2.我需要在一个Label控件里面显示出数据表里面的内容.怎么做呢?谢谢!
ListView也可以,说来听听.谢谢!

Answer 1

//ListView

DataTable dt = new DataTable();
dt = //从数据库得到的DataTable

string[] subItem = new string[dt.Rows.Count];

foreach (DataRow dr in dt.Rows)
{
subItem[0] = dr["字段1"].ToString();
subItem[1] = dr["字段2"].ToString();
subItem[2] = dr["字段3"].ToString();
...............
ListViewItem lvi = new ListViewItem(subItem);

this.listView1.Items.Add(lvi);
}

Answer 2

Label只能显示单个值，如果要显示表之类的二维数值，要用ListView，DataGridView等控件

问题补充：ListView也可以,说来听听.谢谢!

Answer 3

DataTable dt = new DataTable();//你的数据DataTable
label1.Text = "";
for (int ColumnIndex = 0; ColumnIndex < dt.Columns.Count; ColumnIndex++)
label1.Text += dt.Columns[ColumnIndex].ColumnName + " ";
for (int RowIndex = 0; RowIndex < dt.Rows.Count; RowIndex++)
{
for (int ColumnIndex = 0; ColumnIndex < dt.Columns.Count; ColumnIndex++)
label1.Text += dt.Rows[RowIndex][ColumnIndex].ToString() + " ";
label1.Text += @"
";
}
