Powershell & C# to check if host available

Question

Hi All,
I have a c# code segment which process a power-shell script. The following is the code segment.
Runspace objRunspace = null;
objRunspace = RunspaceFactory.CreateRunspace();
objRunspace.Open();
PowerShell powershell = PowerShell.Create();
powershell.Runspace = objRunspace;
powershell.AddScript("my powershell script");
Collection<PSObject> objPS1 = powershell.Invoke();
if (objPS1.Count == 0)
//I Assumes that the PC is down
In this case, If the login credentials are wrong or if that particular PC is not available; the ObjPS1.count will be zero. If that count is Zero, I assumes that the host is unavailable. But in accuracy point of view, I want to identify both these (wrong
credentials / host unavailable) situations separate. Is there a better way or different approach to achieve the same.
Thanks in advance
Sebastian

Hi Sebastian,
In addition, these examples may be helpful for you to handle the error when call powershell script in C#:
// invoke execution on the pipeline (collecting output)
Collection<PSObject> PSOutput = PowerShellInstance.Invoke();
// check the other output streams (for example, the error stream)
if (PowerShellInstance.Streams.Error.Count > 0)
// error records were written to the error stream.
// do something with the items found.
