"Where" clause doesn't work from C# when connecting to Exchange Online

I connect to Exchange Online via C# and can run a Get-Mailbox command without problem. But when I try
Get-Mailbox | Where LitigationHoldEnabled -eq $true
I get an error
The term 'where.exe' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
The command runs just fine in PowerShell.
What am I missing?
PSCredential credential = new PSCredential("xxxxx#yyyyyyyy.de", secpassword);
string connectionUri = "https://outlook.office365.com/powershell-liveid/";
Runspace runspace = System.Management.Automation.Runspaces.RunspaceFactory.CreateRunspace( );
PowerShell powershell = PowerShell.Create();
PSCommand command = new PSCommand();
command.AddCommand("New-PSSession");
command.AddParameter("ConnectionUri", new Uri(connectionUri));
command.AddParameter("ConfigurationName", "Microsoft.Exchange");
command.AddParameter("Credential", credential);
command.AddParameter("Authentication", "Basic");
command.AddParameter("AllowRedirection", true);
powershell.Commands = command;
runspace.Open();
powershell.Runspace = runspace;
Collection<System.Management.Automation.PSObject> result = powershell.Invoke();
if (powershell.Streams.Error.Count > 0 || result.Count != 1)
{
powershell.Dispose();
runspace.Dispose();
}
command = new PSCommand();
command.AddCommand("Invoke-Command");
command.AddParameter("ScriptBlock", System.Management.Automation.ScriptBlock.Create("Get-Mailbox | Where-Object LitigationHoldEnabled - eq $true"));
command.AddParameter("Session", result[0]);
powershell.Commands = command;
var Searches = powershell.Invoke();
....
powershell.Dispose();
runspace.Dispose();

quser (query user) no result in powershell c#

I've been searching the solution of this problem for weeks now and still blocked...
I need to use the program "quser" in powershell but in my C# program.
If I run "quser" just in the powershell console I have a result.
But when I execute a powershell script with "quser", it returns nothing... That's weird.
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
String script = "$re = '(\\S+)\\s+?(\\S*)\\s+?(\\d+)\\s+(\\S+)\\s+(\\S+)\\s+(\\d+\\/\\d+\\/\\d+\\s+\\d+:\\d+)'\n"
+ "query user /server:"+machine+" | Where-Object { $_ -match $re } | ForEach-Object {\n"
+ "New-Object -Type PSCustomObject -Property #{"
+ "'Username' = $matches[1]\n"
+ "'LogonTime' = $matches[6]\n"
+ "}\n"
+ "} | Select-Object Username, LogonTime | ForEach-Object { Write-Output (\"{0} is connected from {1}\" -f $_.Username, $_.LogonTime) }";
ps.AddScript(script);
Collection<PSObject> result = ps.Invoke();
ps.Dispose();
runspace.Close();
runspace.Dispose();
Console.WriteLine(result.Count);
The result of the ps.Invoke() is empty.
But when I run this code from a powershell console it works.
Also another weird thing, it works in remote powershell :
String script = "$re = '(\\S+)\\s+?(\\S*)\\s+?(\\d+)\\s+(\\S+)\\s+(\\S+)\\s+(\\d+\\/\\d+\\/\\d+\\s+\\d+:\\d+)'\n"
+ "query user | Where-Object { $_ -match $re } | ForEach-Object {\n"
+ "New-Object -Type PSCustomObject -Property #{"
+ "'Username' = $matches[1]\n"
+ "'LogonTime' = $matches[6]\n"
+ "}\n"
+ "} | Select-Object Username, LogonTime | ForEach-Object { Write-Output (\"{0} is connected from {1}\" -f $_.Username, $_.LogonTime) }";
string shellUri = "http://schemas.microsoft.com/powershell/Microsoft.PowerShell";
System.Security.SecureString sString = new System.Security.SecureString();
foreach (char passwordChar in password.ToCharArray())
{
sString.AppendChar(passwordChar);
}
PSCredential credential = new PSCredential(username, sString);
WSManConnectionInfo connectionInfo = new WSManConnectionInfo(false, machine, 5985, "/wsman", shellUri, credential);
List<String> scriptOutput = new List<String>();
using (Runspace runspace = RunspaceFactory.CreateRunspace(connectionInfo))
{
runspace.Open();
Pipeline pipe = runspace.CreatePipeline();
pipe.Commands.AddScript(script);
Collection<PSObject> result = pipe.Invoke();
foreach (PSObject line in result)
{
scriptOutput.Add(line.ToString());
}
pipe.Dispose();
runspace.Close();
}
foreach(String line in scriptOutput)
{
Console.WriteLine(line);
}
It returns the connected user.
The fact is that I don't want to logged into the machine in order to see the conncted users. (because it works in the powershell console)
If someone could help me please.
Thanks.

running powershell with parameters in c# and writting those parameters in Text File

