The following code sample illustrates the use of ToDecimal, by attempting to convert a String to a Decimal and throwing any of the possible exceptions that may arise during the conversion.
public void ConvertStringDecimal(string stringVal) { decimal decimalVal = 0; try { decimalVal = System.Convert.ToDecimal(stringVal); outputBlock.Text += String.Format( "The string as a decimal is {0}.", decimalVal) + "\n"; } catch (System.OverflowException) { outputBlock.Text += String.Format( "The conversion from string to decimal overflowed.") + "\n"; } catch (System.FormatException) { outputBlock.Text += String.Format( "The string is not formatted as a decimal.") + "\n"; } catch (System.ArgumentNullException) { outputBlock.Text += String.Format( "The string is null.") + "\n"; } // Decimal to string conversion will not overflow. stringVal = System.Convert.ToString(decimalVal); outputBlock.Text += String.Format( "The decimal as a string is {0}.", stringVal) + "\n"; }
