我遇到了一些错误，而且我的代码尚未完成。我正在使用另一个 Stackoverflow 问题来设置它，但它不适合我的需求。
我有三个文本文件，数据用逗号分隔，例如"Name，25,25.6"，所以字符串，int，十进制。我有所有三个文本文件，它们有三列，相同的数据类型，但名称/数字不同。
我有三个不同的列表框，我想将它们拆分为三个不同的列表框，但我无法让三个不同的拆分列表项进入三个不同的列表框。我将复制并粘贴我拥有的所有代码。我还使用组合框允许用户选择要加载到组合框中的文件，我相信我做对了。
我得到的错误在displayLists()中，它在lstItemName.DataSource = Inventory上说;行说Inventory在当前上下文中不存在。还有大量其他错误。
任何帮助将不胜感激，我会复制并粘贴我的代码。我有一个 Windows 窗体，并且使用的是 C# 中的 Visual Studio Express 2012
namespace TCSCapstone
{
public partial class frmInventory : Form
{
public frmInventory()
{
InitializeComponent();
}
string cstrItemName;
int cintNumberOfItems;
decimal cdecPrice;
decimal cdecTotalPrices;
string selectedList = "";
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
selectedList = this.cmbList.GetItemText(this.cmbList.SelectedItem);
if (selectedList == "Creative Construction")//if the selected combo
box item equals the exact string selected
{
selectedList = "creative"; //then the string equals creative,
which is creative.txt but I add the .txt in the btnLoadInfo method
} else if (selectedList == "Paradise Building")
{
selectedList = "paradise";//this is for paradise.txt
}
else if (selectedList == "Sitler Construction")
{
selectedList = "sitler";//this is for sitler.txt
}
else
{
MessageBox.Show("Please select one of the items.");
}
}
private void btnLoadInfo_Click(object sender, EventArgs e)
{
List<frmInventory> Inventory = new List<frmInventory>();
using (StreamReader invReader = new StreamReader(selectedList +
".txt"))
{
while (invReader.Peek() >= 0)
{
string str;
string[] strArray;
str = invReader.ReadLine();
strArray = str.Split(',');
frmInventory currentItem = new frmInventory();
currentItem.cstrItemName = strArray[0];
currentItem.cintNumberOfItems = int.Parse(strArray[1]);
currentItem.cdecPrice = decimal.Parse(strArray[2]);
Inventory.Add(currentItem);
}
}
displayLists();
}//end of btnLoadInfo
void displayLists()
{
int i;
lstItemName.Items.Clear();
lstNumberOfItems.Items.Clear();
lstPrice.Items.Clear();
lstTotalPrices.Items.Clear();
lstItemName.DataSource = Inventory;
lstItemName.ValueMember = "cstrItemName";
lstItemName.DisplayMember = "cintNumberOfItems";
}
}//end of frmInventory
}//end of namespace
我不知道这是否正是您所需要的，但请尝试以下操作：
public partial class Form2 : Form
{
List<Inventory> inventory;
public Form2()
{
InitializeComponent();
}
public void ReadFiles()
{
if (inventory == null)
inventory = new List<Inventory>();
using (TextReader r = new StreamReader("file.txt"))
{
string line = null;
while ((line = r.ReadLine()) != null)
{
string[] fields = line.Split(',');
Inventory obj = new Inventory();
obj.Name = fields[0];
obj.Qtd = Convert.ToInt32(fields[1]);
obj.Price = Convert.ToInt32(fields[2]);
inventory.Add(obj);
}
}
SetDataSourceList();
}
public void SetDataSourceList()
{
listBox1.DisplayMember = "Name";
listBox2.DisplayMember = "Qtd";
listBox3.DisplayMember = "Price";
listBox1.DataSource =
listBox2.DataSource =
listBox3.DataSource =
inventory;
}
}
public class Inventory
{
public string Name { get; set; }
public int Qtd { get; set; }
public decimal Price { get; set; }
}
