Convert string type number into Numeric value

Hi Pavneesh,

You may try the below code :

string number = "two hundred and two" ;

string[] words = number.ToLower().Split(new char[] {' ', '-', ','}, StringSplitOptions.RemoveEmptyEntries);

string[] ones = {"one", "two", "three", "four", "five", "six", "seven", "eight", "nine"};

string[] teens = {"eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen"};

string[] tens = {"ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety"};

System.Collections.Generic.Dictionary modifiers = new System.Collections.Generic.Dictionary() {

{"billion", 1000000000},

{"million", 1000000},

{"thousand", 1000},

{"hundred", 100}

};

int result = 0;

int currentResult = 0;

int lastModifier = 1;

foreach(string word in words) {

if(modifiers.ContainsKey(word)) {

lastModifier *= modifiers[word];

} else {

int n;

if(lastModifier > 1) {

result += currentResult * lastModifier;

lastModifier = 1;

currentResult = 0;

}

if((n = Array.IndexOf(ones, word) + 1) > 0) {

currentResult += n;

} else if((n = Array.IndexOf(teens, word) + 1) > 0) {

currentResult += n + 10;

} else if((n = Array.IndexOf(tens, word) + 1) > 0) {

currentResult += n * 10;

} else if(word != "and") {

throw new ApplicationException("Unrecognized word: " + word);

}

Console.WriteLine(result + currentResult * lastModifier);

Output : 202

Thanks,
