C# dll in powershell

I want to do something to C # code executed from a script powershell. The question arose as to add a third-party library in the project?I am doing so

$path = @("C:\Users\name\Desktop\ch\packages\System.Data.SQLite.1.0.97.0")
$cSharp = @"my C# code"@
Add-Type -TypeDefinition $cSharp -ReferencedAssemblies $path

But when i start having problems running the script error:

This assembly name or codebase invalid. (Exception from HRESULT: 0x80131047).

I want to add the concrete version of the library System.Data.SQLite.dll
