Try load module in this way:

PowerShell powershell = PowerShell.Create();
powerShell.Commands.AddCommand("Import-Module").AddParameter("Name", "c:\vm\vm.psd1'");

or

PowerShell powershell = PowerShell.Create();
powershell.Commands.AddCommand("Add-PsSnapIn").AddParameter("Name", "virtualmachinemanager");

With a pipeline try create an InitialSessionState

InitialSessionState iss = InitialSessionState.CreateDefault();
           iss.ImportPSModule(new string[] { @"C:\vm\vm.psd1"});
           Runspace runSpace = RunspaceFactory.CreateRunspace(iss);
           runSpace.Open();

then use your code with pipeline to run cmdlet from module loaded

pipeline.Commands.Add return void. i use such as

Command cmd = new Command("Import-Module");             cmd.Parameters.Add(new CommandParameter("Name", @"C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin\psModules\virtualmachinemanager\virtualmachinemanager.psd1"));             pipeline.Commands.Add(cmd);

but it doesn't work too.

@Baris I'm sorry, it works on Powershell Class.. not in a pipeline object. Add other solution.

thanks for answer but how do i use PowerShell class? i use only pipeline for execute commands. i try use PowerShell class such as before run script:

PowerShell ps = PowerShell.Create();             ps.Commands.AddCommand("Import-Module")               .AddParameter("Name",                             @"C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin\psModules\virtualmachinemanager\virtualmachinemanager.psd1");             ps.Invoke();

but it doesn't work. how do i use it?

@Baris have you tried with InitialSessionState and pipeline as in my last example in answer? Should works!

Try something like this for loading the snapin and executing your commands:

using System.Management.Automation.Runspaces;

//...

var rsConfig = RunspaceConfiguration.Create();
using (var myRunSpace = RunspaceFactory.CreateRunspace(rsConfig))
{
    PSSnapInException snapInException = null;
    var info = rsConfig.AddPSSnapIn("FULL.SNAPIN.NAME.HERE", out snapInException);

    myRunSpace.Open();
    using (var pipeLine = myRunSpace.CreatePipeline())
    {
        Command cmd = new Command("YOURCOMMAND");
        cmd.Parameters.Add("PARAM1", param1);
        cmd.Parameters.Add("PARAM2", param2);
        cmd.Parameters.Add("PARAM3", param3);

        pipeLine.Commands.Add(cmd);
        pipeLine.Invoke();
        if (pipeLine.Error != null && pipeLine.Error.Count > 0)
        {
            //check error
        }
    }
}
