Data Access Layer (DAL Example) in ASP.NET (C#)

DAL Example


DAL resides in appcode folder.It is a simple C# class.

Create a new folder name it appcode & now add a new C# class in it & write code for database connectivity.

//Import Required Namespace Here
public class       CALLConnection
{
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ConnectionString);
    public WisemiserSMS()
    {

    }
    #region properties

    string _phoneNumber;
    public string PhoneNumber { get { return _phoneNumber; } set { _phoneNumber = value; } }
    int _msgId;
    public int MessageId { get { return _msgId; } set { _msgId = value; } }
    int _userId;
    public int UserId { get { return _userId; } set { _userId = value; } }
    string _messageText;
    public string MessageText { get { return _messageText; } set { _messageText = value; } }
    DateTime _sentTime;
    public DateTime SentTime { get { return _sentTime; } set { _sentTime = value; } }
    string _userName;
    public string UserName { get { return _userName; } set { _userName = value; } }
    string _password;

 
    #endregion

    public void sentSMSFlag()
    {
    openConnection();
        DataSet ds = new DataSet();
        SqlCommand cmd = new SqlCommand("sp_smsSentFlag", con);
 
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@id", this.id);
        //cmd.Parameters.AddWithValue("@raiseflag", this.addedtime);

        cmd.ExecuteNonQuery();
        con.Close();
        cmd.Dispose();
    }

}


Now we can call it in our code like this  CALLConnection.sentSMSFlag()
