ASPXページのリストを表示

Question

このC＃関数はリストを返します。関数は.dllファイルにあります。 ASPXページにリストを戻す方法。私はASP.Netを初めて使っていて、それをグリッドにバインドしようとしましたが、動作しません。

public static List<string>[] Select() 
{ 

    server = "localhost"; 
    database = "cdl"; 
    uid = "root"; 
    password = "password"; 
    string connectionString; 
    connectionString = "SERVER=" + server + ";" + "DATABASE=" + database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";"; 

    connection = new MySqlConnection(connectionString); 

    connection.Open(); 

    string query = "SELECT * FROM caleiddevice"; 

    //Create a list to store the result 
    List<string>[] list = new List<string>[3]; 
    list[0] = new List<string>(); 
    list[1] = new List<string>(); 
    list[2] = new List<string>(); 

    //Open connection 
    // if (this.OpenConnection() == true) 
    // { 
    //Create Command 
    MySqlCommand cmd = new MySqlCommand(query, connection); 
    //Create a data reader and Execute the command 
    MySqlDataReader dataReader = cmd.ExecuteReader(); 
    // MySqlDataAdapter myDataAdapter = new MySqlDataAdapter(query, connection); 
    //Read the data and store them in the list 
    while (dataReader.Read()) 
    { 
    list[0].Add(dataReader["device_id"] + ""); 
    list[1].Add(dataReader["status"] + ""); 
    list[2].Add(dataReader["timestamp"] + ""); 
    } 

    //close Data Reader 
    dataReader.Close(); 

    //close Connection 
    // this.CloseConnection(); 

    //return list to be displayed 
    return list; 
    //} 
    //else 
    //{ 
    // return list; 
    // } 
}

If (!IsPostBack)
