It seems to be as easy as:
[DllImport("YourDllName.dll")]
public static extern int GetObjects(ref string data, int length);
// To call it...
string theData = string.Empty;
// Pad the string just in case
theData = theData.PadLeft(101,' ');
GetObjects(ref theData, 100);
I haven't fully tested it yet, but that seems to work.
