我是C＃的新手并且已经遇到了问题。我正在编写一个程序来显示一天或一天之间分开的事件。我没有很多处理访问数据库的经验，但我听说它们比SQL数据库更容易使用。我正在使用搜索查询来查找每天的事件，然后将他们的“描述”元素放入列表框中，以适应一周中的适当日期。当我运行该程序工作正常，但没有用事件填充列表框。
我确信我的代码在许多方面都是非常错误的，但正如我所说，我仍在学习C＃。我一直在互联网上寻找并尝试了几乎所有我能找到的“解决方案”，到目前为止还没有任何工作。任何帮助深表感谢。 Windows窗体的代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace USA_ETK
{
public partial class StartUp : Form
{
private DateTime tempToday = DateTime.Today;
private DateTime beginofweek;
private DateTime endofweek;
public StartUp()
{
InitializeComponent();
findWeek(tempToday);
startUp_begin();
}
private void newSessionsToolStripMenuItem_Click(object sender, EventArgs e)
{
New_Session newSessionWindow = new New_Session();
newSessionWindow.Visible=true;
}
private void exitToolStripMenuItem_Click(object sender, EventArgs e)
{
Close();
}
private void findWeek(DateTime tt)
{
DayOfWeek day = tt.DayOfWeek;
int days = day - DayOfWeek.Sunday;
beginofweek = tt.AddDays(-days);
endofweek = beginofweek.AddDays(6);
label8.Text = beginofweek.ToString("MM/dd/yyyy") + " - " + endofweek.ToString("MM/dd/yyyy");
}
private void button2_Click(object sender, EventArgs e)
{
tempToday.AddDays(7);
findWeek(tempToday);
}
private void button1_Click(object sender, EventArgs e)
{
tempToday.AddDays(-7);
findWeek(tempToday);
}
private void startUp_begin()
{
DateTime tempdate = new DateTime(beginofweek.Year, beginofweek.Month, beginofweek.Day, 00, 00, 00);
listBox1.DataSource = session_LogTableAdapter.GetDataBySearch(tempdate.Date);
tempdate.AddDays(1);
//listBox2.DataSource = session_LogTableAdapter.GetDataBySearch(tempdate.Date);
tempdate.AddDays(1);
listBox3.DataSource = session_LogTableAdapter.GetDataBySearch(tempdate.Date);
tempdate.AddDays(1);
listBox4.DataSource = session_LogTableAdapter.GetDataBySearch(tempdate.Date);
tempdate.AddDays(1);
listBox5.DataSource = session_LogTableAdapter.GetDataBySearch(tempdate.Date);
tempdate.AddDays(1);
listBox6.DataSource = session_LogTableAdapter.GetDataBySearch(tempdate.Date);
tempdate.AddDays(1);
listBox7.DataSource = session_LogTableAdapter.GetDataBySearch(tempdate.Date);
}
}
}

答案 0 :(得分：1)
设置数据源后尝试调用listBox1.DataBind()。重复其余部分。
答案 1 :(得分：0)
我不知道您的数据集被调用了什么，但我们假设您使用SQL查询的结果填充了一个名为DataSet1的DataSet。您的列表框名为ListBox1。你需要做这样的事情：
ListBox1.ItemsSource = DataSet1.Tables["tablename"];
OR
ListBox1.ItemsSource = DataSet1;
不确定哪一个有效，但我认为第二个很好。
希望这有帮助。
