string currentDirectory   Path GetDirectoryName Assembly GetEntryAssembly   Location   string archiveFolder   Path Combine currentDirectory   archive    string   files   Directory GetFiles archiveFolder     zip      The first parameter is the path  The second is the search pattern you want to use

Write it like this   string   files   Directory GetFiles     Archive      zip        is for relative to the folder where you started your exe  and   to allow   in the name   When using filters  you pass it as a second parameter  You can also add a third parameter to specify if you want to search recursively for the pattern   In order to get the folder where your  exe actually resides  use   var executingPath   Path GetDirectoryName Assembly GetEntryAssembly   Location

To make sure you have the application s path  and not just the current directory   use this      http   msdn microsoft com en-us library system diagnostics process getcurrentprocess aspx   Now you have a Process object that represents the process that is running   Then use Process MainModule FileName      http   msdn microsoft com en-us library system diagnostics processmodule filename aspx   Finally  use Path GetDirectoryName to get the folder containing the  exe      http   msdn microsoft com en-us library system io path getdirectoryname aspx   So this is what you want   string folder   Path GetDirectoryName Process GetCurrentProcess   MainModule FileName       Archive    string filter      zip   string   files   Directory GetFiles folder  filter      Notice that   Archive   from your question is now    Archive    you need the   so that the   backslashes aren t interpreted as the start of an escape sequence   Hope that helps

As others have said  you can should prepend the string with    though you could also just escape the backslashes   but what they glossed over  that is  didn t bring it up despite making a change related to it  was the fact that  as I recently discovered  using   at the beginning of a pathname  without   to represent the current directory  refers to the root of the current directory tree   C  foo bar gt cd   C   gt    versus  C  foo bar gt cd    C  foo bar gt     Using   by itself has the same effect as using    by itself  from my experience  I don t know if there are any specific cases where they somehow would not mean the same thing    You could also just leave off the leading      if you want   C  foo gt cd bar C  foo bar gt    In fact  if you really wanted to  you don t even need to use backslashes  Forwardslashes work perfectly well   Though a single   doesn t alias to the current drive root as   does    C   gt cd foo bar C  foo bar gt    You could even alternate them   C   gt cd foo bar baz C  foo bar baz gt       I ve really gone off-topic here  though  so feel free to ignore all this if you aren t interested
