Ich verwende Visual Studio 2015 und C#. Ich versuche Credits basierend auf dem Residency-Typ zu berechnen. Ich habe eine Klasse, die die Berechnungen und Getters und Setter hat. Wenn ich jedoch auf Berechnen klicke, wird nur 0 als Summe angezeigt. Offensichtlich verbinden sich die Dinge nicht richtig. Ich bin mir jedoch nicht sicher, wo oder wie ich das beheben kann.C# Innerhalb einer Klasse berechnen
Dies ist meine Klassendatei:
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
{
get { return residentType; }
set
{
if (IsValidResidency(value))
residentType = value;
else
throw new ApplicationException("Invalid Residency");
}
}
// 1-10 CREDITS
// Cost for 1-10 Credits
const double Resident110 = 104.11;
const double NResUS110 = 117.11;
const double NResNUS110 = 276.11;
// 11-18 CREDITS
// Cost for 11-18 Credits
const double Resident118Base = 1041.10;
const double NResUS1118Base = 1171.10;
const double NResNUS1118Base = 2761.10;
// Cost for each credit 11-18
const double Resident11218 = 51.40;
const double NResUS11218 = 52.09;
const double NResNUS11218 = 56.41;

// Cost for 19+ Credits
const double Resident18Base = 1452.30;
const double NResUS18Base = 1587.82;
const double NResNUS18Base = 3212.38;
// Cost for each credit beyond 18
const double Resident18More = 96.26;
const double NResUS18More = 96.26;
const double NResNUS18More = 268.26;
/// <summary>
/// CALCULATIONS BELOW

public void ResidentCreditCost()
{
int credits = CreditAmountSection;
int credSection = CreditAmountSection;
string resType = Residency;
if (resType == "Resident")
{
if (credSection == 1)
{
FullCost = Resident110 * credits;
}
if (credSection == 2)
{
double temp = Resident118Base * 10;
int tempCred = credits - 10;
double tempAdditional = tempCred * Resident11218;
FullCost = temp + tempAdditional;
}
if (credSection == 3)
{

}
}
}
public void NonResidentUSCreditCost()
{
int credits = CreditAmountSection;
int credSection = CreditAmountSection;
string resType = Residency;
if (resType == "NResUS")
{
if (credSection == 1)
{

}
if (credSection == 2)
{

}
if (credSection == 3)

}
}
public void NonResidentNUSCreditCost()

int credSection = CreditAmountSection;
string resType = Residency;

int tempCred = credits - 18;
double tempAdditional = tempCred * NResNUS18More;
FullCost = temp + tempAdditional;
}
}
}
}
}
und dies ist meine Schaltfläche berechnen:
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
}
Wie erhalte ich meine Berechnungen den Gesamtunterricht in den TextBox auftreten und zeigen?

Hallo, siehe [Erstellen eines minimalen, vollständigen und überprüfbaren Beispiels] (http://stackoverflow.com/help/mcve). Es ist einfacher, dir zu helfen, wenn es nicht so viel Code gibt. :) – smead
Ich rate, es nicht zu setzen Ihre CreditsTotal zu einem Wert sein – BugFinder
