powershell: creating a generic hashset with syntax error? -


i tried in powershell 4.0:

[system.assembly]::loadwithpartialname("system.collections.generic") $m = new-object '[system.collections.generic::hashset](string)' $m.gettype()

but running gives error. usage incorrect? have 2 lines of code!

unable find type [system.assembly]. make sure assembly contains type loaded. @ d:\untitled1.ps1:1 char:1 + [system.assembly]::loadwithpartialname("system.collections.generic") + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + categoryinfo          : invalidoperation: (system.assembly:typename) [], runtimeexception + fullyqualifiederrorid : typenotfound  new-object : cannot find type [[system.collections.generic::hashset]                (string)]: verify assembly containing type loaded. @ d:\untitled1.ps1:2 char:6 + $m = new-object '[system.collections.generic::hashset](string)' +      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + categoryinfo          : invalidtype: (:) [new-object],         psargumentexception + fullyqualifiederrorid : typenotfound,microsoft.powershell.commands.newobjectcommand  cannot call method on null-valued expression. @ d:\untitled1.ps1:3 char:1 + $m.gettype() + ~~~~~~~~~~~~ + categoryinfo          : invalidoperation: (:) [], runtimeexception + fullyqualifiederrorid : invokemethodonnull

loadwithpartialname() in [system.reflection.assembly], not [system.assembly]. also, new-object syntax off.

[system.reflection.assembly]::loadwithpartialname("system.collections.generic") $m = new-object 'system.collections.generic.hashset[string]' $m.gettype()
