如何在c＃中从BLL访问DataSet

Question

I'm sorry for the question, but I'm new with the BLL :(

I have my DAL with a dsUsers.xsd created.

Now I'm trying to develop the BLL for UserBLL,

I realized that in some examples on the web, they make reference to the table adapters like this:

using System.Data.SqlClient;
using dsUserTableAdapters;

But every time I trying to add the last part of the above code, I get nothing starting with that name,

Do I missing something here?

Answer 1

You need to add a reference to your DAL library to your BLL. Then, you can reference the dataset like so:

using MyDal.MyDataSetNamespace;

You can then create an object of your dataset type

MyDataSet ds = new MyDataSet();

EDIT: To add a reference of your DAL to your BLL, right click the BLL project and choose Add Reference . In the window that pops up, choose the Projects tab and select your DAL project.
