In C# how do you accomplish the same thing as a #define

Question

Coming from a C background I'm used to defining the size of the buffer in the following way:

#define BUFFER_SIZE 1024

uint8_t buffer[BUFFER_SIZE];

How would you do the accomplish the same thing in C#?

Also does the all-caps K&R style fit in with normal C# Pascal/Camel case?

Answer 1

public static readonly int BUFFER_SIZE = 1024;

I prefer this over a const due to the compiler shenanigans that can happen with a const value (const is just used for replacement, so changing the value will not change it in any assembly compiled against the original).

Answer 2

Don't use #define.

Define a constante: private const int BUFFER_SIZE or readonly variable: private readonly int BUFFER_SIZE

Answer 3

const int BUFFER_SIZE = 1024;

Do not use "static readonly" because it creates a variable. "const" are replaced at build time and do not create variables.

Answer 4

Personally, I prefer constants:

private const int BUFFER_SIZE = 1024;

Though, if it's public and you're a framework, you may want it to be a readonly to avoid client recompiles.
