有没有办法在c#应用程序中运行命令提示符命令?如果是这样,我该如何做以下几点:
copy /b Image1.jpg + Archive.rar Image2.jpg
这基本上是在JPG图像中嵌入一个RAR文件。我只是想知道在c#中是否有一种方法可以自动做到这一点。

这也可以通过P/调用C标准库的系统函数来实现。
using System.Runtime.InteropServices;
[DllImport("msvcrt.dll")]
public static extern int system(string format);
system("copy Test.txt Test2.txt");
输出:
1 file(s) copied.
其他回答
尝试RameshVel的解决方案,但我无法在我的控制台应用程序中传递参数。如果有人遇到同样的问题,这里有一个解决方案:
using System.Diagnostics;
Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.UseShellExecute = false;
cmd.Start();
cmd.StandardInput.WriteLine("echo Oscar");
cmd.StandardInput.Flush();
cmd.StandardInput.Close();
cmd.WaitForExit();
Console.WriteLine(cmd.StandardOutput.ReadToEnd());
是的,有(参见Matt Hamilton的评论中的链接),但是使用。net的IO类会更简单更好。您可以使用File。ReadAllBytes读取文件,然后是File。写“嵌入式”版本。
这里是一个小简单和较少的代码版本。它也会隐藏控制台窗口
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
process.StartInfo.FileName = "cmd.exe";
process.StartInfo.Arguments = "/C copy /b Image1.jpg + Archive.rar Image2.jpg";
process.Start();
出于某种原因,上面的答案都没有帮助,似乎他们把错误扫到地毯下,使故障排除变得困难。所以我最终选择了这样的东西,也许它会帮助到其他人:
var proc = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = @"C:\Program Files\Microsoft Visual Studio 14.0\Common7\IDE\tf.exe",
Arguments = "checkout AndroidManifest.xml",
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = true,
WorkingDirectory = @"C:\MyAndroidApp\"
}
};
proc.Start();
如果您想在异步模式下运行该命令-并打印结果。你可以学习这门课:
public static class ExecuteCmd
{
/// <summary>
/// Executes a shell command synchronously.
/// </summary>
/// <param name="command">string command</param>
/// <returns>string, as output of the command.</returns>
public static void ExecuteCommandSync(object command)
{
try
{
// create the ProcessStartInfo using "cmd" as the program to be run, and "/c " as the parameters.
// Incidentally, /c tells cmd that we want it to execute the command that follows, and then exit.
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
Console.WriteLine("ExecuteCommandSync failed" + objException.Message);
}
}
/// <summary>
/// Execute the command Asynchronously.
/// </summary>
/// <param name="command">string command.</param>
public static void ExecuteCommandAsync(string command)
{
try
{
//Asynchronously start the Thread to process the Execute command request.
Thread objThread = new Thread(new ParameterizedThreadStart(ExecuteCommandSync));
//Make the thread as background thread.
objThread.IsBackground = true;
//Set the Priority of the thread.
objThread.Priority = ThreadPriority.AboveNormal;
//Start the thread.
objThread.Start(command);
}
catch (ThreadStartException )
{
// Log the exception
}
catch (ThreadAbortException )
{
// Log the exception
}
catch (Exception )
{
// Log the exception
}
}
}
