string []A=new string[]{"零","一","二","三","四","五","六","七","八","九"};
string []B=new string[]{"分","角","圆","十","百","千","万","十","百","千","亿","十","百","千"};

double Val = 113465.98;
int X =(int)( Val * 100 );
string ChnStr ="";

int index=0;

while(X>0)
{
int v = X%10;
ChnStr = A[v]+B[index++]+ChnStr;
X = X/10;
}
Console.WriteLine( ChnStr );
