Running cmd commands via .NET?
提问by unrelativity
System.Diagnostics.Process proc0 = new System.Diagnostics.Process();
proc0.StartInfo.FileName = "cmd";
proc0.StartInfo.WorkingDirectory = Path.Combine(curpath, "snd");
proc0.StartInfo.Arguments = omgwut;
And now for some background...
现在是一些背景...
string curpath = System.IO.Path.GetDirectoryName(Application.ExecutablePath);
omgwut is something like this:
omgwut 是这样的：
copy /b a.wav + b.wav + ... + y.wav + z.wav output.wav
复制/b a.wav + b.wav + ... + y.wav + z.wav output.wav
And nothing happens at all. So obviously something's wrong. I also tried "copy" as the executable, but that doesn't work.
什么也没有发生。所以很明显有问题。我也试过“复制”作为可执行文件，但这不起作用。

Try the prefixing your arguments to cmd with /C, effectively saying cmd /C copy /b t.wav ...
尝试将您的参数添加到 cmd 的前缀/C，有效地说cmd /C copy /b t.wav ...
According to cmd.exe /?using
根据cmd.exe /?使用
/C <command>
/C <command>
Carries out the command specified by string and then terminates
执行字符串指定的命令，然后终止
For your code, it might look something like
对于您的代码，它可能看起来像
// ..
proc0.StartInfo.Arguments = "/C " + omgwut;
Notes:
笔记：
- A good way to test whether your command is going to work is to actually try it from a command prompt. If you try to do
cmd.exe copy ...you'll see that the copy doesn't occur. - There are limits to the length of the arguments you can pass as arguments. From MSDN: "The maximum string length is
2,003characters in .NET Framework applications and488characters in .NET Compact Framework applications." - You can bypass the shelling out to command by using the
System.IOclasses to open the files and manually concatenate them.
- 测试您的命令是否有效的一个好方法是从命令提示符实际尝试它。如果您尝试这样做，
cmd.exe copy ...您会看到复制不会发生。 - 您可以作为参数传递的参数长度有限制。来自MSDN：“最大字符串长度是
2,003.NET Framework 应用程序中的488字符和 .NET Compact Framework 应用程序中的字符。” - 您可以通过使用
System.IO类打开文件并手动连接它们来绕过脱壳命令。

Daniels cmd /c idea will work. Keep in mind there is a limit to the length of a command line probably 8k in your case see thisfor details.
Daniels cmd /c 想法会起作用。请记住，是有一定限度的命令行的长度，你的情况可能是8K看到此了解详情。
Since you are in a .Net app anyway, File.Copy may be quite a bit easier/cleaner than this approach.
由于您无论如何都在 .Net 应用程序中，因此 File.Copy 可能比这种方法更容易/更干净。

Try this it might help you.. Its working with my code.
试试这个它可能会帮助你..它与我的代码一起工作。
System.Diagnostics.ProcessStartInfo procStartInfo =
new System.Diagnostics.ProcessStartInfo("cmd", "/c " + command);
// The following commands are needed to redirect the standard output.
// This means that it will be redirected to the Process.StandardOutput StreamReader.
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
// Now we create a process, assign its ProcessStartInfo and start it
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
// Get the output into a string
string result = proc.StandardOutput.ReadToEnd();
// Display the command output.
Console.WriteLine(result);
}
catch (Exception objException)
{
// Log the exception
}

Even you can try this.. this is even better.
即使你可以试试这个..这更好。
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents=false;
proc.StartInfo.FileName="iexplore";
proc.StartInfo.Arguments="http://www.microsoft.com";
proc.Start();
proc.WaitForExit();
MessageBox.Show("You have just visited " + proc.StartInfo.Arguments);
