C# 中的网络复制命令 - 未找到文件？
我正在尝试将文件复制到映射驱动器上的网络文件夹。我在命令行中测试了 COPY 是否有效，因此我想尝试在 C# 中自动化该过程。
ProcessStartInfo PInfo;
Process P;
PInfo = new ProcessStartInfo("COPY \"" + "c:\\test\\test.txt" + "\" \"" + "w:\\test\\what.txt" + "\"", @"/Z");
PInfo.CreateNoWindow = false; //nowindow
PInfo.UseShellExecute = true; //use shell
P = Process.Start(PInfo);
P.WaitForExit(5000); //give it some time to finish
P.Close();
引发异常：System.ComponentModel.Win32Exception (0x80004005): 系统找不到指定的文件
我缺少什么？我还需要在命令参数中添加其他内容吗？
我尝试过 File.Copy 但它似乎不起作用 (File.Exists(") 显示 false。
I'm trying to copy a file over to a networked folder on a mapped drive. I tested out COPY in my command line which worked, so I thought I'd try automating the process within C#.
ProcessStartInfo PInfo;
Process P;
PInfo = new ProcessStartInfo("COPY \"" + "c:\\test\\test.txt" + "\" \"" + "w:\\test\\what.txt" + "\"", @"/Z");
PInfo.CreateNoWindow = false; //nowindow
PInfo.UseShellExecute = true; //use shell
P = Process.Start(PInfo);
P.WaitForExit(5000); //give it some time to finish
P.Close();
Raises an exception : System.ComponentModel.Win32Exception (0x80004005): The system cannot find the file specified
What am I missing? Would I have to add anything else to the command parameters?
I've tried File.Copy but it doesn't appear to work (File.Exists("<mappeddriveletter>:\\folder\\file.txt");) brings up false.

这篇 SO 帖子包含一个
运行命令提示符命令
如何正确执行 的示例。您需要使用
/c copy作为参数来调用cmd.exe。This SO post contains an example
Run Command Prompt Commands
how to do it right. You need to call
cmd.exewith/c copyas a parameter.好吧，从技术角度来说：
copy本身不是可执行文件，而仅仅是由cmd解释的命令。因此基本上，您必须将 cmd.exe 作为进程启动，并向其传递一个标志，使其运行复制命令（您还必须供应作为参数）。无论如何，我会站在 Promit 一边，并建议研究
File.Copy或类似的东西。e：啊，当我发布这篇文章时，错过了你对 Promit 答案的评论。
Well, for the technical bit:
copyin itself is not an executable, but merely a command interpreted bycmd. So basically, you'd have to startcmd.exeas a process, and pass it a flag that makes it run thecopycommand (which you'll also have to supply as a parameter).Anyways, I'd side with Promit and recommend looking into
File.Copyor something similar.e: Ah, missed your comment on Promit's answer when I posted this.
使用 文件不是更容易吗？复制？
Wouldn't it be a lot easier to use File.Copy ?
