如何设置物理路径上传Asp.Net文件？ [英] How to set physical path to upload a file in Asp.Net?

问题描述

我要在物理路径的文件上传如 E：\\项目\\文件夹

I want to upload a file in a physical path such as E:\Project\Folders.

我在网上搜索了以下code。

I got the below code by searching in the net.

//check to make sure a file is selected
if (FileUpload1.HasFile)
{
    //create the path to save the file to
    string fileName = Path.Combine(Server.MapPath("~/Files"), FileUpload1.FileName);
    //save the file to our local path
    FileUpload1.SaveAs(fileName);
}

但在这，我想正如我上面提到给我的物理路径。如何做到这一点？

But in that, I want to give my physical path as I mentioned above. How to do this?

推荐答案

使用Server.Mappath（〜/文件）返回基于相对于文件夹的绝对路径你的申请。领先〜/ 告诉ASP.Net来看看你的应用程序的根目录。

Server.MapPath("~/Files") returns an absolute path based on a folder relative to your application. The leading ~/ tells ASP.Net to look at the root of your application.

要使用一个文件夹中的应用程序之外：

To use a folder outside of the application:

//check to make sure a file is selected
if (FileUpload1.HasFile)
{
    //create the path to save the file to
    string fileName = Path.Combine(@"E:\Project\Folders", FileUpload1.FileName);
    //save the file to our local path
    FileUpload1.SaveAs(fileName);
}

当然，你不会硬code在生产应用程序的路径，但这应该使用您所描述的绝对路径保存文件。

Of course, you wouldn't hardcode the path in a production application but this should save the file using the absolute path you described.

至于定位文件，一旦你已经救了它（每评论）

With regards to locating the file once you have saved it (per comments):

if (FileUpload1.HasFile)
{
    string fileName = Path.Combine(@"E:\Project\Folders", FileUpload1.FileName);
    FileUpload1.SaveAs(fileName);

    FileInfo fileToDownload = new FileInfo( filename ); 

    if (fileToDownload.Exists){ 
        Process.Start(fileToDownload.FullName);
    }
    else { 
        MessageBox("File Not Saved!"); 
        return; 
    }
}
