A better way to write null reference with return value in c#

Question

Is there a better way to write this null check? I'm checking a table from a DataSet for nulls.

if (dataSet == null || dataSet.Tables == null || dataSet.Tables[0].Rows == null)
{
    Console.WriteLine($"Error at {nameof(dataSet)}");
    return vatPeriodList;
}

I'm working in ADO.NET.

Try

if(dataSet?.Tables?.FirstOrDefault()?.Rows == null) {}

FirstOrDefault() returns the first entry or null if there is none.
