In this article, you'll see how to use SqlConnection and SqlCommand ADO.NET objects. First thing is, namespaces. There is no namespace called System.Data.SQL any more. IT has been changed with System.Data.SqlClient. See http://www.c-sharpcorner.com/Beta%202/adonet1.asp for more details.

If you had program in Beta 1, your code would look like this -
如果你用beta1编过程序，你的代码会看起来象下面的样子
<%@ Import Namespace="System.Data.SQL" %>
SQLDataReader myReader;
SQLConnection myConnection = new SQLConnection("server=localhost;uid=sa;pwd=sa;database=Shivani");
SQLCommand myCommand = new SQLCommand("Select * from ShivaniArea, myConnection);

try
{
myConnection.Open();
myCommand.Execute(out myReader);

while (myReader.Read())
{

// Retrieve the fields  
}
  



and now new version of Beta 2 looks like this -
现在新版本的Beta2中看起来这样
  
<%@ Import Namespace="System.Data.SqlClient"%>
SqlDataReader myReader;

SqlConnection myConnection = new SqlConnection("server=localhost;uid=sa;pwd=sa;database=Shivani");
SqlCommand myCommand = new SqlCommand("Select * from ShivaniArea", myConnection);
try
{
      myConnection.Open();
      myReader = myCommand.ExecuteReader;

while(myReader.Read())
{
    //Retrieve the fields
}
}  

During the testing of my mobile applications, I noticed more problems working with Beta 1 code. I was having problem working with the TagPrefix. Any way .. I'll be coming with more articles on this matter soon and keep updating you on Beta 2. In my next article, I will discuss how to deal with the problem of losing the DocumentNavigator Class in XML and take the real use of XMLDocument Class.
