私はVisual Studio 2015とC＃を使用しています。私はレジデンスタイプに基づいてクレジットを計算しようとしています。計算とゲッターとセッターを持つクラスがあります。しかし、計算をクリックすると、合計として0が表示されます。明らかに、物事は正しく接続されていません。しかし、私はどこでこれを解決するかについては不明です。C＃クラス内で計算する
これは私のクラスファイルです：
namespace QuarterTuition
{
class Business
{
private int creditsTotal;
private int creditsPriceGuide;
public static double FullCost;
public Business(int credits, string residency)
{
creditsTotal = credits;
Residency = residency;
}
public double FullPrice
{
get { return FullCost; }
}
// Checking that credits is greater than zero
public static bool IsValidCreditAmount(int testValue)
{
return testValue > 0;
}
// Method for getting and setting Credit Totals.
public int CreditsTotal
{
get { return creditsTotal; }
set
{
if (IsValidCreditAmount(value))
{
creditsTotal = value;
}
else
{
throw new ApplicationException("Invalid! Credits must be greater than zero.");
}
}
}
// Method for determining which pricing section the credit amount is in.
public int CreditAmountSection
{
get { return creditsTotal; }
set
{
if (creditsTotal <= 10)
{
creditsPriceGuide = 1;
}
if (creditsTotal > 10 && creditsTotal <= 18)
{
creditsPriceGuide = 2;
}
if (creditsTotal > 18)
{
creditsPriceGuide = 3;
}
else
{
throw new ApplicationException("Invalid Credit Amount!");
}
}
}
// Checking that the string is empty
public static bool IsEmptyString(string testValue)
{
return testValue == "";
}
// Checking that the residency is not an empty string
public static bool IsValidResidency(string testValue)
{
return !IsEmptyString(testValue);
}
//variable
private string residentType;
// Method to check Residency Type
public string Residency
{

residentType = value;

public void ResidentCreditCost()
{

}
、これが私の計算ボタンです：
private void btnCalculate_Click(object sender, EventArgs e)
{
int credits = Convert.ToInt16(tbCredits.Text);
string residency = "";
if (rbResident.Checked == true)
{
residency = "Resident";
}
if (rbNResUS.Checked == true)
{
residency = "NResUS";
}
if (rbNResNUS.Checked == true)
{
residency = "NResNUS";
}
Business bus = new Business(credits, residency);
double totalComplete = bus.FullPrice;
// Test that it is obtaining the credits
tbTotal.Text = Convert.ToString(totalComplete);
// End Test
}
私は私の計算がTextBoxで、総授業料を発生して表示してもらうにはどうすればよいですか？
