Question

For this question, assume you are working on C# code in which you have already created an event handler method named btnCalculate_Click that contains a decimal variable named itemPrice. Paste or type into the space provided the following C# code:

1. The code for creating a private method named CalculateContractPrice that receives the itemPrice and uses it to calculate and return a decimal value that represents the price of the extended service contract that our company offers. Our company prices the service contracts as follows:

For an item with an itemPrice less than $100 the two year service contract price is $19.

For an item with an itemPrice from $100 to $299.99 the two year service contract price is $39.

For an item with an itemPrice greater than $299.99 the two year service contract price is 15% of the itemPrice.

2. The line(s) of code you need to add to the btnCalculate_Click event handler method to call the CalculateContractPrice method and place the value it returns into a variable named serviceContractPrice (assume this variable has already been declared).

Code

using System;

using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace CheggSpace
{
public partial class ContractPrice : System.Web.UI.Page
{
decimal itemPrice = 0.0M;
decimal serviceContract = 0.0M;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
}
}

protected void btnCalculate_Click(object sender, EventArgs e)
{
txtServiceContractPrice.Text = "";
serviceContract = CalculateContractPrice(Decimal.Parse(txtItemPrice.Text));
txtServiceContractPrice.Text = "$"+ Convert.ToString(serviceContract);
}
private decimal CalculateContractPrice(decimal itemPrice)
{
decimal serviceContract = 0.0M;
if (itemPrice < 100.00M)
{
serviceContract = 19*itemPrice;
}
else if (itemPrice >= 100.00M && itemPrice <= 299.99M)
{
serviceContract = 39*itemPrice;
}
else if (itemPrice > 299.99M)
{
serviceContract = 15*itemPrice;
}
return serviceContract;
}
}
}

Note: I create .aspx page i.e Web Form

it consists of Design and Code , i consider CalculateContractPrice(decimal itemPrice)

i took two text boxes i.e txtItemPrice accepts item price and txtServiceContractPrice gives result.

and btnCalculate click gives result to us.

I use C# Framework 4.5 ,if any queries or help , send comments
