c# - c# 试图从另一个方法访问某些东西

Question

我是新手，所以希望你们能忍受我。我正在尝试在 btnDone 时将 filePathImage 的 URL 目录插入数据库。部分代码：

  protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
    {
        EnsureDirectoriesExist();


        String filepathImage = (@"Images/Story/" +txtTitle.Text + "/" + e.FileName);


        AjaxFileUpload1.SaveAs(Server.MapPath(filepathImage));


    }

 protected void btnDone_Click(object sender, EventArgs e)
    {

        act.ActivityName = dropListActivity.SelectedItem.Text;
        act.Title = txtTitle.Text;

        act.FileURL = filepathImage;

        daoStory.Insert(act);
        daoStory.Save();
    }

我在 act.FileURL = AjaxFileUpload1.filePathImage 中遇到了 filePathImage 的问题；任何建议或解决方案将不胜感激

在下面尝试，上传完成后，您可以将路径放入会话并在需要时采用该会话路径。

protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{

  // your Code 
  Session["filepathImage"] = filepathImage ; // put the path in session variable 

}

protected void btnDone_Click(object sender, EventArgs e)
{
    if(Session["filepathImage"]!=null)
    {
         string filepathImage = Session["filepathImage"] as string;
         // your code ...
    }
}
