Answer 1

public static string CmycurD(decimal num)
{
string str1 = "零壹贰叁肆伍陆柒捌玖"; //0-9所对应的汉字
string str2 = "万仟佰拾亿仟佰拾万仟佰拾元角分"; //数字位所对应的汉字
string str3 = ""; //从原num值中取出的值
string str4 = ""; //数字的字符串形式
string str5 = ""; //人民币大写金额形式
int i; //循环变量
int j; //num的值乘以100的字符串长度
string ch1 = ""; //数字的汉语读法
string ch2 = ""; //数字位的汉字读法
int nzero = 0; //用来计算连续的零值是几个
int temp; //从原num值中取出的值

num = Math.Round(Math.Abs(num),2); //将num取绝对值并四舍五入取2位小数
str4 = ((long)(num*100)).ToString(); //将num乘100并转换成字符串形式
j = str4.Length; //找出最高位
if (j > 15){return "溢出";}
str2 = str2.Substring(15-j); //取出对应位数的str2的值。如：200.55,j为5所以tr2=佰拾元角分

//循环取出每一位需要转换的值
for(i=0;i<j;i++)
{
str3 = str4.Substring(i,1); //取出需转换的某一位的值
temp = Convert.ToInt32(str3); //转换为数字
if (i != (j-3) && i != (j-7) && i != (j-11) && i != (j-15))
