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

Updated: Mar 29, 2019

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();                 }             }         }     } } "@


Add-Type -ReferencedAssemblies $assembly -TypeDefinition $code -Language CSharp


[Vijai.Script.AddanItem]::Add()


write-host -foreground "green" "An item added successfully to the SharePoint List"
