我有一个包含多个交易对象的列表。我想在加载窗体时,在 Datagridview 控件中显示这些交易对象,基本上 Datagridview 应该表示某种交易记录以显示列表中每个交易对象的数据。
我必须承认,在使用 Datagridviews 时我缺乏经验,我在理解我需要做什么方面遇到了一些困难。
我的问题是,我该如何让列表中每个对象的详细信息显示在 Datagridview 中?
以下是我的代码。
首先是交易类:
public class Transaction
{
// Class properties
private decimal amount;
private string type;
private decimal balance;
private string date;
private string transNum;
private string description;
// Constructor to create transaction object with values set.
public Transaction(decimal amount, string type, decimal currBal, string date, string num, string descrip)
{
this.amount = amount;
this.type = type;
this.balance = currBal;
this.date = date;
this.transNum = num;
this.description = descrip;
}
// Get and Set accessors to allow manipulation of values.
public decimal Amount
{
get
{
return amount;
}
set
{
amount = value;
}
}
public string Type
{
get
{
return type;
}
set
{
type = value;
}
}
public decimal Balance
{
get
{
return balance;
}
set
{
balance = value;
}
}
public string Date
{
get
{
return date;
}
set
{
date = value;
}
}
public string TransNum
{
get
{
return transNum;
}
set
{
transNum = value;
}
}
public string Description
{
get
{
return description;
}
set
{
description = value;
}
}
public decimal addCredit(decimal balance, decimal credit)
{
decimal newBalance;
newBalance = balance + credit;
return newBalance;
}
public decimal subtractDebit(decimal balance, decimal debit)
{
decimal newBalance;
newBalance = balance - debit;
return newBalance;
}
}
}
现在是“注册”表单的代码:
public partial class Register : Form
{
List<Transaction> tranList = new List<Transaction>();
public Register(List<Transaction> List)
{
InitializeComponent();
this.tranList = List;
}
private void Register_Load(object sender, System.EventArgs e)
{
//regView represents the Datagridview that I'm trying to work with
regView.AutoSize = true;
regView.DataSource = tranList;
regView.Rows.Add(tranList[0]);
}
}
这里是我得到的输出结果。
