Confusing warning about a constant decimal field in C#

Question

I was experimenting with the const modifier while exploring a plethora of C# tutorials, and placed a bunch of const modifiers in a class like this

Answer 1

Int is a simple value type of a fixed size. Decimal is a bit more complicated due to scale. If you decompile your code, you'll find that it looks like this:

[DecimalConstant(0, 0, 0, 0, 1)]
private readonly static decimal somedecimal;

private const int someint = 2;

Where the decimal is not a constant, but has a DecimalConstant attribute courtesy of mscorlib.dll, where the true definition if decimal is:

public struct Decimal : IFormattable, IComparable, IConvertible,
IDeserializationCallback, IComparable<decimal>, IEquatable<decimal>
