无法访问文件，因为它被另一个进程使用 [英] Cant Access File because it is being used by another process

问题描述

我有一个ASP.NET程序，我正在使用webClient类的DownloadFile方法从Web下载文件，并对其进行一些修改。然后我将其保存到具有唯一名称的另一个文件夹。当我收到此错误

进程无法访问文件D： \RDE\\\\\\\\\\\\\\\\\\\\\\,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, $ b

任何人都可以告诉我如何解决这个问题。

解决方案

一般来说，我认为你的代码应该是这样的。

  WebClient wc = new WebClient（）; 
 wc.DownloadFile（http://stackoverflow.com/Content/Img/stackoverflow-logo-250.png，Foo.png）; 
 FileStream fooStream; 
 using（fooStream = new FileStream（foo.png，FileMode.Open））
 {
 // do stuff 
} 
 File.Move（foo .png，foo2.png）; 
  

I have an ASP.NET program where i am downloading a file from web using DownloadFile method of webClient Class and the do some modifications on it. then i am Saving it to another folder with a unique name.When I am getting this error

The process cannot access the file 'D:\RD\dotnet\abc\abcimageupload\images\TempStorage\tempImage.jpg' because it is being used by another process

Can anyone tell me how to solve this.

解决方案

Generally, I think your code should looking something like this.

WebClient wc = new WebClient();
wc.DownloadFile("http://stackoverflow.com/Content/Img/stackoverflow-logo-250.png", "Foo.png");
FileStream fooStream;
using (fooStream = new FileStream("foo.png", FileMode.Open))
{
    // do stuff
}
File.Move("foo.png", "foo2.png");
