powershell return each drive empty space of machine in c#

Question

I want to get empty space of every drive of server with powershell using C#

this is the powershell script which works fine

Get-PSDrive |Format-Table

what I want is to take output of this script and show it on UI

What I tried till now.

      string scriptToCheckDBServerMemorySpace = "Get-PSDrive |Format-Table";
      using (PowerShell PowerShellInstance = PowerShell.Create())
      {
                    PowerShellInstance.AddScript(scriptToCheckDBServerMemorySpace);

                    Collection<PSObject> PSObject = PowerShellInstance.Invoke();

                    foreach (PSObject PSOutputItem in PSObject)
                    {
                        if (PSOutputItem != null)
                        {

                            //TxtFirstStepResult.Text = PSOutputItem.BaseObject.ToString() + "\n";
                        }
                    }
                    if (PowerShellInstance.Streams.Error.Count > 0)
                    {
                        TxtFirstStepResult.Text = PowerShellInstance.Streams.Error.ToString() + "\n";
                    }
                    Console.ReadKey();
       }

the question is how to get output of this powershell script and show it on windows form application. I am not able to figure out how to convert this PS object and convert it to readable format.

please redirect me to the right direction.

The problem you have is that you are getting back formatted data from your script:

"Get-PSDrive |Format-Table"

The data isn't in a nice table as you'd see in the console - you will need to extract it and display it yourself. A better option is to get the 'raw' objects and format these directly. For example, here's some basic console formatting:

string scriptToCheckDBServerMemorySpace = "Get-PSDrive";
            using (PowerShell PowerShellInstance = PowerShell.Create())
            {
                PowerShellInstance.AddScript(scriptToCheckDBServerMemorySpace);

                Collection<PSObject> PSObject = PowerShellInstance.Invoke();

                foreach (PSObject PSOutputItem in PSObject)
                {
                    if (PSOutputItem != null)
                    {

                        Console.WriteLine($"Drive: {PSOutputItem.Members["Name"].Value}, Provider: {PSOutputItem.Members["Provider"].Value}");
                    }
                }
                if (PowerShellInstance.Streams.Error.Count > 0)
                {
                    //TxtFirstStepResult.Text = PowerShellInstance.Streams.Error.ToString() + "\n";
                }

                Console.ReadKey();
            }

I want to show memory space. how to show it. it is only showing provide name — Ameya Deshpande, Oct 10 '18 at 10:51
@AmeyaDeshpande, you can use the same technique my example uses to access/display any of the properties of the drive. For example: `PSOutputItem.Members["Free"].Value`, `PSOutputItem.Members["Used"].Value`, etc. Use `Get-PSDrive | Get-Member` to see what is available. — boxdog, Oct 10 '18 at 10:54
Looks like 'Free' and 'Used' are script properties, so are only evaluated at access time, which is after you've left your session. An option that springs to mind (but I don't have time to test), is to use `Add-Member` in your original script to add a couple of corresponding `NoteProperty` members to the objects when they are originally created. — boxdog, Oct 10 '18 at 11:10
I am new to powershell and frankly I don't have any idea what you are talking about :| — Ameya Deshpande, Oct 11 '18 at 09:45
