c# - Opening an explorer window with designated file selected -

i have application has option show selected file in folder in file resides. question is, how achieve this?

to clarify, if user in program selected "test.txt" file, want windows explorer window pop , highlight file user selected. can see similar behavior in limewire , utorrent. if select file in either of programs , choose "show in folder", pops windows explorer window file highlighted , selected. trying duplicate behavior.

i tried using following line:

system.diagnostics.process.start("explorer"); 

this popup windows explorer window, however, seems open default in "my documents" folder.

here go,

string filetoselect = @"c:\temp.img"; string args = string.format("/select, \"{0}\"", filetoselect);  processstartinfo pfi = new processstartinfo("explorer.exe", args); system.diagnostics.process.start(pfi); 

note: adding \" before , after {0} parameter enables filetoselect string contain spaces (i.e. "c:\my documents").

from thread:
programmatically select multiple files in windows explorer
