C# Translate Numeric Values in Words upto 99lacs including decimals

Use NUM_IN_WORDS function where u want to Translate numeric values in words. Pass numeric value in function it returns string as in words. eg. NUMBER: 2134 ANSWER: Two Thousand One Hundred Thirty Four. Its limit is upto 99Lacs with decimals

public string Num_In_Words(string str_Num) {
// Function to convert numerical value in words
string One_Ch="";
string Chk_Pos="";
string temp="";
string Paise="";
string Rupees="";
string Temp1;
string Num_In_Words="";
int ZeroErr=0;
int DOT=0;
int i;
i = 1;
// temp = str_Num
Paise = "";
Temp1 = "";
for (int L = 1; (L <= str_Num.Length); L++) { Temp1 = str_Num.Substring((L - 1), 1); if ((Temp1 == ".")) { DOT = 1; } else if ((DOT != 1)) { Rupees = (Rupees + Temp1); } else { Paise = (Paise + Temp1); } } // For Rupees temp = Rupees; while ((temp.Length != 0)) { One_Ch = Rupees.Substring((i - 1), 1); // Detecting tens of the number if ((One_Ch != "0")) { switch (temp.Length) { case 7: Num_In_Words = (Num_In_Words + Conv_Word(One_Ch, 7, temp.Substring(1, 1))); Chk_Pos = One_Ch; break; case 6: if ((Chk_Pos == "1")) { Num_In_Words = (Num_In_Words + " Lakhs "); ZeroErr = 1; } else { Num_In_Words = (Num_In_Words + (Conv_Word(One_Ch, 6, "") + " Lakhs ")); ZeroErr = 1; } break; case 5: Num_In_Words = (Num_In_Words + (Conv_Word(One_Ch, 5, temp.Substring(1, 1)) + " ")); Chk_Pos = One_Ch; break; case 4: if ((Chk_Pos == "1")) { Num_In_Words = (Num_In_Words + " Thousand "); } else { Num_In_Words = (Num_In_Words + (Conv_Word(One_Ch, 4, "") + " Thousand ")); } break; case 3: Num_In_Words = (Num_In_Words + (Conv_Word(One_Ch, 3, "") + " Hundred ")); Chk_Pos = ""; break; case 2: Num_In_Words = (Num_In_Words + (Conv_Word(One_Ch, 2, temp.Substring(1, 1)) + " ")); Chk_Pos = One_Ch; break; case 1: if ((Chk_Pos != "1")) { Num_In_Words = (Num_In_Words + Conv_Word(One_Ch, 1, "")); } break; switch (temp.Length) { case 6: if ((temp.Substring(0, 1) == "0")) { Num_In_Words = (Num_In_Words + " Lakhs "); } break; case 4: if ((temp.Substring(0, 1) == "0")) { Num_In_Words = (Num_In_Words + " Thousand "); } break; } } } i = (i + 1); if (Rupees.Length > 0)
