如何设置物理路径上传Asp.Net文件？(How to set physical path to u

我想上传一个文件，如物理路径E:\Project\Folders 。

我在网上搜索了下面的代码。

//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);
}

但在那，我想正如我上面提到给我的物理路径。 这该怎么做？

Answer 1:

Server.MapPath("~/Files")返回基于相对于你的应用程序文件夹的绝对路径。 领先的~/告诉ASP.Net来看看你的应用程序的根。

要使用文件夹的应用程序之外：

//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，你也不会硬编码在生产应用程序的路径，但是这应该使用您所描述的绝对路径保存文件。

至于定位文件，一旦你已经救了它（每评论）：

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; 
    }
}

Answer 2:

好，

您可以通过完成此VirtualPathUtility

Answer 3:

// Fileupload1 is ID of Upload file
if (Fileupload1.HasFile)
{
    // Take one variable 'save' for store Destination folder path with file name
    var save = Server.MapPath("~/Demo_Images/" + Fileupload1.FileName);
    Fileupload1.SaveAs(save);
}
