C＃如何将可执行文件复制到目录中 [英] C# how to copy executable to a directory

问题描述

您好，我正在尝试将我的程序复制到％appdata％\ master文件夹中。这是我的代码。

 //这是用于创建目录
 string a = 
 Environment.GetFolderPath（Environment.SpecialFolder.ApplicationData） .ToString（）+\\Master \\; 
 DirectoryInfo di = Directory.CreateDirectory（a）; 
 //这是用于获取exe路径
 string src = System.Diagnostics.Process.GetCurrentProcess（）。MainModule.FileName; 
 //这是我要复制exe 
字符串的地方dest = Environment.GetFolderPath（Environment.SpecialFolder.ApplicationData）.ToString（）+\\\\\\\\\\\\\ 
 File.Copy（src，dest）; 

我收到此错误：



< blockquote class =quote>

Quote：

System.IO.DirectoryNotFoundException未处理

消息：未处理的异常在mscorlib.dll中输入'System.IO.DirectoryNotFoundException'

附加信息：找不到路径'C：\Users\ShomilaC\AppData \Roaming\Master的一部分\'。

提前致谢

解决方案

< blockquote>将文件复制到另一个目录时，还必须指定文件名;现在你正在复制到％AppData％\ Master ，但你必须复制到％AppData％\ Master \ FileNameHere.exe 。使用此 File.Copy 调用正确复制可执行文件：

 File.Copy（src，Path.Combine） （dest，Path.GetFileName（src）））; 

Hello, I am trying to get my program copied on run to %appdata%\master folder. This is my code.

// this is for making a directory
string a =
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData).ToString() + "\\Master\\";
            DirectoryInfo di = Directory.CreateDirectory(a);
// this is for getting exe path
            string src = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName;
// this is where I want to copy the exe
            string dest = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData).ToString() + "\\Master\\";
            File.Copy(src, dest);

I get this error:

Quote:

System.IO.DirectoryNotFoundException was unhandled
Message: An unhandled exception of type 'System.IO.DirectoryNotFoundException' occurred in mscorlib.dll
Additional information: Could not find a part of the path 'C:\Users\ShomilaC\AppData\Roaming\Master\'.

Thanks in advance

解决方案

When you copy a file into another directory, you also have to specify a file name; right now you are copying to %AppData%\Master, but you have to copy to %AppData%\Master\FileNameHere.exe. Use this File.Copy call to copy the executable correctly:

File.Copy(src, Path.Combine(dest, Path.GetFileName(src)));
