一般情况下的格式处理并不需要太多的考虑，甚至c\#还有自动处理格式的方法。。。当然有些时候也会用到自己处理格式的情况，以下就是方法：

internal static class CommonFormater
        {
            internal static bool TryParselong(string val, out long? result)
            {
                long outValue;
                if (long.TryParse(val, out outValue))
                {
                    result = (long?)outValue;
                    return true;
                }
                result = null;
                return false;
            }
            internal static long? TryParselong(string val)
            {
                long outValue;
                if (long.TryParse(val, out outValue))
                {
                    return (long?)outValue;
                }
                return null;
            }
            internal static decimal? TryParseDecimal(string val)
            {
                decimal outValue;
                if (decimal.TryParse(val, out outValue))
                {
                    return (decimal?)outValue;
                }
                return null;
            }
            internal static bool TryParseDecimal(string val, out decimal? result)
            {
                decimal outValue;
                if (decimal.TryParse(val, out outValue))
                {
                    result = (decimal?)outValue;
                    return true;
                }
                result = null;
                return false;
            }
            internal static bool TryParseInt(string val, out int? result)
            {
                int outValue;
                if (int.TryParse(val, out outValue))
                {
                    result = (int?)outValue;
                    return true;
                }
                result = null;
                return false;
            }
            internal static bool TryParseDatetime(string val, out DateTime? result)
            {
                DateTime outValue;
                System.IFormatProvider format = new System.Globalization.CultureInfo("zh-CN", true);
                if (DateTime.TryParse(val, format, System.Globalization.DateTimeStyles.None, out outValue))
                {
                    result = (DateTime?)outValue;
                    return true;
                }
                result = null;
                return false;
            }
        }
