Splitting Paths C#

C# 3.0	
	var a = System.IO.Path.GetDirectoryName("foo\\bar\\beer")
	var b = System.IO.Path.GetFileName("foo\\bar\\beer")		
	

Python or IronPython	
	a , b = os.path.split ("foo\\bar\\beer" )		


PowerShell 2.0	$a = split-path "\foo\bar\beer"
	$b = split-path "\foo\bar\beer" -leaf

Joining Paths

C# 3.0	
	System.IO.Path.Combine("foo\\bar" , "beer" )		

Python or IronPython	
	os.path.join( "foo\\bar" , "beer" )		

PowerShell
	join-path "foo\bar" "beer"		

Path Exists?

C#
	System.IO.Directory.Exists("d:\\foo")
	System.IO.File.Exists("d:\\foo.txt"))


Python	
	os.path.exists( "d:\\foo.txt" )


PowerShell
    test-path "d:\foo.txt"

Get Full path

C#	
	System.IO.Path.GetFullPath("foo.txt")	

Python
	os.path.abspath( "foo.txt" )		

PowerShell
	[IO.Path]::GetFullPath("foo.txt")		

Normalize Paths

C#

Python


PowerShell
	$d = resolve-path "D:\foo\..\bar\beer"		

Create a Directory

Python

PowerShell
	New-Item -Path d:\folder -ItemType Directory		

Delete Folder and Contents Recursively
