Question

Hi all I’d like to copy a file to a computer and remote into said machine
and run a single command then gather the output file of that command. I’ve
been tasked to use Powershell to copy and remote into the machines.
I use this page to help start me out:
http://www.codeproject.com/Articles/18229/How-to-run-PowerShell-scripts-from-C
The program I’m using is .net 4 and has to stay that way. I first installed the windows sdk 3.5 then when the code didnt work I installed sdk 4.0 but I still get
the same error in my answer string: “Mixed mode assembly is built against version ‘v2.0.50727’ of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.\r\n”
Thanks for the help

Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open();
// create a pipeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript("Import-Module BitsTransfer" + Environment.NewLine + "Start-BitsTransfer -Source " + filename + " -Destination \\\\" + host + "\\" + uploadtodir + "\\"+Environment.NewLine);
// add an extra command to transform the script output objects into nicely formatted strings
// remove this line to get the actual objects that the script returns. For example, the script
// "Get-Process" returns a collection of System.Diagnostics.Process instances.

pipeline.Commands.Add("Out-String");
// execute the script

Collection<PSObject> results = new Collection<PSObject>();
try
{
   results = pipeline.Invoke();
}

catch (Exception ex)
{
   results.Add(new PSObject((object)ex.Message));
}

// close the runspace
runspace.Close();
// convert the script result into a single string

StringBuilder stringBuilder = new StringBuilder();

foreach (PSObject obj in results)
{
    stringBuilder.AppendLine(obj.ToString());
}

string answer= stringBuilder.ToString();

In the App.config file of the project you need to add this:

<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0"/>
  </startup>
</configuration>

If you don’t have an App.config file just create one.
Hope this helps you.
