今天写了个c#下listview的排序，若果显示的量小，用这个感觉很方便。mysql的数据库

private int g_nColumn = 0;

private int g_nSort = 0;

private string[] g_column = { "id", "username", "pwd", "t1", "t2", "t3", "t4", "t5", "t6" };

private void listView1_ColumnClick(object sender, ColumnClickEventArgs e)

{

try

{

listView1.Items.Clear();

MySqlClientFactory factory = MySqlClientFactory.Instance;

MySqlConnection conn = new MySqlConnection();

conn.ConnectionString = string.Format("server={0};user id={1}; password={2}; database={3}; port={4}; pooling=false",

"ServerAddress", "tb_user", "uername", "pwd", 3306);

conn.Open();

string strSql ="";

if (g_nSort == 0)

{

strSql = String.Format("select * from tb");

}

if (g_nSort == 1)

{

strSql = String.Format("select * from tb order by {0} DESC",g_column[e.Column]);

}

if (g_nSort == 2)

{

strSql = String.Format("select * from tb order by {0}", g_column[e.Column]);

}

MySqlDataAdapter mysqlDa = new MySqlDataAdapter(strSql, conn);

DataTable tb = new DataTable();

mysqlDa.Fill(tb);

conn.Close();

g_nSort += 1;

g_nSort = g_nSort % 3;

listView1.Items.Clear();

for (int i = 0; i < tb.Rows.Count; i++)

{

ListViewItem lt = new ListViewItem(tb.Rows[i][0].ToString());

lt.SubItems.Add(tb.Rows[i][1].ToString());

lt.SubItems.Add(tb.Rows[i][2].ToString());

lt.SubItems.Add(tb.Rows[i][3].ToString());

lt.SubItems.Add(tb.Rows[i][4].ToString());

lt.SubItems.Add(tb.Rows[i][5].ToString());

lt.SubItems.Add(tb.Rows[i][6].ToString());

lt.SubItems.Add(tb.Rows[i][7].ToString());

lt.SubItems.Add(tb.Rows[i][8].ToString());

listView1.Items.Add(lt);

}

}

catch (Exception ex)

{

//MessageBox.Show(ex.Message);

}

}
