        // Example value
        decimal amount = 1234.5678M; // Replace this with your actual value

        // Round off to the nearest integer
        int roundedAmount = (int)Math.Round(amount);

        // Format as currency string
        string formattedAmount = roundedAmount.ToString("C");

        Console.WriteLine("Original Value: " + amount);
        Console.WriteLine("Rounded Value: " + roundedAmount);
        Console.WriteLine("Formatted Currency: " + formattedAmount);
    }
}
 

Try to use the ToString method with a format string. See the example

decimal amount = 1234.5678m; // Replace this with the currency amount
string currencySymbol = "$"; // Replace this with the desired currency symbol

int roundedAmount = (int)Math.Round(amount);

string formattedAmount = currencySymbol + roundedAmount.ToString("C");
Console.WriteLine(formattedAmount); // Output: $1,235.00

1. amount is the original currency amount (replace it with the value).
2. currencySymbol is the currency symbol you want to use (e.g., "$" for dollars).
