Custom Currency symbol and decimal places using decimal.ToString("C") and CultureInfo

Question

I have a problem with decimal.ToString("C") override. Basically what I wants to do is as follows:

CultureInfo usCulture = new CultureInfo("en-US");
Thread.CurrentThread.CurrentCulture = usCulture;

NumberFormatInfo LocalFormat = (NumberFormatInfo)NumberFormatInfo.CurrentInfo.Clone();
LocalFormat.CurrencySymbol = "RM";

I wants to make above code a function (override ToString("C")) whereby when the following code get executed:

decimal paid = Convert.ToDecimal(dr["TotalPaids"]);
lblPaids.Text = paid.ToString("C");

The results would be RM4,900.00 instead of $4,900.00

How do I create an override for decimal.ToString("C") that would solve my problem

Thanks in advance.

Answer 1

To get a format like RM 11,123,456.00 you also need to set the following properties

CurrentCulture modified = new CultureInfo(Thread.CurrentThread.CurrentCulture.Name);
Thread.CurrentThread.CurrentCulture = modified;
var numberFormat = modified.NumberFormat;
numberFormat.CurrencySymbol = "RM";
numberFormat.CurrencyDecimalDigits = 2;
numberFormat.CurrencyDecimalSeparator = ".";
numberFormat.CurrencyGroupSeparator = ",";

If you do that at application startup then that should make ms-MY format like en-US but with the RM currency symbol every time you call the ToString("C") method.
