C # Find variable by value
I am making an "error code to String" converter that will display the name of the error code from its value, for example it 0x000000c3
will give "Class not found"
, but using MY OWN error codes!
This is what it actually looks like:
#region errcodes
public int NORMAL_STOP = 0x00000000;
public int LIB_BROKEN = 0x000000a1;
public int RESOURCE_MISSING = 0x000000a2;
public int METHOD_NOT_FOUND = 0x000000a3;
public int FRAMEWORK_ERROR = 0x000000b1;
public int UNKNOWN = 0x000000ff;
#endregion
public string getName(int CODE)
{
}
I would like to get the value string
from a parameter CODE
, in a function getName
.
How can i do this?

Good C # practice is to use an enum:
public enum ErrorCode
{
NORMAL_STOP = 0x00000000,
LIB_BROKEN = 0x000000a1,
RESOURCE_MISSING = 0x000000a2,
METHOD_NOT_FOUND = 0x000000a3,
FRAMEWORK_ERROR = 0x000000b1,
UNKNOWN = 0x000000ff
}
public const string InvalidErrorCodeMessage = "Class not found";
public static string GetName(ErrorCode code)
{
var isExist = Enum.IsDefined(typeof(ErrorCode), code);
return isExist ? code.ToString() : InvalidErrorCodeMessage;
}
public static string GetName(int code)
{
return GetName((ErrorCode)code);
}
Another good tip, it would be great to use the C # naming convention for error codes:
public enum ErrorCode
{
NormalStop = 0x00000000,
LibBroken = 0x000000a1,
ResourceMissing = 0x000000a2,
MethodNotFound = 0x000000a3,
FrameworkError = 0x000000b1,
Unknown = 0x000000ff
}
Usage example:
void Main()
{
Console.WriteLine(GetName(0)); // NormalStop
Console.WriteLine(GetName(1)); // Class not found
Console.WriteLine(GetName(ErrorCode.Unknown)); // Unknown
}
