namespace Database_Updation

    class Program
    {
        static void Main(string[] args)
        {
            SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["MyDbConn1"].ToString());

            SqlCommand cmd = new SqlCommand("SELECT [GUID] FROM [Source].[dbo].[Source_User]", cn);
            cn.Open();
            SqlDataReader rdr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
            rdr.Read();
            Response.Write(rdr[0].ToString()); //read a value

        }
    }
}

我收到错误消息当前上下文中不存在名称“Response”

Answer 1

尝试使用

Console.Write(rdr[0].ToString()); //Write a value 

代替

Response.Write(rdr[0].ToString()); //Write a value

希望对你有帮助
