C# 运行命令提示符命令,c#,.net,command-line,command,prompt,C#,.net,Command Line,Command,Prompt,有没有办法在C应用程序中运行命令提示符命令？如果是，我将如何执行以下操作： 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。我只是想知道是否有一种方法可以在C#中自动实现这一点。是的，有（请参见Matt Hamilton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，然后使用File.WriteAllBytes写入“嵌入式”版本。这就是您所要做的所有

有没有办法在C应用程序中运行命令提示符命令？如果是，我将如何执行以下操作：

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。我只是想知道是否有一种方法可以在C#中自动实现这一点。

是的，有（请参见Matt Hamilton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，然后使用File.WriteAllBytes写入“嵌入式”版本。

这就是您所要做的所有事情，从C运行shell命令#

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();

重要的是，参数以

/C

开头，否则它将不起作用。如何说：它“执行字符串指定的命令，然后终止。”

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要做的事情：合并文件。如果有什么的话，这是一篇帮助新手理解Instance Hunter和Konstantin在谈论什么的帖子

这是我用来组合文件的方法（在本例中是jpg和zip）。请注意，我创建了一个缓冲区，该缓冲区将填充zip文件的内容（以小块而不是一次大的读取操作），然后将缓冲区写入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);
            }
        }
    }
}

尝试了@RameshVel解决方案，但我无法在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());

这里有一个小的简单和更少的代码版本。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();

关于

由于某种原因，上述答案都没有起到作用，似乎它们掩盖了错误，使解决指挥问题变得困难。所以我最终做了这样的事情，也许它会帮助其他人：

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();

您可以在一行中完成此操作：

var result = await Cli.Wrap("cmd")
    .WithArguments("copy /b Image1.jpg + Archive.rar Image2.jpg")
    .ExecuteBufferedAsync();

var stdOut = result.StandardOutput;

您可以使用以下方法（如其他答案中所述）实现此目的：

当我尝试上面列出的方法时，我发现我的自定义命令无法使用上面一些答案的语法

我发现更复杂的命令需要用引号封装才能工作：

string strCmdText;
strCmdText = "'/C cd " + path + " && composer update && composer install -o'";
Process.Start("CMD.exe", strCmdText);

您只需使用

.bat

格式扩展名编写代码，批处理文件的代码：

c:/copy/b Image1.jpg+Archive.rar Image2.jpg

使用此c#代码：

Process.Start（“file_name.bat”）

如果要保持cmd窗口打开或在winform/wpf中使用它，请像这样使用它

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

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

如果要在异步模式下运行命令并打印结果，将保持cmd窗口打开。您可以在本课程中学习：

这也可以通过C标准库的函数来完成

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.

这可能是一个阅读，所以我很抱歉提前。这是我尝试和测试过的方法，可能有一个更简单的方法，但这是从我扔代码到墙上，看看什么卡住了

如果可以用批处理文件完成，那么可能过于复杂的解决方法是让c#编写一个.bat文件并运行它。如果需要用户输入，可以将输入放入变量中，并让c#将其写入文件。这种方法需要反复试验，因为它就像用另一个木偶控制一个木偶
