C# compiler complains about misusing local variable before when there are none

Am I blind? Where is the local variable?

1>d:\path\Start.cs(99,11,99,20): error CS0844: Cannot use local variable '_mainAssy' before it is declared. The declaration of the local variable hides the field

Also same error lines 100, 102, 105.

private AssyFile _mainAssy = null;
private AssyFile MainAssy()
{
  if (_mainAssy != null) // this is line 99.
     return _mainAssy;
  try
  {
    _mainAssy = new AssyFile(Application.ActiveDocument as AssemblyDocument);
  }
  catch
  {
    _mainAssy = documents.CreateAssy(); 
  }

  returrn _mainAssy;
}

EDIT: added missing try and catch statements. (Before removed to try to resolve bug. Current question is: Why does mispelling 'return' cause this compiler message?

The problem is here:

returrn _mainAssy;

Because you misspelled return, the compiler doesn't recognize the keyword. So it thinks returrn is a type, and returrn _mainAssy is the declaration for a variable _mainAssy of type returrn...
