First, You need to add a reference to System.Management.Automation
in your C# project.
How to run powershell in C#?
You can create an instance of the PowerShell
class and run commands.
For example:
using System; using System.Management.Automation; // powershell c# command class Program { // run powershell in c# static void Main(string[] args) { // Create an instance of PowerShell using (PowerShell PowerShellInstance = PowerShell.Create()) { // Add the script/command you want to run PowerShellInstance.AddScript("Get-Process"); // Invoke the command asynchronously. var asyncResult = PowerShellInstance.BeginInvoke(); // Wait for the command to complete while (!asyncResult.IsCompleted) { Console.WriteLine("Waiting for PowerShell to finish..."); System.Threading.Thread.Sleep(1000); } Console.WriteLine("Command completed."); // Get the results of the command foreach (PSObject result in PowerShellInstance.EndInvoke(asyncResult)) { Console.WriteLine(result.ToString()); } } Console.ReadLine(); } }
We create an instance of PowerShell
, then we add the PowerShell command or script using the AddScript
method.
If you want to invoke a PowerShell cmdlet, you can use AddCommand
in place of AddScript
.
// Add the Get-Process cmdlet, powershell c# cmdlet run powershell.AddCommand("Get-Process"); // Execute the command and capture the output var results = powershell.Invoke();
Next, We invoke the command asynchronously using BeginInvoke
, then we wait for the command to complete by checking the IsCompleted
property.
Once the command is completed, we retrieve the results using EndInvoke
, we will display the result in our console.
You can replace "Get-Process"
with any PowerShell command or script you want to execute. Make sure to handle errors and exceptions appropriately in your production code.
You can also run more complex PowerShell scripts or commands that require parameters.
For example:
// Add a script with parameters powershell.AddScript("$param1 = 'Hello'; $param2 = 'World'; Write-Output $param1 $param2"); // Execute the script var results = powershell.Invoke();
In this case, the script defines two variables ($param1
and $param2
), and outputs them together.
