C#获取项目程序路径的方法

C#获取项目程序路径的方法                                                                                                                                                            
.asp.net webform用“Request.PhysicalApplicationPath获取站点所在虚拟目录的物理路径，最后包含“\”；                                                                                  
                                                                                                                                                                                    
2.c# winform用                                                                                                                                                                      
A：“Application.StartupPath”:获取当前应用程序所在目录的路径，最后不包含“\”；                                                                                                    
B：“Application.ExecutablePath ”:获取当前应用程序文件的路径，包含文件的名称；                                                                                                     
C：“AppDomain.CurrentDomain.BaseDirectory”:获取当前应用程序所在目录的路径，最后包含“\”；                                                                                        
D：“System.Threading.Thread.GetDomain().BaseDirectory”:获取当前应用程序所在目录的路径，最后包含“\”；                                                                            
E：“Environment.CurrentDirectory”:获取当前应用程序的路径，最后不包含“\”；                                                                                                       
F：“System.IO.Directory.GetCurrentDirectory”:获取当前应用程序的路径，最后不包含“\”；                                                                                            
                                                                                                                                                                                    
3.c# windows service用“AppDomain.CurrentDomain.BaseDirectory”或 “System.Threading.Thread.GetDomain().BaseDirectory”；                                                           
用“Environment.CurrentDirectory”和 “System.IO.Directory.GetCurrentDirectory”将得到“ system32”目录的路径；                                                                     
如果要使用“Application.StartupPath”或“Application.ExecutablePath ”，需要手动添加对“System.Windows.Forms.dll ”的引用，并在程序开头用“using   System.Windows.Forms”声明该引用；
                                                                                                                                                                                    
4.在卸载程序获取系统安装的目录：                                                                                                                                                    
System.Reflection.Assembly curPath = System.Reflection.Assembly.GetExecutingAssembly();                                                                                    
string path=curPath.Location;//得到安装程序类SetupLibrary文件的路径，获取这个文件路径所在的目录即得到安装程序的目录
