Initialization of C # Enumeration

1. The question

Code #01

class Tester
{
　static void Main()
　{
　　　　Alignment a = new Alignment();
　　　　Console.WriteLine(a.ToString("D"));
　　　　Alignment b = Alignment.Left;
　　　　Console.WriteLine(b.ToString("D"));
　　}
}

Assuming left is the first member of the alignment enumeration, do you think the two initialization enumeration variables are equivalent? If not, what is the difference between them?

2. Comparison of two kinds of initialization methods

2.1 The value of the first enumeration member is 0

If we do not specify the value of the first member for alignment:

//Code #02
enum Alignment
{
　　Left,
　　Center,
　　Right
}

Code #01的输出结果将是:

0

0
