how to declare a const byte[]

[Romain TAILLANDIER]

hi group !

How can i declare a const byte[] in C# ?

const byte[] ByteArray = new byte[] { 69, 110, 99}; // Error : the
expression must be constante
const byte[] ByteArray = { 69, 110, 99}; // Error , the table initialisators
can be used only to initialize variables, try the operator new


i try a few others, but i allreadey have erro like those.
so solve the probleme by using a read only property.
but how could i declare a const byte array ?

thanks
ROM

You can't - consts are for compile-time constant values. An array is a
reference type, and the value itself therefore can't be a constant,
even though the contents are.

You can make the variable readonly, although that won't stop anyone
from changing the contents of the byte array.

Constants are value types, so you cannot do this directly. There are ways to
repeat similar funcationality, however, without making constants. Without
understanding what, and more important why, you are doing something, I cannot
give you a great solution here.

Not necessarily. You can declare constants of reference types too,
although the values are restricted to string literals and null.

Use " static readonly byte[] ByteArray = { 69, 110, 99 }; " instead, I hope it will help
