Useful Static .NET Methods

by Feb 9, 2015

All Versions

PowerShell can access static methods of .NET types. Here are some real world one-liners that can do a lot for you:


[Convert]::ToString(576255753217, 8)




[IO.Path]::ChangeExtension('c:\test.txt', 'bak') 

To find out more, delete the code after the type (the text in square brackets), then add two colons. PowerShell ISE will automatically pop up tab completion and show you the methods found in that type. In the PowerShell console, simply press TAB to get completion suggestions.

You can also pipe a type to Get-Member:

PS> [Math] | Get-Member -MemberType *Method -Static

And to see the signature(s) of a method, omit the parenthesis:

PS> Get-Something -Path test
You entered test.

PS> [Math]::Round 

static double Round(double a
static double Round(double value, int digits)
static double Round(double value, System.MidpointRounding mode)
static double Round(double value, int digits, System.MidpointRounding mode
static decimal Round(decimal d
static decimal Round(decimal d, int decimals)
static decimal Round(decimal d, System.MidpointRounding mode)
static decimal Round(decimal d, int decimals, System.MidpointRounding mode)
