converting to currecny and decimal

Question

    decTotalCost = intNumDays * decLocationFee + decRegistrationFee
    lstCost.Items.Add(decTotalCost).ToString("c")

in the statement above, the right amount is sent to lstCost, but not as a ("c") or a decimal, any suggestions?

Answer 1

Is this what you want? Note how I've done the format without ToString.

private void button1_Click(object sender, EventArgs e)  
{  
    int intNumDays = 8;  
    decimal decLocationFee = 23.77m;  
    decimal decRegistrationFee = 12.99m;  
      
    decimal decTotalCost = intNumDays * decLocationFee + decRegistrationFee;  
    lstCost.Items.Add($"{decTotalCost:C}");  
}  

Answer 2

Hi @Hekzdaddy ,

the right amount is sent to lstCost, but not as a ("c") or a decimal,

Change :
lstCost.Items.Add(decTotalCost).ToString("c")
To:
lstCost.Items.Add(decTotalCost.ToString("c"))

Best Regards,
