    } 
    catch (System.InvalidCastException) {
        System.Console.WriteLine(
            "Char-to-decimal conversion is not supported " +
            "by the framework.");
    }

    try {
        charVal = System.Convert.ToChar(decimalVal);
    } 
    catch (System.InvalidCastException) {
        System.Console.WriteLine(
            "Decimal-to-char conversion is not supported " +
            "by the framework.");

public void ConvertCharDecimal(char charVal)
