株式のリストボックスに表示される投資の名前を取得しようとしていますが、コード (プログラムで以前に使用したもの) が機能していないようです。
namespace JamesClemens_FinalProject
{
public partial class Form1 : Form
{
ArrayList account;
public Form1()
{
InitializeComponent();
account = new ArrayList();
}
//here we set up our add customer button from the first tab
//when the information is filled in and the button is clicked
//the name on the account will be put in the combobox on the second tab
private void btnAddCustomer_Click(object sender, EventArgs e)
{
try
{
CustomerAccount aCustomerAccount = new CustomerAccount(txtAccountNumber.Text, txtCustomerName.Text,
txtCustomerAddress.Text, txtPhoneNumber.Text);
account.Add(aCustomerAccount);
cboClients.Items.Add(aCustomerAccount.GetCustomerName());
ClearText();
}
catch (Exception)
{
MessageBox.Show("Make sure every text box is filled in!", "Error", MessageBoxButtons.OK);
}
}
private void ClearText()
{
txtAccountNumber.Clear();
txtCustomerName.Clear();
txtCustomerAddress.Clear();
txtPhoneNumber.Clear();
}
private void cboClients_SelectedIndexChanged(object sender, EventArgs e)
{
CustomerAccount custAccount = account[cboClients.SelectedIndex] as CustomerAccount;
if(custAccount != null)
{
txtAccountNumberTab2.Text = custAccount.GetAccountNumber();
txtCustomerNameTab2.Text = custAccount.GetCustomerName();
txtCustomerAddressTab2.Text = custAccount.GetCustomerAddress();
txtCustomerPhoneNumberTab2.Text = custAccount.GetCustomerPhoneNo();
}
}
これは私に問題を引き起こしているコードです。「new Stock」には4つの引数を取るコンストラクターが含まれていないと言い続けています。
private void btnAddStock_Click(object sender, EventArgs e)
{
try
{
Stock aStock = new Stock(txtInvestmentID.Text, txtInvestmentName.Text, txtInvestmentSymbol.Text,
int.Parse(txtInvestmentShares.Text));
account.Add(aStock);
lstStock.Items.Add(aStock.GetInvestmentName());
ClearText();
}
catch (Exception)
{
MessageBox.Show("Make sure every text box is filled in!", "Error", MessageBoxButtons.OK);
}
}
Stock クラスを使用できない理由を知っている人はいますか?
これが、あなたが求めたストック クラスです。public class Stock:Investment { //プライベート double stockPrice 属性;
//constructors
public Stock()
{
}
public Stock(string anInvestmentID, string anInvestmentName, string anInvestmentSymbol,
int anInvestmentShare, CustomerAccount aCustomer, double aStockPrice)
: base(anInvestmentID, anInvestmentName, anInvestmentSymbol, anInvestmentShare)
{
SetStockPrice(aStockPrice);
}
//
public Stock(string anInvestmentID, string anInvestmentName, string anInvestmentSymbol,
int anInvestmentShare, CustomerAccount aCustomer, double aStockPrice)
{
SetInvestmentID(anInvestmentID);
SetInvestmentName(anInvestmentName);
SetInvestmentSymbol(anInvestmentSymbol);
SetInvestmentShare(anInvestmentShare);
SetStockPrice(aStockPrice);
}
//set accessors
public void SetStockPrice(double aStockPrice)
{
stockPrice = aStockPrice;
}
//get accessors
public double GetStockPrice()
{
return stockPrice;
}
