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：

hello,

I want to get this path using file uploader i tried many thing but it giving me path like D:\\ video application\\wildlife but i want the path like: D:\\ wildlife with out my application folder name.
actually i want to pass path to this command:

_mhandler.CustomCommand = "-i D:\\WildLife.wmv -vf fade=in:1:400 C:\\ConvertedV.wmv";

谢谢和问候。

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; 
    }
}
