Question

i need to implement some kind of bit to status mapping and i don’t know how to implement this thing – maybe i have a blockhead 😉

Okay so i have a status-code which can be max. 32 bit long for example 1001 0011
Each bit belongs to a special status code – string.

For example:

Bit 1: String Cancel
Bit 2: String Okay
Bit 3: String Save
....
Bit 32: String Next

Now i have to determine which bits are set and return all status code – strings which are set int the 32 bit long status.

I like to prefer some kind of dictionary or sumthin like that where i can store for each bit the corresponding status code.

Then i like to loop thru the 32 bit long status code and get the corresponding status code string out of the dictionary – store it in a string and return it after the 32 bit long status code has been looped through.

Somebody has an idea for that?

Answer 1

you can use enums with flags attribute. Enum can be cast from and to int.
Each enum value can be set so your status can look like this

[Flags]
enum Status { None = 0 , Cancel = 1 , Ok = 2 , Save = 4 ... } 

Flags attribute

Indicates that an enumeration can be treated as a bit field; that is,
a set of flags.

you can test with

 if ((status & Status.Ok) == Status.Ok)
 {
 // Do something
 }
