Execute C# code using Powershell [duplicate]

Question

Can I write a C# script code and execute it using PowerShell?

Instead of running C# using command line tools provided by Visual Studio, I want to write C# script using Notepad++ and execute the code using PowerShell.

Answer 1

Using C# Code in PowerShell

"Customer like scripting languages as it allows them to write custom code without a need to run a compiler or to copy new executables to their production machines which usually requires a more complex approval process than deploying a script file or even to execute the commands within a command shell.

So it would be great if the existing C# code could be reused inside PowerShell without a need to implement it as Cmdlet."

$Assem = (
...add referenced assemblies here...
    )

$Source = @"
...add C# source code here...
"@

Add-Type -ReferencedAssemblies $Assem -TypeDefinition $Source -Language CSharp
