C# PowerShell create blank text file on desktop

Question

I'm trying to use PowerShell from C# to create a new file on desktop. In the terminal you would do:

cd desktop
$null >> newfile.txt

So I'm trying to do this in C# to mimic the previous statements:

using (PowerShell PowerShellInstance = PowerShell.Create())
{
  PowerShellInstance.AddScript("cd desktop; $null >> newfile.txt");

  PowerShellInstance.Invoke();
}

This runs without any exceptions but the file isn't created on the desktop. Can anyone point out what I'm doing wrong with the AddScript?

EDIT

It looks like the problem comes from using cd and then the create in sequence.

I was able to get it working by doing

PowerShellInstance.AddScript("$null >> C:\\users\\me\\Desktop\\newfile.txt");

If anyone knows how to do a cd command followed by another please let me know.

To me it looks like the command cd desktop itself is not working. If you open a powershell console then he default path it opens up in is C:\Users\user_name\ and most probably from c# it's not opening with that path rather instead is opening with the working directory being the debug folder of your current project; [as commented by @Nived]

There is no issue with your current code. Just change the script statement to below and it should work fine

cd C:\Users\user_name\desktop; $null >> newfile.txt

With that your C# code should be something like

using (PowerShell PowerShellInstance = PowerShell.Create())
 {
  PowerShellInstance.AddScript(@"cd C:\Users\user_name\desktop; $null >> newfile.txt");

 PowerShellInstance.Invoke();
}
