convert currency formatted string to decimal in csharp

You can convert a currency formatted string to decimal in C# by using the decimal.Parse or decimal.TryParse methods, along with specifying the correct format provider.

Here's an example:

main.cs
string currencyString = "$1,234.56";
decimal amount;

// Using decimal.Parse
amount = decimal.Parse(currencyString, System.Globalization.NumberStyles.Currency);

// Using decimal.TryParse
if (decimal.TryParse(currencyString, System.Globalization.NumberStyles.Currency, null, out amount))
{
    // Conversion successful
    Console.WriteLine("Amount: " + amount);
}
else
{
    // Conversion failed
    Console.WriteLine("Invalid currency format");
}

In this example, the currencyString variable contains the currency formatted string. The decimal variable amount is used to store the converted value.

Both decimal.Parse and decimal.TryParse methods allow you to specify the NumberStyles.Currency style to handle currency-specific formatting. This includes handling currency symbols, decimal separators, and group separators according to the current culture settings.

If the conversion is successful, the amount variable will contain the decimal value. Otherwise, if the conversion failed (e.g., due to an invalid format), an appropriate error message can be displayed.

Remember to include the necessary namespaces for the code to compile successfully.

Note: This method assumes that the currency string is in the format expected by the current culture settings. If the string is in a different format, you may need to specify a specific culture or modify the code accordingly.
