Creating SQL Connections

using System;
using System.Data.SqlClient;
class MainClass 
{
  static void Main(string[] args)
  {
    SqlConnection MyConnection = new SqlConnection("Data Source=(local); Initial  Catalog = MyDatabase; User ID=sa;Password=");
    MyConnection.Open();
  }
}

Using DataTable Mappings

using System;
using System.Data;
using System.Data.rumon;
using System.Data.SqlClient;
class MainClass
{
  static void Main(string[] args)
  {
    SqlConnection SConn = new SqlConnection("Data Source=(local); Initial Catalog = CaseManager; Integrated Security=true");
    SqlDataAdapter da = new SqlDataAdapter("SELECT ID, FirstName, LastName FROM Employee", SConn);
    DataSet ds = new DataSet();
    DataTableMapping custMap = da.TableMappings.Add("Employee", "MyDatabase");
    custMap.ColumnMappings.Add("ID", "Number");
    custMap.ColumnMappings.Add("FirstName", "first name");
    custMap.ColumnMappings.Add("LastName", "last name");
    da.Fill(ds);
  }
}
