[英]C# storing data from input to arraylist inside Class
I have got a class called Customers with an Arraylist inside to store information about the Customer Accounts; 我有一个叫做带有Arraylist的客户的班级来存储有关客户账户的信息; then inside Accounts class I have an Arraylist to hold the Transactions.
在Accounts类中,我有一个Arraylist来保存Transactions。
My question is, how would I go about saving to the Arraylist found within the Customer Class. 我的问题是,我将如何保存到客户类中找到的Arraylist。 It doesnt seem like I can access it.
它似乎无法访问它。
if (allInputOK)
{
//create Account
Account temp = new Account(tempAccSortCode, tempAccNumber, tempAccNickName, tempAccDate, tempAccCurBal, tempAccOverDraft, tempNumTrans);
//add to array
//Need to add here.
//finish up
MessageBox.Show("Success Account added ");
resetForm();
}
This is my method on a form to add to the Arraylist. 这是我在表单上添加到Arraylist的方法。 It first checks the input is OK, then creates a new Account called temp (Account is the Class name).
它首先检查输入是否正常,然后创建一个名为temp的新帐户(Account是类名)。 Then how do I go about saving this inside of the Arraylist inside the Class Account?
那么如何在课堂账户中将其保存在Arraylist中呢?
Thanks. 谢谢。
public class Account
{
}
public class Customer
{
public ArrayList Accounts
{
get;
private set;
}
public Customer()
{
Accounts = new ArrayList();
}
public void AddAccount(Account account)
{
// if account is valid add it to the local collection
Accounts.Add(account);
}
}
Then in your code: 然后在你的代码中:
if (allInputOK)
{
//create Account
Account temp = new Account(tempAccSortCode, tempAccNumber, tempAccNickName, tempAccDate, tempAccCurBal, tempAccOverDraft, tempNumTrans);
//add to array
_customer.AddAccount(temp);
//finish up
MessageBox.Show("Success Account added ");
resetForm();
}
Building on Swaff's answer earlier, just make your Accounts
ArrayList
private and expose the AddAccount functionality: 基于Swaff之前的回答,只需将您的
Accounts
ArrayList
设为私有并公开AddAccount功能:
public class Customer {
private ArrayList _accounts = new ArrayList();
...
public void AddAccount(Account theAccount){
//do some validation...if OK, then add to ArrayList...
_accounts.Add(theAccount);
}
//you'll also need facade methods to retrieve accounts
}
