C# string to decimal error

Question

I'm having trouble with a very simple problem. Basically I'm taking a string, like "$30.00", and removing the '$' and then trying to convert it to a decimal. Although I keep getting an error stating that the string isn't in the correct format. Not sure what to do from here...

string freightstart = PostFregihtAmount.ToString();

freightstart = freightstart.TrimStart('$');

decimal freight = Decimal.Parse(freightstart);

I tried the following, per Alex Skiba's suggestion in the comments:

Decimal.Parse(freightstart, System.Globalization.CultureInfo.InvariantCulture);

This is the error I receive upon debugging:

This is a plugin for our onsite CRM 2011 system and some fields that I have to reference on the quote form are currency fields. When I query the data they come back as string formats, hence the example "$30.00". Long story short I need to convert it to decimal so that I may do my tax solution.

Probably you have localization issue here. Your regional settings are different from the input format. Try Decimal.Parse(freightstart, System.Globalization.CultureInfo.InvariantCulture); If it will help, read something about localization. — Alex Skiba

stupid to close the question as it's a real problem as @AlexSkiba stated — adjan

Try explicitly allowing the decimal point when you parse the string, as well as the currency symbol (then you don't have to trim the $ before parsing):

var freight = Decimal.Parse("$30.00",
              NumberStyles.AllowCurrencySymbol | NumberStyles.AllowDecimalPoint);
