如何在Asp.Net中设置上传文件的物理路径？

Question

我想在物理路径中上传文件,例如E:\Project\Folders.

我在网上搜索下面的代码.

//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);
}

但在这方面,我想像上面提到的那样给出我的物理路径.这该怎么做？

Answer 1

Server.MapPath("~/Files")返回基于相对于应用程序的文件夹的绝对路径.领先者~/告诉ASP.Net查看应用程序的根目录.

要使用应用程序之外的文件夹:

//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,您不会在生产应用程序中硬编码路径,但这应该使用您描述的绝对路径保存文件.

关于在保存文件后定位文件(每条评论):

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; 
    }
}
