c＃試圖從另一種方法訪問的東西

Question

我對此很陌生，所以希望你們能忍受我。我試圖在btnDone上插入數據庫filePathImage的URL目錄。 部分代碼：

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(); 
    } 

i的act.FileURL = AjaxFileUpload1.filePathImage得到了與filePathImage一個問題;任何意見或解決方案將不勝感激

請嘗試下面，當上傳完成時，你可以把你的路徑進入會議，並在需要時採取會話路徑。

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 ... 
    } 
}
