Invoke SharePoint 2010 PowerShell cmdlets from VS 2010

Posted by TK on 3/17/2010 8:33 PM | Comments (1)

Here is the code snippet that would invoke SharePoint 2010 Powershell cmdlets from VS 2010

private void invokeSPCmdlet()

        {

            // create runspace configuration

            RunspaceConfiguration config = RunspaceConfiguration.Create();

  

            // PSSnapIn exception object

            PSSnapInException Ex = null;

  

            try

            {

                //add Microsoft SharePoint PowerShell SnapIn

                PSSnapInInfo pssnap = config.AddPSSnapIn("Microsoft.SharePoint.PowerShell", out Ex);

  

                //create powershell runspace

                Runspace cmdlet = RunspaceFactory.CreateRunspace(config);

  

                cmdlet.Open();

  

                RunspaceInvoke scriptInvoker = new RunspaceInvoke(cmdlet);

  

                // set powershell execution policy to unrestricted

                scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted");

  

                // create a pipeline and load it with command object

                Pipeline pipeline = cmdlet.CreatePipeline();

  

                Command cmd = new Command("Get-SPSite"); // Using Get-SPFarm powershell command

                pipeline.Commands.Add(cmd);

  

  

                pipeline.Commands.Add("Out-String"); // this will format the output

                IEnumerable<PSObject> output = pipeline.Invoke();

  

                pipeline.Stop();

                cmdlet.Close();

  

                // process each object in the output and append to stringbuilder

                StringBuilder results = new StringBuilder();

                foreach (PSObject obj in output)

                {

                    results.AppendLine(obj.ToString());

                }

                //set the output to a multi-line text box

                textBox1.Text = results.ToString();

            }

            catch (Exception exError)

            {

                MessageBox.Show(exError.Message.ToString());

            }

        }



You have to reference System.Management.Automation and include the following statements

using System.Management.Automation;
using System.Management.Automation.Runspaces;

There are various ways to invoke SP 2010 cmdlets, but the code snippet shows using RunspaceConfiguration to achieve this. On pasting the method into a standard windows form with a command button and text box, this is what the output would look like
