一个WinForm程序，项目文件存放于D:\Projects\Demo，编译后的文件位于D:\Projects\Demo\bin\Debug，最后的结果如下：

1、System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName=D:\Projects\Demo\bin\Debug\Demo.vshost.exe
2、System.Environment.CurrentDirectory=D:\Projects\Demo\bin\Debug
3、System.IO.Directory.GetCurrentDirectory()=D:\Projects\Demo\bin\Debug
4、System.AppDomain.CurrentDomain.BaseDirectory=D:\Projects\Demo\bin\Debug\
5、System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase=D:\Projects\Demo\bin\Debug\
6、System.Windows.Forms.Application.StartupPath=D:\Projects\Demo\bin\Debug
7、System.Windows.Forms.Application.ExecutablePath=D:\Projects\Demo\bin\Debug\Demo.EXE

System.Environment.GetEnvironmentVariable("windir")=C:\WINDOWS
System.Environment.GetEnvironmentVariable("INCLUDE")=C:\Program Files\Microsoft Visual Studio.NET 2005\SDK\v2.0\include\
System.Environment.GetEnvironmentVariable("TMP")=C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp
System.Environment.GetEnvironmentVariable("TEMP")=C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp
System.Environment.GetEnvironmentVariable("Path")=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\Program Files\Microsoft SQL Server\90\Tools\binn\
