.NET, Linux and File Paths
Recently, I ran into a small problem while trying my Image Resize utility on Linux. I have written it using C# (.NET) and tested it on windows, everything works fine. On Linux (with Mono) it gave problems. Having programmed on windows, I have always assumed that file paths have this form
C:\MyFolder\Myfile.txt
So, this line of code works fine for Windows:
outpath = destdirname + @”" +newFileName;
But on Linux, it does not give desired output. In Unix/Linux, ‘/’ is used as directory separator and interestingly, ” can be part of a file name! So, what I did seems like a really bad coding practice. The best way to do this is:
outpath = destdirname + Path.DirectorySeparatorChar + newFileName;
There is a nice article on MSDN regarding this. So next time I write .NET code, I better remmember, it has to run on Linux also .
