在aspx网页和类之间传递值 [英] Pass Values Between aspx webpage and class

问题描述

我想知道如何从另一个CS文件中的某个aspx页面调用Label.例如:

I am wondering how to call a Label from a certain aspx page in another cs file. For example:

protected void Button1_Click(object sender, EventArgs e)
    {
        Test1.Insert1(this);
    }

我在Something.aspx.cs文件中有这段代码，可以从我创建的另一个CS文件中调用一个方法，如下所示:

This code i have in the Something.aspx.cs file to call a method from another cs file i created which looks like:

public static class Test1 
{
    public static void Insert1(System.Web.UI.Page Ins)

     {
        string conn = "Data Source=pc-...";
        System.Data.SqlClient.SqlConnection sqlConn = new System.Data.SqlClient.SqlConnection(conn);
        if (Page.IsValid)
        {
            try
            {
                sqlConn.Open();
                Ins.LabelAdd.Text = "Worked!";
                System.Data.SqlClient.SqlCommand myCommand = new System.Data.SqlClient.SqlCommand("INSERT INTO ... ", sqlConn);
                myCommand.ExecuteNonQuery();
            }
            catch (Exception ex)
            {
                Ins.LabelAdd.Text = "Error! " + ex;
            }
            finally
            {
                sqlConn.Close();
            }
        }
    }
}

但这不起作用.我之前可以通过会话完成此操作，但这无法正常工作.我无法调用在Something.aspx页中使用的LabelAdd.关于如何解决此问题的任何想法?谢谢.

But this doesn't work. I was able to do this before with a session but this won't work. I can't call the LabelAdd which I used in the Something.aspx page. Any ideas on how I can fix this? Thank you.

推荐答案

您需要传递控件引用，例如...

You need to pass your control Reference like...

public static void Insert1(Label lblId)

还请在您的课程中使用System.Web.UI.WebControls; 添加此

also please add this using System.Web.UI.WebControls; in your class
