Solution 1

You didn't specify what the actual problem is but have a look at the example in the documentation: http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqldataadapter.aspx[^].

It shows how to use the adapter to fill a datatable.

Some subtle differences between the reader and adapter mentioned at http://www.bestdotnet.com/2007/11/dataadapter-vs-datareader.html[^],

}
public SqlDataReader getData()
{
SqlDataReader dr = null;
SqlCommand comm = new SqlCommand();
try
{
comm.CommandText = "select * from emp";
comm.CommandType = CommandType.Text;
comm.Connection = new SqlConnection("Data Source=DELL-PC;Initial Catalog=employeee;User ID=sa;Password=shristi");
comm.Connection.Open();
if (comm.Connection.State == ConnectionState.Open)
