I have a dll generated from a C# code. Need help in writing function that calls event handler from dll.

I'm created an object called pulsar and trying to call the 'sendcommand' using the below that doesn't work

pulsar.Client.SendCommand("my command", ?? )

Below is the C# code:

public partial class Form : System.Windows.Forms.Form
{         private void enableSignGenButton_Click(object sender, EventArgs e)
    {
    string command = string.Format(PulsarCommands.GlobalEnableSignalGenerator, SelectedSystem, true);
    pulsar.Client.SendCommand<string>(command, SigGenEnabledStatus);
    }
    private void SigGenEnabledStatus(object? sender, string e)  { }
    }
public class Client
{
    public async Task SendCommand<T>(string command, EventHandler<T> eventHandler, string parameter = "")
    {
    Progress<T> progress = new Progress<T>();
    progress.ProgressChanged += eventHandler;
    Task t = GetAsync<T>(command, progress, parameter);
    await t;
    return;
}
}

Is there a Matlab component to this?

dllPath = fullfile('C:\Matlab_Projects\Analysis\Simulink\PlatformSim\dll','PulsarWebClientLibrary.dll');
pkg = NET.addAssembly(dllPath);
pulsar = PulsarWebClientLibrary.Pulsar("http://lptp_kiruthika/api/");
Version = pulsar.Client.Version;
obj = pulsar.Client.CheckVersion(Version);
if pulsar.Client.Connected == 1
    fprintf('Pulsar is Connected\n')
else
    fprintf('Pulsar is not Connected\n')
    
end
%%  Calling method that has input arguments
command = "pulsar/GlobalEnableSignalGenerator?SystemName=FLA&enable=True";
object = pulsar.Client.SendCommand1(command,SigGenEnabledStatus);
function SigGenEnabledStatus()
end
