用代码实现文本朗读

using System.Speech.Synthesis;

SpeechSynthesizer sSpeechSynthesizer  = new SpeechSynthesizer();

sSpeechSynthesizer .Speak("化肥会挥发！！！");

注：xp不支持中文

如何获取程序当前目录
System.IO.Path.GetDirectoryName(Application.ExecutablePath) ;

1.c#中得到相对路径
(new FileInfo(Assembly.GetExecutingAssembly().Location.ToString())).DirectoryName;
2.c#得到当前运行cad文件保存路径
Application.GetSystemVariable("DwgPrefix").ToString();
3.c#得到cad可搜索路径中某一文件的全路径
HostApplicationServices.Current.FindFile("LandUse.mdb", Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database, FindFileHint.Default);
4.c#获取当前运行AutoCAD的路径
Process.GetCurrentProcess().MainModule.FileName;
