it's already running?

If you mean command line arguments, you can call GetCommandLine().

I tried importing GetCommandLine() like this:
[DllImport("Coredll.lib", CharSet=CharSet.Auto, SetLastError=true)]
static extern string GetCommandLine();

This returns void, even if there is an argument passed to the main function
in .Net.
Do I have to marshal the return value somehow?

I've changed the import to coredll.dll now.
[DllImport("coredll.dll", CharSet=CharSet.Auto, SetLastError=true)]

While calling the function I get a System.NotSupportedException.

The Marshaler doesn't support returning strings from the P/Invoke. Try to use
IntPtr instead and then use Marshal.PtrToStringUni to get the string.

Hi,

does anybody have some advice in this regard?
Maybe the function has to be imported in a different way?

Alex already gave you the right answer:

[DllImport("coredll.dll", CharSet=CharSet.Auto, SetLastError=true)]
static extern IntPtr GetCommandLine();

//sample call
{
string args = Marshal.PtrToStringUni(GetCommandLine())
}

my return is args[] + " //i". Dont know if it will happen on your app too
since my ROM is a test buildso the extra " //i" might be a bug. Just ignore
it if you see the bastard.
