Convert string to decimal to string and back to decimal

Question

I want to convert a string to a decimal then to a string and then to a decimal again.

I tried:

Dim s As String = "0.7655"

CDec(sDec).ToString("0.00")  'results in: 7653,00
CDec(sDec).ToString 'results in: 7648
CDec(sDec).ToString("N") 'results in: 7.653,00

So none of these work!

Is there no easy function to just convert the exact decimal to its string representation again? Seems like too much work for such a simple task!

Preferably without formatting the string, because in that case I seem to know beforehand how many characters the resulting string should have. After converting it to string, I also want to convert it back to a decimal again.

Solution

In your current culture the decimal separator might be a comma instead of a dot. Using the invariant culture will always use the dot:

Dim s As String = "0.7655"

Dim decValue As Decimal = Decimal.Parse(s, System.Globalization.CultureInfo.InvariantCulture)
Console.WriteLine(decValue.ToString())
