C#擷取項目程式路徑的方法

C#擷取項目程式路徑的方法                                                                                                                                                            
.asp.net webform用“Request.PhysicalApplicationPath擷取網站所在虛擬目錄的實體路徑，最後包含“\”；                                                                                  
                                                                                                                                                                                    
2.c# winform用                                                                                                                                                                      
A：“Application.StartupPath”:擷取當前應用程式所在目錄的路徑，最後不包含“\”；                                                                                                    
B：“Application.ExecutablePath ”:擷取當前應用程式檔案的路徑，包含檔案的名稱；                                                                                                     
C：“AppDomain.CurrentDomain.BaseDirectory”:擷取當前應用程式所在目錄的路徑，最後包含“\”；                                                                                        
D：“System.Threading.Thread.GetDomain().BaseDirectory”:擷取當前應用程式所在目錄的路徑，最後包含“\”；                                                                            
E：“Environment.CurrentDirectory”:擷取當前應用程式的路徑，最後不包含“\”；                                                                                                       
F：“System.IO.Directory.GetCurrentDirectory”:擷取當前應用程式的路徑，最後不包含“\”；                                                                                            
                                                                                                                                                                                    
3.c# windows service用“AppDomain.CurrentDomain.BaseDirectory”或 “System.Threading.Thread.GetDomain().BaseDirectory”；                                                           
用“Environment.CurrentDirectory”和 “System.IO.Directory.GetCurrentDirectory”將得到“ system32”目錄的路徑；                                                                     
如果要使用“Application.StartupPath”或“Application.ExecutablePath ”，需要手動添加對“System.Windows.Forms.dll ”的引用，並在程式開頭用“using   System.Windows.Forms”聲明該引用；
                                                                                                                                                                                    
4.在卸載程式擷取系統安裝的目錄：                                                                                                                                                    
System.Reflection.Assembly curPath = System.Reflection.Assembly.GetExecutingAssembly();                                                                                    
string path=curPath.Location;//得到安裝程式類SetupLibrary檔案的路徑，擷取這個檔案路徑所在的目錄即得到安裝程式的目錄
