这篇文章主要介绍了C# 将Access中以时间段条件查询的数据添加到ListView中,需要的朋友可以参考下

一、让ListView控件显示表头的方法

在窗体中添加ListView 空间，其属性中设置：View属性设置为：Detail，Columns集合中添加表头中的文字。

二、利用代码给ListView添加Item。

首先，ListView的Item属性包括Items和SubItems。必须先实例化一个ListIteView对象。具体如下：

ListViewItem  listViewItem=new ListViewItem();
listViewItem.SubItems[0].Text=""11111;//第一行第一例的值
listViewItem.SubItems.Add("222");///
listViewItem.SubItems.Add("222");///以此类推
ListView1.Items.Add(listViewItem);

三、Access中时间段查询的SQL语句书写规范（采用dateTimePick控件）

注意：# 是必须要加的

string sql=select * from tableName where timeField between #"+dateTimePick1.value.ToString()+"# and #"+dateTimePick2.vlaue.ToString()+"#";

Copy after login

四、连接数据库，按条件查询数据并显示在ListView中

string path = System.Environment.CurrentDirectory + "\\database.mdb";
      OleDbConnection con = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path);//station2.mdb
      con.Open();
      string sql = "select * from SendRecord where SENDTIME between #" + dateTimePicker1.Value.ToString() + "# and #" + dateTimePicker2.Value.ToString() + "#";
      // string sql = "select * from SendRecord";
      OleDbDataAdapter da = new OleDbDataAdapter(sql, con);
      DataSet dt = new DataSet();
      da.Fill(dt);
      DataTable dtb = dt.Tables[0];
      foreach (DataRow row in dtb.Rows)
      {
        ListViewItem listviewItem = new ListViewItem();
        listviewItem.SubItems.Clear();
        listviewItem.SubItems[0].Text = string.Format("{0:yyyy-MM-dd HH:mm}", row["SENDTIME"]);
        listviewItem.SubItems.Add((string)row["SENDER"]);
        listviewItem.SubItems.Add((string)row["CONTENT"]);
        listviewItem.SubItems.Add(string.Format("{0}", row["AUDITOR"]));
        listviewItem.SubItems.Add(string.Format("{0:yyyy-MM-dd HH:mm}", row["AUDITTIME"]));
        listviewItem.SubItems.Add(string.Format("{0}", row["AUDITSTATUS"]));
        listView1.Items.Add(listviewItem);
      }
      con.Close();
}

Copy after login
