Convert string value to decimal with thousand separator?

Question

This might be a very simple question. Suppose text box show value 10,000.12 when user edits data by mistake he remove first two numbers like ,000.12 and using this textbox in t

Answer 1

This is pretty messed up and I am not sure if all of you strings will look the same, but in case they do this might do the trick:

string str = ",0,100.12";
decimal number;
bool converted = decimal.TryParse(str.Substring(str.LastIndexOf(",") + 1), out number);

The variable converted will tell you whether or not your string was converted and you will not an exception.

Good luck!

Answer 2

string a = "100.12";
decimal b = Convert.ToDecimal(a);

Answer 3

string str = ",0,100.12;";
var newstr = Regex.Replace(str,@"[^\d\.]+","");
decimal d = decimal.Parse(newstr, CultureInfo.InvariantCulture);

Answer 4

If I understood the question, you want to remove all characters that would prevent the parse routine from failing.

string str = ",0,100.12";

var modified = new StringBuilder();
foreach (char c in str)
{
    if (Char.IsDigit(c) || c == '.')
        modified.Append(c);
}

decimal number= decimal.Parse(modified.ToString());
