将数据表传递给另一个类-ASP.Net

Question

I would like to pass a datatable to the DataAccessLayer from aspx.cs page. DAL is another project and CountryDal is a class file in it. Unable to do it using the session object. What is the proper way to acheive this.

ASPX.CS

private countryDAL objDAL = new CountryDAL();

protected void btnSave_Click(object sender, EventArgs e)
{
  //code...
  Session["tbl"] = dt;    //dt is a datatable with some data
  objDAL.SaveTable();
}

DAL

public void SaveTable()
{
  DataTable dtSave = (DataTable)Session["tbl"];

  //code.....
}

Answer 1

Inject it into the method:

public void SaveTable(DataTable dtSave)

so then, when you call it, just do this:

objDAL.SaveTable(dt);

and you can get rid of this line:

Session["tbl"] = dt;
