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。

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。

这是所有你要做的从c#运行shell命令
string strCmdText;
strCmdText= "/C copy /b Image1.jpg + Archive.rar Image2.jpg";
System.Diagnostics.Process.Start("CMD.exe",strCmdText);
编辑:
这是为了隐藏cmd窗口。
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C copy /b Image1.jpg + Archive.rar Image2.jpg";
process.StartInfo = startInfo;
process.Start();
编辑2:
参数以/C开头是很重要的,否则就行不通。正如@scott-ferguson所说:/C执行字符串指定的命令,然后终止。
你可以在一行中使用CliWrap来做到这一点:
var result = await Cli.Wrap("cmd")
.WithArguments("copy /b Image1.jpg + Archive.rar Image2.jpg")
.ExecuteBufferedAsync();
var stdOut = result.StandardOutput;
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
}
}
}
你可以使用RunProcessAsTask包,像这样轻松地异步运行你的进程:
var processResults = await ProcessEx.RunAsync("git.exe", "pull");
//get process result
foreach (var output in processResults.StandardOutput)
{
Console.WriteLine("Output line: " + output);
}
