To call a powershell script file (example.ps1) from C#
I tried running a script localwindows.ps1 from C# using the following Code :
PSCredential credential = new PSCredential(userName, securePassword);
WSManConnectionInfo connectionInfo = new WSManConnectionInfo(false, "machineName", 5985, "/wsman", shellUri, credential);
using (Runspace runspace = RunspaceFactory.CreateRunspace(connectionInfo))
{
runspace.Open();
String file = "C:localwindows.ps1";
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(file);
pipeline.Commands.Add("Out-String");
Collection<PSObject> results = pipeline.Invoke();
}
But getting exception :'The term 'C:localwindows.ps1' is not recognized as the name of a cmdlet, function, script file, or operable program.
So I tried the following :
PSCredential credential = new PSCredential(userName, securePassword);
WSManConnectionInfo connectionInfo = new WSManConnectionInfo(false, "machineName", 5985, "/wsman", shellUri, credential);
using (Runspace runspace = RunspaceFactory.CreateRunspace(connectionInfo))
{
runspace.Open();
using (PowerShell powershell = PowerShell.Create())
{
powershell.Runspace = runspace;
PSCommand new1 = new PSCommand();
String machinename = "machinename";
String file = "C:localwindows.ps1";
new1.AddCommand("Invoke-Command");
new1.AddParameter("computername", machinename);
new1.AddParameter("filepath", file);
powershell.Commands = new1;
Console.WriteLine(powershell.Commands.ToString());
Collection<PSObject> results = powershell.Invoke();
}
I am getting the error : "Cannot find path 'C:localwindows.ps1' because it does not exist."
But using command 'Invoke-Command -ComputerName "machineName" -filepath C:localwindows.ps1' ,from powershell in local machine created a new account in the remote machine.
How to call the script localwindows.ps1 from C#? How to execute the command 'Invoke-Command -ComputerName "machineName" -filepath C:localwindows.ps1' through C#?
The script localwindows.ps1 is
$comp = [adsi]“WinNT://machinename,computer”
$user = $comp.Create(“User”, "account3")
$user.SetPassword(“change,password.10")
$user.SetInfo()
Actually your invocation style should work. But in both of your examples, the script c:localwindows.ps1 must reside on the local computer. In the Invoke-Command case, it will be copied from the local computer to the remote computer.
If, in the Invoke-Command case, the script already exists on the remote computer and you don't need to copy it over, remove the FilePath parameter and add this:
new1.AddParameter("Scriptblock", ScriptBlock.Create(file));
I've got an article that describes an easy way to run Powershell through WinRM from .NET at http://getthinktank.com/2015/06/22/naos-winrm-windows-remote-management-through-net/.
The code is in a single file if you want to just copy it and it's also a NuGet package that includes the reference to System.Management.Automation.
It auto manages trusted hosts, can run script blocks, and also send files (which isn't really supported but I created a work around). The returns are always the raw objects from Powershell.
// this is the entrypoint to interact with the system (interfaced for testing).
var machineManager = new MachineManager(
"10.0.0.1",
"Administrator",
MachineManager.ConvertStringToSecureString("xxx"),
true);
// for your specific issue I think this would be easier
var results = machineManager.RunScript(
File.ReadAllText("C:LocalWindows.ps1"));
// will perform a user initiated reboot.
machineManager.Reboot();
// can run random script blocks WITH parameters.
var fileObjects = machineManager.RunScript(
"{ param($path) ls $path }",
new[] { @"C:PathToList" });
// can transfer files to the remote server (over WinRM's protocol!).
var localFilePath = @"D:TempBigFileLocal.nupkg";
var fileBytes = File.ReadAllBytes(localFilePath);
var remoteFilePath = @"D:TempBigFileRemote.nupkg";
machineManager.SendFile(remoteFilePath, fileBytes);
Please mark as answer if this helps. I've been using this for a while with my automated deployments. Please leave comments if you find issues.
