I have a C# PSCmdlet class for implementing a PowerShell command and I want to get my module version while running the command.

I don't want to get the version from the assembly location because I need the actual version loaded (it can be different, for example, if I keep PowerShell open while upgrading my module, the assembly will point to the upgraded version and I won't get the one that already loaded).

I need something like Get-Module for the current session but from my C# command code.

How can I do it?

差不多一年后我一直在进行同样的十字军东征，这就是我想出的：

$version = Split-Path -Leaf $MyInvocation.MyCommand.ScriptBlock.Module.ModuleBase

根据我的评论详细说明。所以，在PowerShell中，也许是这样的......

# Put this in your profile (ISE/PowerShell/VSCode)
$AutomaticModules     = Get-Module

$AutomaticModules
# Results

所以，作为一个函数：

function Get-SessionModule
{
    Param
    (
        [String]$ModuleName
    )

    (Compare-Object -ReferenceObject (Get-Module) -DifferenceObject $AutomaticVModules -Property Name -PassThru |
    Where -Property Name -ne 'AutomaticVModules') -Match $ModuleName
}

Get-SessionModule -ModuleName IsePester
