Windows Mobile发送短信应用分为两种，一是调用Windows Mobile自有的发送短信窗口，将接收用户的手机号码传递给该窗口，完成短信发送（暂且称为窗口短信），另一种是通过调用API将文本发送给指定的号码，这中发送方式对于用户是无感知的（暂且称为无感知短信，下面对这两种方式的实现分别介绍。窗口短信：窗口短信实现比较简单，可以直接使用下面的启动参数启动系统的EXE文件即可， System.Diagnostics.Process.Start("tmail.exe", "-transport /"SMS/" -to /"" + 手机号码 + "/" -body /"短信内容/"");但要注意的是，在发送完毕后，短信列表页面会在你关闭发送信息窗口后呈现出来，可以在页面的关闭事件中，使用FindWind方法，找到系统的【短信】窗口，将其关闭即可。无感知短信1.Windows Mobile 5.0及以上版本无感知短信接口与Mobile操作系统的版本有关，如果是基于Windows Mobile5.0 的设备 ，完成短信发送比较容易，因为微软已经给你封装好了底层的API，可以直接进行调用，引用Microsoft.WindowsMobile.PocketOutlook.dll后，使用SmsMessage smsSend = new SmsMessage(phone, sms);smsSend.Send();方法便可以完成对一条短息的发送。2.Windows Mobile 2003或Windows Mobile2003SE设备在5.0以前的版本，虽然现在使用量比较小了，但是在2年前，在其上面发送短息可以说很是费劲，当时确实还让我头疼了一段时间，需要用户自己封装底层的API，然后进行调用，我这里有一个，贴出来，以供大家参考using System;using System.Runtime.InteropServices;using System.Text;namespace SmartSMS{ /// <summary> /// 短信发送程序 /// </summary> public class SMS { public SMS() { // // TODO: 在此处添加构造函数逻辑 // } private const string SMS_MSGTYPE_TEXT = "Microsoft Text SMS Protocol"; private const int SMS_MODE_SEND = 2; // Open in send mode private const int SMSDE_GSM = 2; // Use standard GSM encoding private const int SMSAT_INTERNATIONAL = 1; // International number format private const int PS_MESSAGE_OPTION_NONE = 0; // No message options private const int PS_MESSAGE_CLASS0 = 0; // Show but do not store private const int PS_MESSAGE_CLASS1 = 1; // Store and show private const int PSRO_NONE = 0; // No replacements private const int SMS_OPTION_DELIVERY_NONE = 0; // No delivery options private const int SMS_MAX_ADDRESS_LENGTH = 256; // Max length of address [DllImport("sms.dll")] private static extern int SmsOpen( string ptsMessageProtocol, int dwMessageModes, ref IntPtr psmshHandle, int phMessageAvailableEvent); [DllImport("sms.dll")] private static extern int SmsSendMessage( IntPtr smshHandle, int psmsaSMSCAddress, IntPtr psmsaDestinationAddress, int pstValidityPeriod, IntPtr pbData, int dwDataSize, IntPtr pbProviderSpecificData, int dwProviderSpecificDataSize, int smsdeDataEncoding, int dwOptions, int psmsmidMessageID); [DllImport("sms.dll")] private static extern int SmsClose(IntPtr smshHandle); [DllImport("coredll.dll")] private static extern IntPtr LocalAlloc(uint uFlags, uint uBytes); [DllImport("coredll.dll")] internal static extern IntPtr LocalFree(IntPtr hMem); private static IntPtr AllocHGlobal(IntPtr cb) { IntPtr hmem; hmem = LocalAlloc(0x40, (uint) cb); return hmem; } private static void FreeHGlobal(IntPtr hglobal) { LocalFree(hglobal); } public static int SendSMS(string Number, string Message) { int returnValue = 0; IntPtr smsHandle = new IntPtr(0); // Set address structure byte[] smsatAddressType = BitConverter.GetBytes(SMSAT_INTERNATIONAL); byte[] ptsAddress = Encoding.Unicode.GetBytes(Number); byte[] smsAddressTag = new byte[smsatAddressType.Length + ptsAddress.Length]; Array.Copy(smsatAddressType, 0, smsAddressTag, 0, smsatAddressType.Length); Array.Copy(ptsAddress, 0, smsAddressTag, smsatAddressType.Length, ptsAddress.Length); IntPtr smsAddress = AllocHGlobal((IntPtr)smsAddressTag.Length); Marshal.Copy(smsAddressTag, 0, smsAddress, smsAddressTag.Length); // Set provider data structure byte[] dwMessageOptions = BitConverter.GetBytes(PS_MESSAGE_OPTION_NONE); byte[] psMessageClass = BitConverter.GetBytes(PS_MESSAGE_CLASS1); byte[] psReplaceOption = BitConverter.GetBytes(PSRO_NONE); byte[] smsProviderDataTag = new byte[dwMessageOptions.Length + psMessageClass.Length + psReplaceOption.Length]; Array.Copy(dwMessageOptions, 0, smsProviderDataTag, 0, dwMessageOptions.Length); Array.Copy(psMessageClass, 0, smsProviderDataTag, dwMessageOptions.Length, psMessageClass.Length); Array.Copy(psReplaceOption, 0, smsProviderDataTag, dwMessageOptions.Length + psMessageClass.Length, psReplaceOption.Length); IntPtr smsProviderData = AllocHGlobal((IntPtr) smsProviderDataTag.Length); Marshal.Copy(smsProviderDataTag, 0, smsProviderData, smsProviderDataTag.Length); // Set message// Encoding unicode = Encoding.Unicode;// Encoding utf8 = Encoding.ASCII;// byte[] smsMessageTag1 = Encoding.ASCII.GetBytes(Message);// byte[] smsMessageTag = Encoding.Convert(utf8,unicode,smsMessageTag1); byte[] smsMessageTag = Encoding.Unicode .GetBytes(Message); IntPtr smsMessage = AllocHGlobal((IntPtr)smsMessageTag.Length); Marshal.Copy(smsMessageTag, 0, smsMessage, smsMessageTag.Length); // Get handle if (0 != SmsOpen(SMS_MSGTYPE_TEXT, SMS_MODE_SEND, ref smsHandle, 0)) returnValue = -1; // Could not open // Send message if (0 != SmsSendMessage(smsHandle, 0, smsAddress, 0, smsMessage, smsMessageTag.Length, smsProviderData, smsProviderDataTag.Length, SMSDE_GSM, SMS_OPTION_DELIVERY_NONE, 0)) returnValue = -2; FreeHGlobal(smsMessage); FreeHGlobal(smsProviderData); FreeHGlobal(smsAddress); // Release handle if (0 != SmsClose(smsHandle)) returnValue = -3; // Could not close return returnValue; } }}
