How would I make a Parse Currency Function?

Hey,

I'm a noob programmer so this is likely to be off the mark, but at-least I can do a bit of learning and maybe even help the odd person if I pickup any questions that I think I can answer.

I'm not sure what you're trying to do but I knocked this up, if it's that you're trying to define your own custom abbreviations for stuff. I think that c# uses decimal for currency, else I'd have tried to work in generics, which I've been learning.

Somebody will likely come along and wipe this away in one line of code, but that gives me a chance to learn too!

public static decimal ParseCurrency(string Value)
{
//dictionary to hold abbreviations
Dictionary<char, string> _abbreviationMap = new Dictionary<char, string>();
//add some abbreviations
_abbreviationMap.Add('M', "00000");
_abbreviationMap.Add('K', "00");
_abbreviationMap.Add('X',"00000000");

//validate Value
if (!_abbreviationMap.ContainsKey(Value.Last()))
{
throw new Exception(string.Format("{0} is not an acceptable abbreviation.", Value.Last()));
}

//try parse
decimal _result = new decimal();
if (decimal.TryParse(Value.Substring(0, Value.Length - 1) + _abbreviationMap[Value.Last()], out _result))
{
return _result;
}
else
{
throw new Exception(string.Format("{0} could not be parsed."));
}
}
