c# - Should an Enum start with a 0 or a 1?

Question

Imagine I have defined the following Enum:

public enum Status : byte
{
    Inactive = 1,
    Active = 2,
}

What's the best practice to use enum? Should it start with 1 like the above example or start with 0 (without the explicit values) like this:

public enum Status : byte
{
    Inactive,
    Active
}

Framework Design Guidelines:

?? DO provide a value of zero on simple enums.

Consider calling the value something like "None." If such a value is not appropriate for this particular enum, the most common default value for the enum should be assigned the underlying value of zero.

Framework Design Guidelines / Designing Flag Enums:

? AVOID using flag enum values of zero unless the value represents "all flags are cleared" and is named appropriately, as prescribed by the next guideline.

?? DO name the zero value of flag enums None. For a flag enum, the value must always mean "all flags are cleared."
