount)

{

recipCount = 0;

if (m_recipients.Count == 0)

return IntPtr.Zero;

int size = Marshal.SizeOf(typeof(MapiRecipDesc));

IntPtr intPtr = Marshal.AllocHGlobal(m_recipients.Count * size);

int ptr = (int)intPtr;

foreach (MapiRecipDesc mapiDesc in m_recipients)

{

Marshal.StructureToPtr(mapiDesc, (IntPtr)ptr, false);

ptr += size;

}

recipCount = m_recipients.Count;

return intPtr;

}

void Cleanup(ref MapiMessage msg)

{

int size = Marshal.SizeOf(typeof(MapiRecipDesc));

int ptr = 0;

if (msg.recips != IntPtr.Zero)

{

ptr = (int)msg.recips;

for (int i = 0; i < msg.recipCount; i++)

{

Marshal.DestroyStructure((IntPtr)ptr, typeof(MapiRecipDesc));

ptr += size;

}

Marshal.FreeHGlobal(msg.recips);

}

m_recipients.Clear();

m_lastError = 0;

}

public string GetLastError()

{

if (m_lastError <= 26)

return errors[m_lastError];

return " MAPI error [" + m_lastError.ToString() + " ]";

}

public readonly string[] errors = new string[]

{

" OK [0]" , " User abort [1]" , " General MAPI failure [2]" ,

" MAPI login failure [3]" , " Disk full [4]" ,

" Insufficient memory [5]" , " Access denied " ,

" -unknown- [7]" , " Too many sessions " ,

" Too many files were specified [9]" ,

" Too many recipients were specified [10]" ,

" A specified attachment was not found [11]" ,

" Attachment open failure [12]" ,

" Attachment write failure [13]" , " Unknown recipient [14]" ,

" Bad recipient type [15]" , " No messages [16]" ,

" Invalid message [17]" , " Text too large [18]" ,

" Invalid session [19]" , " Type not supported [20]" ,

" A recipient was specified ambiguously [21]" ,

" Message in use [22]" , " Network failure [23]" ,

" Invalid edit fields [24]" , " Invalid recipients [25]" ,

" Not supported [26]"

};

 

List<MapiRecipDesc> m_recipients = new List<MapiRecipDesc>();

int m_lastError = 0;

const int MAPI_LOGON_UI = 0x00000001;

const int MAPI_DIALOG = 0x00000008;

enum HowTo { MAPI_ORIG = 0, MAPI_TO };

}

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]

public class MapiMessage

{

public int reserved;

public string subject;

public string noteText;

public string messageType;

public string dateReceived;

public string conversationID;

public int flags;

public IntPtr originator;

public int recipCount;

public IntPtr recips;

public int fileCount;

public IntPtr files;

}

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]

public class MapiRecipDesc

{

public int reserved;

public int recipClass;

public string name;

public string address;

public int IDSize;

public IntPtr entryID;

}

}

 

esse é o evento do botão :

private void Enviar_Click(object sender, EventArgs e)

{

MAPI mapi = new MAPI();

mapi.AddRecipientTo( "[e-mail] " );

mapi.SendMailDirect( " Teste" , " E-mail de Teste" );

}

 

Aparece a seguinte mensagem de erro :

_emptyArray = Cannot fetch the value of field '_emptyArray' because information about the containing class is unavailable.

 

Esse erro aparece quando faço:

List<MapiRecipDesc> m_recipients = new List<MapiRecipDesc>();

 

Se alguem poder me ajudar , ou sober algum outro modo de fazer isso.

Obrigado .
