[c#] How to format string to money

I have a string like 000000000100, which I would like to convert to 1.00 and vice versa.

Leading zero will be remove, last two digit is the decimal.

I give more example :

000000001000 <=> 10.00
000000001005 <=> 10.05
000000331150 <=> 3311.50

Below is the code I am trying, it is giving me result without decimal :

amtf = string.Format("{0:0.00}", amt.TrimStart(new char[] {'0'}));

decimal value = 0.00M;
value = Convert.ToDecimal(12345.12345);
Console.WriteLine(value.ToString("C"));
//OutPut : $12345.12
Console.WriteLine(value.ToString("C1"));
//OutPut : $12345.1
Console.WriteLine(value.ToString("C2"));
//OutPut : $12345.12
Console.WriteLine(value.ToString("C3"));
//OutPut : $12345.123
Console.WriteLine(value.ToString("C4"));
//OutPut : $12345.1234
Console.WriteLine(value.ToString("C5"));
//OutPut : $12345.12345
Console.WriteLine(value.ToString("C6"));
//OutPut : $12345.123450

Console output:

var tests = new[] {"000000001000", "000000001005", "000000331150"};
foreach (var test in tests)
{
    Console.WriteLine("{0} <=> {1:f2}", test, Convert.ToDecimal(test) / 100);
}

Since you didn't ask for the currency symbol, I've used "f2" instead of "C"

It works!

decimal moneyvalue = 1921.39m; 
string html = String.Format("Order Total: {0:C}", moneyvalue); 
Console.WriteLine(html);

Output

Order Total: $1,921.39

try

amtf =  amtf.Insert(amtf.Length - 2, ".");

    string s ="000000000100";
    decimal iv = 0;
    decimal.TryParse(s, out iv);
    Console.WriteLine((iv / 100).ToString("0.00"));

Once you have your string in a double/decimal to get it into the correct formatting for a specific locale use

double amount = 1234.95;

amount.ToString("C") // whatever the executing computer thinks is the right fomat

amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-ie"))    //  €1,234.95
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("es-es"))    //  1.234,95 € 
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-GB"))    //  £1,234.95 

amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-au"))    //  $1,234.95
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-us"))    //  $1,234.95
amount.ToString("C", System.Globalization.CultureInfo.GetCultureInfo("en-ca"))    //  $1,234.95

//Extra currency symbol and currency formatting: "€3,311.50":
String result = (Decimal.Parse("000000331150") / 100).ToString("C");

//No currency symbol and no currency formatting: "3311.50"
String result = (Decimal.Parse("000000331150") / 100).ToString("f2");

you will need to convert it to a decimal first, then format it with money format.

EX:

decimal decimalMoneyValue = 1921.39m;
string formattedMoneyValue = String.Format("{0:C}", decimalMoneyValue);

a working example: https://dotnetfiddle.net/soxxuW

Try something like this:

decimal moneyvalue = 1921.39m;
string html = String.Format("Order Total: {0:C}", moneyvalue);
Console.WriteLine(html);

Try simple like this

 var amtf = $"{Convert.ToDecimal(amt):#0.00}";

Parse to your string to a decimal first.

you can also do :

string.Format("{0:C}", amt)
