How to add C# code in PowerShell script for adding a SharePoint list item

In this article we will be creating C# code to add an item in the SharePoint list. Then we will make the C# code as a powershell script.

C# Code:
 using System;
 using Microsoft.SharePoint;
 

namespace Vijai.Script
 {
  public static class AddanItem
     {
  public static void Add()
         {
  using (SPSite site = new SPSite("http://ServerName:12345/"))
             {
  using (SPWeb web = site.OpenWeb())
                 {
                     web.AllowUnsafeUpdates = true;
  SPList list=web.Lists["CustomList"];
  SPListItem item = list.Items.Add();
                     item["Title"] = "Test";
                     item.Update();
                 }
             }
         }
     }
 }
 

Adding C# code in PowerShell script:
 

CSharpScript.ps1
 $assembly = ("Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c")
 $code = @"
 using System;
 using Microsoft.SharePoint;
 namespace Vijai.Script
 {
     public static class AddanItem
     {
         public static void Add()
         {
             using (SPSite site = new SPSite("http://ServerName:12345/"))
             {
                 using (SPWeb web = site.OpenWeb())
                 {
                     web.AllowUnsafeUpdates = true;
                     SPList list=web.Lists["CustomList"];
                     SPListItem item = list.Items.Add();
                     item["Title"] = "Test";
                     item.Update();
                 }
             }
         }
     }
 }
