想要求助大神给我讲讲这段程序的意思
public class getSqlConnection
{
#region 代码中用到的变量
string G_Str_ConnectionString = @"Data Source=(local);Initial Catalog=db_CSManage;Integrated Security=True";//连接数据库
SqlConnection G_Con; //声明链接对象
#endregion
连接数据库以后,在下面这段代码中是如何实现引用的,求解释
public static int intReturn = 0;
tb_Company Company = new tb_Company();
tb_CompanyMenthod CompanyMenthod = new tb_CompanyMenthod();
tb_JhGoodsInfoMenthod jhgood = new tb_JhGoodsInfoMenthod();
public static int intFalg =0;
private void ControlStatus()
