Embedding C# code

In this recipe, we will embed and execute C# code in our PowerShell script.

How to do it...

Let's explore how to embed C# code in PowerShell.

1. Open PowerShell ISE. Go to Start | Accessories | Windows PowerShell | Windows PowerShell ISE.

2. Add the following script and run it:

   #define code
   #note this can also come from a file
   
   $code = @"
   using System;
   public class HelloWorld
   {
      public static string SayHello(string name)
      {
         return (String.Format("Hello there {0}", name));
      }
      public string GetLuckyNumber(string name)
      {
         Random random = new Random();
         int randomNumber = random.Next(0, 100);
         string message = String.Format("{0}, your lucky" +
                          " number for today is {1}", 
                          name, randomNumber);
         return message;
      }
   }
   "@
   
   #add this code to current session
   Add-Type -TypeDefinition $code
   #call static method
   [HelloWorld]::SayHello("belle")
   
   #create instance
   $instance = New-Object HelloWorld
   
   #call instance...
