open file in same folder as application

Expand Post »

can anyone tell me if it is possible in C# to open a file which is located in the same folder as the application without specifying the path to that file?

if both file and program is located for example on C:/containfileandprog can i open the file from within a program without writing C:/containfileandprog but just the filename.dat?

i have no control on where the file or the program is going to be installed so i cant specify them in advance. but i can make sure that they both end up in the same folder where ever the enduser might want to put them.

Re: open file in same folder as application

to open a file that's beside your application

C# Syntax (Toggle Plain Text)

Application.StartupPath returns the path where your application starts from

Example to open text file called 1.txt which is beside your .exe

C# Syntax (Toggle Plain Text)
System.Diagnostics.Process.Start(Application.StartupPath + "\\1.txt");
System.Diagnostics.Process.Start(Application.StartupPath + "\\1.txt");

Re: open file in same folder as application

if you are doing console, it should work like this:

C# Syntax (Toggle Plain Text)
string _sAppPathName = Process.GetCurrentProcess().MainModule.FileName; 
 
string _sDataFilePath = _sAppPath.Substring(0, _sAppPath.Length - (_sAppPath.Length - _sAppPath.LastIndexOf(@"\"))) + @"\yourfilename.yourextension";
string _sAppPathName = Process.GetCurrentProcess().MainModule.FileName; 

string _sDataFilePath = _sAppPath.Substring(0, _sAppPath.Length - (_sAppPath.Length - _sAppPath.LastIndexOf(@"\"))) + @"\yourfilename.yourextension";
