我有以下方法，用于从c#运行命令提示符命令

在第一个参数中传递要运行的命令

public static string RunCommand(string arguments, bool readOutput)
{
    var output = string.Empty;
    try
    {
        var startInfo = new ProcessStartInfo
        {
            Verb = "runas",
            FileName = "cmd.exe",
            Arguments = "/C "+arguments,
            WindowStyle = ProcessWindowStyle.Hidden,
            UseShellExecute = false,
            CreateNoWindow = true,
            RedirectStandardOutput = true,
            RedirectStandardError = false
        };

        var proc = Process.Start(startInfo);

        if (readOutput)
        {
            output = proc.StandardOutput.ReadToEnd(); 
        }

        proc.WaitForExit(60000);

        return output;
    }
    catch (Exception)
    {
        return output;
    }
}

var proc1 = new ProcessStartInfo();
string anyCommand; 
proc1.UseShellExecute = true;

proc1.WorkingDirectory = @"C:\Windows\System32";

proc1.FileName = @"C:\Windows\System32\cmd.exe";
proc1.Verb = "runas";
proc1.Arguments = "/c "+anyCommand;
proc1.WindowStyle = ProcessWindowStyle.Hidden;
Process.Start(proc1);

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.

虽然从技术上讲，这并没有直接回答提出的问题，但它确实回答了如何做原始海报想做的事情:合并文件。如果有的话，这篇文章是为了帮助新手理解Instance Hunter和Konstantin在说什么。

这是我用来组合文件(在本例中是jpg和zip)的方法。注意，我创建了一个缓冲区，填充zip文件的内容(以小块的形式，而不是在一个大的读取操作中)，然后缓冲区被写入jpg文件的后面，直到到达zip文件的末尾:

private void CombineFiles(string jpgFileName, string zipFileName)
{
    using (Stream original = new FileStream(jpgFileName, FileMode.Append))
    {
        using (Stream extra = new FileStream(zipFileName, FileMode.Open, FileAccess.Read))
        {
            var buffer = new byte[32 * 1024];

            int blockSize;
            while ((blockSize = extra.Read(buffer, 0, buffer.Length)) > 0)
            {
                original.Write(buffer, 0, blockSize);
            }
        }
    }
}

如果你想保持CMD窗口打开，或者想在winform/wpf中使用它，那么就像这样使用它

    string strCmdText;
//For Testing
    strCmdText= "/K ipconfig";

 System.Diagnostics.Process.Start("CMD.exe",strCmdText);

/K

将保持cmd窗口打开吗

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
        }
    }
