hashTable.Add("two", "2");
hashTable.Add("three", "3");
hashTable.Add("four", "4");
hashTable.Add("five", "5");

hashTable.Add("thousand", "1000");
hashTable.Add("lakh", "100000");
hashTable.Add("crore", "10000000");
string wordValue = TextBox1.Text.Trim().ToLower();
string[] strArray = wordValue.Split(' ');
int value = 0;
int tempValue = 0;
foreach (string s in strArray)
{
if (object.Equals(s, "hundred") || object.Equals(s, "thousand") || object.Equals(s, "lakh") || object.Equals(s, "crore"))
{
value += tempValue * int.Parse(hashTable[s].ToString());
tempValue = 0;
}
else
{
if (hashTable.ContainsKey(s))
{
tempValue += int.Parse(hashTable[s].ToString());
}
}
}
TextBox1.Text = (value + tempValue).ToString();
}
