C# UWP 查看两个数据库行

Question

string myConnectionString;

myConnectionString = "server=localhost;uid=root;pwd=root;database=medicloud;SslMode=None;charset=utf8";

MySqlConnection connection = new MySqlConnection(myConnectionString);

MySqlCommand cmd = new MySqlCommand();

cmd.CommandType = CommandType.Text;

string sqlStr = "Select arm from assign where userId=@name";

cmd.Parameters.AddWithValue("@name", txtValue.Text);

cmd.CommandText = sqlStr;

cmd.Connection = connection;

EncodingProvider ppp;

ppp = CodePagesEncodingProvider.Instance;

Encoding.RegisterProvider(ppp);

connection.Open();

MySqlDataReader reader = cmd.ExecuteReader();

reader.Read();

string databaseLine = (reader["arm"].ToString());

connection.Close();

#endregion

txtExercise.Text = databaseLine + " (Uncomplete)\n" + databaseLine;

我正在尝试查看数据库中的两行数据。但是，我不知道如何查看它。有人能帮我吗？我尝试输入“databaseLine”两次，但都查看同一行

如您所见，Rachel有两种类型的锻炼。我想在txtExercise.Text上查看这两个练习。但是我只能查看第一个，我无法查看第二个。
