using System;
using System.Data;
using System.Data.SqlClient;public class ztx

    void page_Load()
    {
        string strConnection = "";
        strConnection = "server=127.0.0.1;";
        strConnection += "database=ztx;uid=sa;password=wxj;";
        string strSql = "seelct i_id,i_caption from content";
        SqlConnection sqlConnection2 = new SqlConnection(strConnection);
        SqlCommand sqlCommand2 = new SqlCommand(strSql, sqlConnection2);        zhangtianxing.DataSource = sqlCommand2.ExecuteReader(CommandBehavior.CloseConnection);
        zhangtianxing.DataBind();
    }
}如果正确,那么该如何调用?
