저는 C#을 처음 사용합니다. Kudvenkat 자습서의 간단한 예제를 따라하면됩니다. http://csharp-video-tutorials.blogspot.com/2012/10/calling-stored-procedure-with-output.htmlWebForm1에 'Context'에 대한 정의가 없습니다.
오류가 계속 발생하면서 내가 뭘 잘못하고 있는지 이해할 수 없습니까?
내에서 .aspx 파일 : 내 aspx.cs에서
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="WebForm1.aspx.cs" Inherits="WebForm1"%>
