Get-Random
cmdlet gets a randomly selected number. If you submit a collection of objects toGet-Random
, it gets one or more randomly selected objects from the collection.Get-Random
command returns a randomly selected 32-bit unsignedinteger between 0 (zero) and Int32.MaxValue (0x7FFFFFFF
, 2,147,483,647

Get-Random
gets randomly selected objects in random order fromthe collection up to the number specified by Count. Enter the objects, a variable that containsthe objects, or a command or expression that gets the objects. You can also pipe a collection ofobjects to Get-Random
.$null
. The array can be sent down the pipeline or as an InputObject parameter value.Type: | Object[] |
Position: | 0 |
Default value: | None |
Accept pipeline input: | True (ByValue) |
Accept wildcard characters: | False |
Get-Random
returns a value that is less than themaximum (not equal). Enter an integer, a double-precision floating-point number, or an object thatcan be converted to an integer or double, such as a numeric string ('100').Get-Random

uses theRandomNumberGenerator()method to generate a seed value. Because SetSeed results in non-random behavior, it's typicallyused only when trying to reproduce behavior, such as when debugging or analyzing a script thatincludes Get-Random
commands.Type: | Int32 |

supports 64-bit integers. In Windows PowerShell2.0, all values are cast to System.Int32.$null
. In earlier PowerShellversions, only the Maximum parameter in the RandomNumberParameterSet parameter set acceptedan empty string or $null
