如何在c sharp中获取本地文件位置 [英] how to get local file location in c sharp
问题描述
你好,
如何在asp.net中使用文件上传器获取文件的本地路径,就像我浏览文件 D:\\wildlife.flv
我想使用文件上传器获取此路径我尝试了很多东西,但它给了我路径,如 D:\\ video application \\wildlife 但是我希望路径如下: D:\\ wildlife 我的应用程序文件夹名称。
实际上我想将路径传递给此命令:

推荐答案
我认为这个解决方案可以帮助你......克服你的问题...
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。领先的〜/告诉ASP.Net查看你的应用程序的根目录。
使用应用程序之外的文件夹:
I think This Solution Will Help you...to overcome from your problem...
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.
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,你不会在生产应用程序中硬编码路径,但这应该使用你描述的绝对路径保存文件。 />
关于在保存文件后查找文件(每条评论):
Of course, you wouldn''t hardcode the path in a production application but this should save the file using the absolute path you described.
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;
}
}
