C# 使用存储过程和c更新Asp.net表单#

我是visual studio的新手，尝试使用存储过程和c更新我的web表单。我的代码中有一些问题

C#代码

存储过程

ALTER PROCEDURE update_outlines 
    -- Add the parameters for the stored procedure here
        (
    @title varchar(100),
    @code varchar(100),
    @instructor varchar(100),
    @credit varchar(100),
    @topic1 varchar(200),
    @topic2 varchar(200),
    @topic3 varchar(200),
    @topic4 varchar(200),
    @topic5 varchar(200)

    )

AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    UPDATE outline
    SET

    [course_title]= @title,
        [instructor]=@instructor,
        [credit] =@credit,
        [topic1]=@topic1,
        [topic2]=@topic2,
        [topic3]=@topic3,
        [topic4]=@topic4,
        [topic5]=@topic5
        WHERE
        [course_code]= @code

END
GO

错误是什么？？？？请发布错误详细信息，以便我们能够轻松地告诉解决方案您遇到异常？假设输入错误，

initial K Catalog

在发布问题时应该

initial Catalog

为什么要在代码中添加两次CommandText。在添加值之前，我会先检查连接状态是否打开：if（conn.state==ConnectionState.Closed）conn.open（）；

ALTER PROCEDURE update_outlines 
    -- Add the parameters for the stored procedure here
        (
    @title varchar(100),
    @code varchar(100),
    @instructor varchar(100),
    @credit varchar(100),
    @topic1 varchar(200),
    @topic2 varchar(200),
    @topic3 varchar(200),
    @topic4 varchar(200),
    @topic5 varchar(200)

    )

AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for procedure here
    UPDATE outline
    SET

    [course_title]= @title,
        [instructor]=@instructor,
        [credit] =@credit,
        [topic1]=@topic1,
        [topic2]=@topic2,
        [topic3]=@topic3,
        [topic4]=@topic4,
        [topic5]=@topic5
        WHERE
        [course_code]= @code

END
GO
