我们可以在Web应用程序中使用system.windows.forms的openfiledialog吗？ [英] Can we use openfiledialog of system.windows.forms in web application?

问题描述

我们可以在我的Web应用程序中使用System.Windows.Forms中提供的OpenFileDialog来浏览并获取所选访问数据库文件的完整路径，以便我可以导入该文件的数据。我实际上在本地实现了这个，但不确定它是否可以在现场工作。请建议。



我尝试了什么：



我实际实施了本地成功使用：

public string getSelectedfilePath（）

{

string str = string.Empty;

System.Windows.Forms.OpenFileDialog openFileDialog = new System.Windows.Forms.OpenFileDialog（）;

openFileDialog.Title =选择数据库文件;

openFileDialog.InitialDirectory = C：\\;

openFileDialog.Filter =访问数据库文件（* .mdb，* .accdb）| * .mdb; * .accdb |所有文件（*。*） | *。*;

openFileDialog.RestoreDirectory = true;

if（openFileDialog.ShowDialog（）== System.Windows.Forms.DialogResult.OK）

{

str = Convert.ToString（openFileDialog.FileName）;

}

return str;

}



但不确定它是否可以在现场使用。请建议。

推荐答案

你不应该在Asp.Net中使用 OpenFileDialog ，而应该去 Asp：FileUpload 控制



file-upload-control / [ ^ ]

FileUpload Control [ ^ ]

You should not use OpenFileDialog in Asp.Net, instead you should go for Asp:FileUpload Control

file-upload-control/[^]
FileUpload Control[^]
