问题描述
这是死机，给我这个错误的部分是，当我尝试将文件复制到一个特定的位置。
This is the part that crashes and gives me this error is when I try to copy a file to a certain location.
string startupDirectory = "C:\\Users\\Tyler\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup";
File.Copy(startupDirectory, "Startup.exe");
我已经在网上阅读，并试图管理员权限，并创造了一个app.manifest的文件：
I have read online and tried administrator rights and have created an "app.manifest" file:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
<requestedExecutionLevel level="highestAvailable" uiAccess="false" />
我证实，在设置中，应用程序清单设置为这个文件，但它仍然给我。同样的错误。
I confirmed that in the settings, the app manifest is set to this file, but it still gives me the same error.
我也尝试过这个活动，虽然我没想到它会工作，因为它是一个目录不是一个文件：
I have also tried this event though I didn't think it would work because it is a directory not a file:
File.SetAttributes(startupDirectory, FileAttributes.Normal);
这是WinForms和我在Windows 7中，还希望它世界的窗口8+。我该怎么做呢？
This is WinForms and I am on windows 7 but also want it to world for windows 8+. How do I do this?
在此先感谢！
推荐答案
尝试
public static void Copy(string sourceFileName, string destFileName);
首先过载源第2个过载的目标，我认为原因可能是这个
First overload is source 2nd overload is destination i think reason might be this
File.Copy("Startup.exe",startupDirectory);
尝试设置访问权限为完全控制为.NET用户从你正在阅读的地方/保存文件。
Try setting the access permissions to "Full control" for the .Net user from where you are reading/saving the files.
有关在IIS服务器的特定文件的访问拒绝错误，请按照以下步骤
For Access Denied Error in IIS server for particular file , please follow the below steps
1- Goto to C:\\Users\\Tyler\\AppData\\Roaming\\Microsoft\\Windows\\Start Menu\\Programs\\Startup
2- Right click on your file -> Properties -> Pop Up of User properties appears -> click on Security tab-> click on Edit -> select Users-> tick on Allow Full Control -> Click Ok
这必将解决了拒绝访问的问题。
This will surely solve the Access denied problem
这是UnauthorizedAccessException意味着三件事之一：
An UnauthorizedAccessException means one of 3 things:
- 调用方没有所要求的权限
- 路径是一个目录。
- 路径指定的只读文件。
