如果对您有帮助  请关注我：林新

 

using System.Data.SqlClient;

 

string conn = @"server=USER-20170520ES\SQLEXPRESS;database=Music;uid=sa;pwd=sa";

 

 

创建SQL语句，支持模糊搜索，如果不输入，就等于全选择

string sql = string.Format("select * from king_MuSic ");

SqlConnection con = null;

try

{

con = new SqlConnection(conn);

//命令对象

SqlCommand comm = new SqlCommand(sql,con);

con.Open();

 

SqlDataReader reader = comm.ExecuteReader();

if (reader.HasRows)

{

while (reader.Read())

{

ListViewItem item = new ListViewItem();

item.Text = reader["singername"].ToString();

item.SubItems.Add(reader["singer"].ToString());

item.SubItems.Add(reader["Album"].ToString());

this.listView1.Items.Add(item);

}

reader.Close();

 

}

 

}

catch (Exception ex)

{

MessageBox.Show("出现异常"+ex.Message);

}

 

 

 

 

 

 

 

放在加载事件里 这是dataGriderView

private void LoadData()

{

string sql = "select * from Sales_Returns1 order by datepurchase desc";

dataGridView1.DataSource = db.Select(sql);

}
