C# Check if a decimal has more than 3 decimal places?

Question

I have a situation that I cannot change: one database table (table A) accepts 6 decimal places, while a related column in a different table (table B) only has 3 decimal plac

Answer 1

Public Function getDecimalCount(decWork As Decimal) As Integer

    Dim intDecimalCount As Int32 = 0
    Dim strDecAbs As String = decWork.ToString.Trim("0")

    intDecimalCount = strDecAbs.Substring(strDecAbs.IndexOf(".")).Length -1

    Return intDecimalCount

End Function
