$MyInvocation.MyCommand.Name 将 ps1 转换为 exe 后返回空值

Question

powershell script results in incorrect output after converting it to an .exe-file and executing it:

$MyScriptName = $MyInvocation.MyCommand.Name

Above is snippet of my powershell code, which works fine and saves the script name in the $MyScriptName variable.

Once we convert the .ps1-script to an .exe-file and execute it, the variable $MyScriptName has a null value.

Answer 1

Script related variables become unavailable after converting the script to an executable file. You can find information about it here on Markus Scholtes' release page on Github for the PS2EXE-GUI version (Win-PS2EXE): PS2EXE-GUI

Here's the code you need to add to your script.

if ($MyInvocation.MyCommand.CommandType -eq "ExternalScript")
{ $ScriptPath = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition }
else
{ $ScriptPath = Split-Path -Parent -Path ([Environment]::GetCommandLineArgs()[0]) }
