How to set physical path to upload a file in Asp.Net?
提问by thevan
I want to upload a file in a physical path such as E:\Project\Folders.
我想在物理路径中上传文件，例如E:\Project\Folders.
I got the below code by searching in the net.
我通过在网上搜索得到了以下代码。
//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);
}
But in that, I want to give my physical path as I mentioned above. How to do this?
但在那方面，我想给出我上面提到的物理路径。这该怎么做？

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.
Server.MapPath("~/Files")返回基于相对于您的应用程序的文件夹的绝对路径。前导~/告诉 ASP.Net 查看应用程序的根目录。
To use a folder outside of the application:
要使用应用程序外部的文件夹：
//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);
}
Of course, you wouldn't hardcode the path in a production application but this should save the file using the absolute path you described.
当然，您不会在生产应用程序中对路径进行硬编码，但这应该使用您描述的绝对路径保存文件。
With regards to locating the file once you have saved it (per comments):
关于在保存文件后定位文件（根据评论）：
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;
}
}

// 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);
}
