C#探秘系列（九）WPF连接Mysql数据库

两个函数即可搞定：

private void GetData()
        {

            MySqlConnection connection = new MySqlConnection(myConnectionString);
            connection.Open();

            if (connection.State == System.Data.ConnectionState.Open)
            {
                connection.Close();
                LoadData();
            }

        }

        private void LoadData()
        {
            MySqlConnection connection = new MySqlConnection(myConnectionString);
            connection.Open();
            try
            {
                MySqlCommand cmd = connection.CreateCommand();
                cmd.CommandText = "select * from notes";
                MySqlDataAdapter adap = new MySqlDataAdapter(cmd);

                DataSet ds = new DataSet();
                adap.Fill(ds);
                //this.clothesListView.DataContext = ds.Tables[0].DefaultView;
                foreach(DataRow r in ds.Tables[0].Rows)
                {
                    string t = r["title"].ToString();
                    string d = r["date"].ToString();
                    string i = r["image"].ToString();
                    //NotesItem是自定义的控件，noteList是listBox
                    NotesItem noteTemp = new NotesItem(this, t, d, i);
                    notesList.Items.Add(noteTemp);
                }

            }
            catch (Exception)
            {
                throw;
            }
            finally
            {
                if (connection.State == System.Data.ConnectionState.Open)
                {
                    connection.Close();

                }
            }
        }

其中myConnectionString是登录的口令：

private String myConnectionString = "Server=localhost;Database=mydatabse;Uid=root;Pwd=password;";
