连接数据库的步骤:
  1、建立SqlConnection对象;
  2、指定SqlConnection对象的ConnectionString 属性;
  3、打开数据库连接;
  4、指定SQL语句;
  5、建立SqlDataAdapter对象和DataSet对象(myDataAdapter = new SqlDataAdapter(strCmd,conn);
);
  6、添冲DataSet;
  7、给DataGrid指定数据源

SqlConnection conn = new SqlConnection();
   conn.ConnectionString = "data source = (local);initial catalog = test; user id = sa;password = sa";
   conn.Open();
   string strCmd;
   strCmd = "select * from test";
   SqlDataAdapter myDataAdapter;
   DataSet myDataSet = new DataSet();
   myDataAdapter = new SqlDataAdapter(strCmd,conn);
   myDataAdapter.Fill(myDataSet,"test");
   myTestDataGrid.DataSource = myDataSet.Tables["test"];

说明: 数据库安装在本地(local);数据库名称为test;用户名为sa;密码为sa;
数据库中的表为test;
