Regex Error in currency

问题

I have a big problem, I used this codes to generate the number to currency,

Dim reg = New Regex("\d+")
Dim str As String = dZ.Rows(y).Item(14).ToString().Replace(",", ""). _
                               Replace(".00", "").Replace("$", "").Trim
Dim match = reg.Match(str)
If match.Success Then
    str = reg.Replace(str, Decimal.Parse(match.Value).ToString("C"))
End If

yes it works, but what if my amount is:

1,900.50 POC

kelvzy your solution is not very flexible. I will suggest my solution:

string cellValue = dZ.Rows[y][14];
string cleanedCellValue = Regex.Replace(s, @"\s[^\d.,]+", ""); 
//this will replace everything after the last digit

string decimalValue = Convert.ToDecimal(cleanedCellValue, CultureInfo.InvariantCulture);
string str = decimalValue.ToString("C");

This solution will work, when each cell uses comma as thousand separator, dot as decimal separator and any symbols as currency symbol.

In other case give me please more examples
