问题
I have windows application in which i need to convert amount entered in text-box into the words in ruppes and paise format.
for e.g My amount is 2356.54 then it should display two thousand three hundred fifty six ruppes and fifty four paise only however, i have code that convert amt to words but i am not able to show paise.i am including my code for reference purpose.
private void btntowords_Click(object sender, EventArgs e)
{
MessageBox.Show( words(Convert.ToInt32(textBox1.Text)));
}
public string words(int numbers)
{
int number = numbers;
if (number == 0) return "Zero";
if (number == -2147483648) return "Minus Two Hundred and Fourteen Crore Seventy Four Lakh Eighty Three Thousand Six Hundred and Forty Eight";
int[] num = new int[4];
int first = 0;
int u, h, t;
System.Text.StringBuilder sb = new System.Text.StringBuilder();
if (number < 0)
{
sb.Append("Minus ");
number = -number;
}
string[] words0 = {"" ,"One ", "Two ", "Three ", "Four ",
"Five " ,"Six ", "Seven ", "Eight ", "Nine "};
string[] words1 = {"Ten ", "Eleven ", "Twelve ", "Thirteen ", "Fourteen ",
"Fifteen ","Sixteen ","Seventeen ","Eighteen ", "Nineteen "};
string[] words2 = {"Twenty ", "Thirty ", "Forty ", "Fifty ", "Sixty ",
"Seventy ","Eighty ", "Ninety "};
string[] words3 = { "Thousand ", "Lakh ", "Crore " };
num[0] = number % 1000; // units
num[1] = number / 1000;
num[2] = number / 100000;
num[1] = num[1] - 100 * num[2]; // thousands
num[3] = number / 10000000; // crores
num[2] = num[2] - 100 * num[3]; // lakhs
for (int i = 3; i > 0; i--)
{
if (num[i] != 0)
{
first = i;
break;
}
}
for (int i = first; i >= 0; i--)
{
if (num[i] == 0) continue;
u = num[i] % 10; // ones
t = num[i] / 10;
h = num[i] / 100; // hundreds
t = t - 10 * h; // tens
if (h > 0) sb.Append(words0[h] + "Hundred ");
if (u > 0 || t > 0)
{
if (h > 0 || i == 0) sb.Append("and ");
if (t == 0)
sb.Append(words0[u]);
else if (t == 1)
sb.Append(words1[u]);
else
sb.Append(words2[t - 2] + words0[u]);
}
if (i != 0) sb.Append(words3[i - 1]);
}
return sb.ToString().TrimEnd();
}
It should not show pasie if it has amount like this 2356.00
so i have tried by many ways to get paise but not succeed. i have tried ggogle but not getting exactly what i want.
回答1:
You need to separate the decimal number and get two separate values one before decimal place and one after it. For example in 56.2 you get 56 separately and 2 separately and call you words() function for both of them. You'll get two strings one "Fifty six" and second "two". You can join these strings to say "Fifty six rupee 2 paisas".

You need small change in your method. Please find below method
public string words(double? numbers, Boolean paisaconversion = false)
{
var pointindex = numbers.ToString().IndexOf(".");
var paisaamt = 0;
if (pointindex > 0)
paisaamt = Convert.ToInt32( numbers.ToString().Substring(pointindex + 1, 2));
int number = Convert.ToInt32( numbers);
if (number == 0) return "Zero";
if (number == -2147483648) return "Minus Two Hundred and Fourteen Crore Seventy Four Lakh Eighty Three Thousand Six Hundred and Forty Eight";
int[] num = new int[4];
int first = 0;
int u, h, t;
System.Text.StringBuilder sb = new System.Text.StringBuilder();
if (number < 0)
{
sb.Append("Minus ");
number = -number;
}
string[] words0 = {"" ,"One ", "Two ", "Three ", "Four ","Five " ,"Six ", "Seven ", "Eight ", "Nine "};
string[] words1 = {"Ten ", "Eleven ", "Twelve ", "Thirteen ", "Fourteen ","Fifteen ","Sixteen ","Seventeen ","Eighteen ", "Nineteen "};
string[] words2 = {"Twenty ", "Thirty ", "Forty ", "Fifty ", "Sixty ","Seventy ","Eighty ", "Ninety "};
string[] words3 = { "Thousand ", "Lakh ", "Crore " };
num[0] = number % 1000; // units
num[1] = number / 1000;
num[2] = number / 100000;
num[1] = num[1] - 100 * num[2]; // thousands
num[3] = number / 10000000; // crores
num[2] = num[2] - 100 * num[3]; // lakhs
for (int i = 3; i > 0; i--)
{
if (num[i] != 0)
{
first = i;
break;
}
}
for (int i = first; i >= 0; i--)
{
if (num[i] == 0) continue;
u = num[i] % 10; // ones
t = num[i] / 10;
h = num[i] / 100; // hundreds
t = t - 10 * h; // tens
if (h > 0) sb.Append(words0[h] + "Hundred ");
if (u > 0 || t > 0)
{
if (h > 0 || i == 0) sb.Append("and ");
if (t == 0)
sb.Append(words0[u]);
else if (t == 1)
sb.Append(words1[u]);
else
sb.Append(words2[t - 2] + words0[u]);
}
if (i != 0) sb.Append(words3[i - 1]);
}
if (paisaamt == 0 && paisaconversion == false)
{
sb.Append("ruppes only");
}
else if (paisaamt > 0)
{
var paisatext = words(paisaamt, true);
sb.AppendFormat("rupees {0} paise only", paisatext);
}
return sb.ToString().TrimEnd();
}

Give input as number upto 999999999 the output will be in words.

string[] words0 = { "Zero ", "One ", "Two ", "Three ", "Four ", "Five ", "Six ", "Seven ", "Eight ", "Nine ", "Ten ", "Eleven ", "Twelve ", "Thirteen ", "Fourteen ", "Fifteen ", "Sixteen ", "Seventeen ", "Eighteen ", "Nineteen ", "Twenty " };
