System.Console.WriteLine(np.array(new string[,]{
  { null, null }, { null, null }
}))

throws

Error: System.Exception: Unable to determine array type. Could not find any non-null entries. Please specify dtype
at NumpyDotNet.np.FindFirstNonNullValue(Array ssrc)
at NumpyDotNet.np.asanyarray(Object a, dtype dtype, NPY_ORDER order)
at NumpyDotNet.np.FromAny(Object src, dtype descr, Int32 minDepth, Int32 maxDepth, NPYARRAYFLAGS flags, Object context)
at NumpyDotNet.np.CheckFromAny(Object src, dtype descr, Int32 minDepth, Int32 maxDepth, NPYARRAYFLAGS requires, Object context)
at NumpyDotNet.np.array(Object src, dtype dtype, Boolean copy, NPY_ORDER order, Boolean subok, Int32 ndmin)

However, specifying dtype does not change this fact. The same exception is still thrown.

System.Console.WriteLine(np.array(new string[,]{
  { null, null }, { null, null }
}, np.Strings))
