使用方法简单说明：

1、代码对比
 
1)传统Web网站数据库编程代码
 
GridView1.DataSource = ds.Tables[TableName1].DefaultView;
GridView1.DataBind();
 
2)使用DBOperator.Data数据库组件
        GridView1.DataSource = ds;
        GridView1.DataBind();
 
2、数据库配置

WebConfig里使用哪个数据库，就打开哪个。

 
       
 
3、数据源调用

例如：1) DataSet调用方法：
    protected void Page_Load(object sender, EventArgs e)
    {
        DataSet ds = osdData.DataSet("SELECT * FROM XiaoYin_User", 0, 0, "dsTable");//使用组
       件的scData类，实现DataSet功能
        //数据源
        GridView1.DataSource = ds;
        //为GridView绑定数据
        GridView1.DataBind();
    }
      2) Reader调用方法：
      protected void Page_Load(object sender, EventArgs e)
      {
        //使用scReader类，实现DataReader功能
        osdReader dr = new osdReader("SELECT * FROM XiaoYin_User");
        //循环启动阅读器
        while (dr.Read())
        {
            //输出指定列
            Response.Write(dr["u_name"] + "
");
        }
        dr.Close();//关闭阅读器
      }

实现功能：
     
osdDataSet类
     读取(DataSet方式)，插入，更新，删除，统计
     1,读取
       DataSet ds=osdData.DataSet("SELECT * FROM 表 WHERE 条件",开始行,多少行,"虚拟表名");
     2,插入
       osdData.ExecuteNonQuery("INSERT INTO 表 (列1，列2) VALUES (变量1,变量2)");
     3,更新
       osdData.ExecuteNonQuery("UPDATE 表 SET 列1=变量A,列2=变量B WHERE 条件");
     4,删除
       osdData.ExecuteNonQuery("DELETE 表 WHERE 条件");
     5,统计
       osdData.ExecuteScalar("SELECT * FROM 表 WHERE 条件",统计类型)
统计类型分两种：

       int 整型：1
       double 带小数点：2
//---------- osdReader类 --------------------
实现功能：读取(DataReader阅读器方式)
调用方法：
osdReader dr=new osdReader("SELECT * FROM 表 WHERE 条件");
//--------------------------------------------
if(dr.Read())
{
   //如果特定条件的值存在，立即终止下一行的读取
}
//--------------------------------------------
while(dr.Read)
{
   //循环读取符合条件的值
}
//--------------------------------------------
调用读取出来的值：
dr["列名"].ToString();
使用完后关闭：
dr.Close();