I am trying to run a powershell script in c#
here is the first test script
param(
[string] $computer,
[string] $password
)
out-file -filepath C:\File\parameter.txt -inputobject $computer -encoding ASCII -width 50 -Append
out-file -filepath C:\File\params.txt -inputobject $password -encoding ASCII -width 50 -Append
out-file -filepath C:\File\Sys32.txt -inputobject $password -encoding ASCII -width 50 -Append
and here is my C# supposed to run the powershellscript
private void testRunningPowershell()
{
string mypass = gettingPass();
using (Runspace runspace = RunspaceFactory.CreateRunspace())
{
runspace.Open();
runspace.SessionStateProxy.Path.SetLocation("C:\\Users\\robert\\Desktop\\Titanium\\");
RunspaceInvoke runSpaceInvoker = new RunspaceInvoke(runspace);
//runSpaceInvoker.Invoke("Set-ExecutionPolicy Unrestricted");
// create a pipeline and feed it the script text (AddScript method) or use the filePath (Add method)
using (Pipeline pipeline = runspace.CreatePipeline())
{
Command command = new Command(#"C:\Users\robert\Desktop\Titanium\Titanium2.ps1");
dictionaryParams.Remove("FriendlyName");
foreach (var item in dictionaryParams)
{
if (item.Key == (string)comboBoxScreen.SelectedItem)
{
CommandParameter testParam = new CommandParameter(null, item.Value);
CommandParameter testParam2 = new CommandParameter(null, mypass);
command.Parameters.Add(null, testParam);
command.Parameters.Add(null, testParam2);
}
}
pipeline.Commands.Add(command);
var results = pipeline.Invoke();
ReturnInfo ri = new ReturnInfo();
foreach (PSObject p in results)
{
Hashtable ht = p.ImmediateBaseObject as Hashtable;
ri.ReturnText = (string)ht["ComputerName"];
ri.ReturnText = (string)ht["password"];
}
runspace.Close();
}
}
}
my purpose is to test if the cmdlet is run with the right parameters
I've got a windows form app that allow the user to choose the parameter
I would like to get my parameter value written in Text File (.txt)
instead I am getting this
System.Management.Automation.Runspaces.CommandParameter
instead of the parameter's value choosen

Error message when running a c# powershell code

When I run the code below I get the following error at Response.Write( result.Properties["name"].Value);. "use the 'new' keyword to create and object instance."
I can't figure out how to fix this problem.
String sEmailAddress;
String sPassword;
sEmailAddress = Request.QueryString["value1"];
sPassword = Request.QueryString["value2"];
lbl1.Text = sEmailAddress + " " + sPassword;
SecureString sSecurePW = new SecureString();
foreach (char c in sPassword.ToCharArray())
sSecurePW.AppendChar(c);
PSCredential Credential = new PSCredential(sEmailAddress, sSecurePW);
PowerShell powershell = PowerShell.Create();
powershell.Runspace.SessionStateProxy.SetVariable("cred", Credential);
powershell.AddScript("$s = New-PSSession -ComputerName ExchDC01 -Credential $cred -Authentication Kerberos");
powershell.AddScript("invoke-command -session $s -scriptblock {Get-ADOrganizationalUnit -LDAPFilter '(name=*)' -SearchBase 'OU=TENANTS,DC=lab,DC=local' -SearchScope OneLevel | ft Name}");
// Collection<PSObject> results = powershell.Invoke();
foreach (PSObject result in powershell.Invoke())
{
Response.Write(result.Properties["name"].Value); //<-- Error:use the 'new' keyword to create and object instance.
}
}
Thanks in advance

Error while running AD commandlets in powershell from C#

I have tried executing AD commandlets in powershell using C# from the same machine. This works fine.
static void Main(string[] args)
{
InitialSessionState iss = InitialSessionState.CreateDefault();
iss.ImportPSModule(new string[] { "activedirectory" });
Runspace myRunSpace = RunspaceFactory.CreateRunspace(iss);
myRunSpace.Open();
Pipeline pipeLine = myRunSpace.CreatePipeline();
Command myCommand = new Command("Get-ADUser");
myCommand.Parameters.Add("Filter", "sAMAccountName -eq 'user1'");
//myCommand.Parameters.Add("IncludeDeletedObjects");
pipeLine.Commands.Add(myCommand);
//Command restoreCommand = new Command("Restore-ADObject");
//pipeLine.Commands.Add(restoreCommand);
Console.WriteLine("Before Invoke");
Collection<PSObject> commandResults = pipeLine.Invoke();
Console.WriteLine("After Invoke");
foreach (PSObject cmdlet in commandResults)
{
//Console.WriteLine("Inside foreach");
string cmdletName = cmdlet.BaseObject.ToString();
System.Diagnostics.Debug.Print(cmdletName);
Console.WriteLine(cmdletName);
}
Console.ReadLine();
}
But while trying to run the same command remotely using the invoke command it gives the error The term 'Get-ADUser' is not recognized as the name of a cmdlet, function, script file, or operable program.
The following is my program :
static void Main(string[] args)
{
string shellUri = "http://schemas.microsoft.com/powershell/Microsoft.PowerShell";
string userName = "Domain\\Administrator";
string password = "Password";
SecureString securePassword = new SecureString();
foreach (char c in password)
{
securePassword.AppendChar(c);
}
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();
new1.AddCommand("Get-ADUser");
new1.AddParameter("identity", "CN=user1,DC=example,DC=com");
powershell.Commands = new1;
Collection<PSObject> results = powershell.Invoke();
foreach (PSObject obj in results)
{
PSMemberInfoCollection<PSPropertyInfo> propInfos = obj.Properties;
Console.WriteLine("********************");
foreach (PSPropertyInfo propInfo in propInfos)
{
string propInfoValue = (propInfo.Value == null) ? "" : propInfo.Value.ToString();
Console.WriteLine("{0} --> {1}", propInfo.Name, propInfoValue);
}
}
}
}
}
How can I achieve calling AD commandlets remotely?
Is there a way to invoke commands remotely using InitialSessionState rather than WSManConnectionInfo .
If I use invoke-command -computername $DC -ScriptBlock {Remove-ADUser -identity "user1"} -credential $cred - i get the error The term 'Remove-ADUser' is not recognized as the name of a cmdlet, function, script file, or operable program.
But it is possible to use command Remove-ADUser -identity "user1" -server $DC -credential $cred .How to directly execute the AD command in powershell from C# client?

You need to import the ActiveDirectory module in the remote runspace before executing the AD command e.g.:
powershell.Commands.AddCommand("Import-Module").AddArgument("ActiveDirectory");
powershell.Invoke();
powershell.Commands.Clear();
