调用生成对应大写金额

decimal moneyVal = 23456.78M;
var capitalMoney = GetCapitalMoney(moneyVal);

string capitalVal = string.Format("{0}  拾   {1}  万   {2}  仟   {3}  佰   {4}  拾   {5}  元   {6}  角   {7}  分",
                    capitalMoney.MillionVal, capitalMoney.TenThousandVal
                    , capitalMoney.ThousandVal, capitalMoney.HundredVal
                    , capitalMoney.TenVal, capitalMoney.DollarVal
                    , capitalMoney.DimeVal, capitalMoney.MinVal);
Console.WriteLine(capitalVal);
Console.ReadKey();
