我如何獲得數組循環，以便公式增加，如每月付款

好我的問題更簡單，這次我已經重做我以前的問題的代碼。現在我試圖弄清楚爲什麼我的每月賬單沒有增加。它應該在方程中增加。我嘗試調試代碼，但沒有發現ArrayMonths數組是否循環。我如何獲得數組循環，以便公式增加，如每月付款

private void CalculateButton_Click(object sender, EventArgs e) 
{ 
string[] ArrayModel ={"CAMERO","IMPALA","TAHOE","SILVERADO","MUSTANG","TAURUS","EXPEDITION","F150", 
          "CAMERY","COROLLA","HIGHLANDER","TUNDRA","CHALLENGER","DART","DURANGO","RAM"}; 
double[] ArrayPrice ={33809,23300,49601,33383, 40585,32500,36245,46905, 
         48050,32560,42580,47530, 27995,20150,39750,45620}; 
double[] ArrayMonths = { 36, 48, 60, 72 }; 

string Model = ModelBox.Text.ToUpper(); 
double InterestRate = 0, TotalIntrst, MonthlyBill, Multiplier, Year, MaxYear = 4; 
string UsrModelVehicle = ModelBox.Text.ToUpper(); 
double UsrScrInpt = Convert.ToDouble(CreditScoreBox.Text); 
{ 
     if (UsrScrInpt <= 450) 
    { 
     for (int x = 0; x < ArrayModel.Length; ++x) 
     { 
      if (Model == ArrayModel[x]) 
      { 
       foreach (double Months in ArrayDuration) 
       { 
        ArrayModel[x] = Convert.ToString(ArrayLoan[x]); 
        InterestRate = 0.12; 
        TotalIntrst = InterestRate/1200; 
        MonthlyBill = ArrayLoan[x] * TotalIntrst/(1 - (Math.Pow(1/(1 + TotalIntrst), Months))); 

        UserMonthlyPayLabel.Text += string.Format("{0:C2}\n", MonthlyBill); 
        UserInterestLabel.Text = string.Format("{0:P2}", InterestRate); 
        InterestLabel.Text = string.Format("Interest"); 
        PayNumbersLabel.Text = string.Format("36\n48\n60\n72\n");

確定型號從文本框是數組中？ –

ArrayMonths [y]是我試圖循環以提高月數，這將增加* MonthlyBill *，然後反過來給我我的名單。我認爲。我希望。 – Brandonl29

你是什麼意思列表不增加？你期望看到什麼？您是否希望每次迭代for循環都更新標籤文本？因爲這不是一個很好的實現。 –

private void ReloadForm()//Here is the new method I was talking about. 
{ 
UserMonthlyPayLabel.ResetText(); 
    //this will reset the label I need for it to clear after change the model. 
} 
private void CalculateButton_Click(object sender, EventArgs e) 
    { 
    DetailsGroup.Visible = true; 
    PaymentGroup.Visible = true;

    double UsrScrInpt = Convert.ToDouble(CreditScoreBox.Text); 
    ReloadForm(); 
//Here is where I call it to reset the label. It works pretty good. 
    { 
    if (UsrScrInpt <= 450)
