If proc.StartInfo.UseShellExecute is false, then you are launching the process and can use:

如果 proc.StartInfo.UseShellExecute 为false，则您正在启动该进程并可以使用：

proc.StartInfo.CreateNoWindow = true;

If proc.StartInfo.UseShellExecute is true, then the OS is launching the process and you have to provide a "hint" to the process via:

如果 proc.StartInfo.UseShellExecute 为true，则操作系统正在启动该进程，您必须通过以下方式向该进程提供“提示”：

proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

However the called application may ignore this latter request.

然而，被调用的应用程序可能会忽略后一个请求。

If using UseShellExecute = false, you might want to consider redirecting standard output/error, to capture any logging produced:

如果使用 UseShellExecute = false，您可能需要考虑重定向标准输出/错误，以捕获生成的任何日志记录：

proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardOutput = true;
proc.OutputDataReceived += new DataReceivedEventHandler(ProcessOutputHandler);
proc.StartInfo.RedirectStandardError = true;
proc.ErrorDataReceived += new DataReceivedEventHandler(ProcessOutputHandler);

And have a function like

并具有类似的功能

private void ProcessOutputHandler(object sendingProcess, DataReceivedEventArgs outLine)
{
   if (!String.IsNullOrEmpty(outLine.Data)) // use the output outLine.Data somehow;
}

There's a good page covering CreateNoWindowthis on an MSDN blog.

MSDN 博客CreateNoWindow上有一个很好的页面介绍了这一点。

There is also a bug in Windows which may throw a dialog and defeat CreateNoWindowif you are passing a username/password. For details

Windows 中还有一个错误，CreateNoWindow如果您传递用户名/密码，它可能会抛出一个对话框并失败。详情

Use: process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

使用：process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

According to the Process properties, you do have a:

根据Process 属性，您确实有：

Property: CreateNoWindow
Notes: Allows you to run a command line program silently. It does not flash a console window.

属性：CreateNoWindow
注： 允许您静默运行命令行程序。它不会闪烁控制台窗口。

and:

和：

Property: WindowStyle
Notes: Use this to set windows as hidden. The author has used ProcessWindowStyle.Hiddenoften.

属性：WindowStyle
注释： 使用它可以将窗口设置为隐藏。作者ProcessWindowStyle.Hidden经常使用。

As an example!

举个例子！

static void LaunchCommandLineApp()
{
    // For the example
    const string ex1 = "C:\";
    const string ex2 = "C:\Dir";

    // Use ProcessStartInfo class
    ProcessStartInfo startInfo = new ProcessStartInfo();
    startInfo.CreateNoWindow = false;
    startInfo.UseShellExecute = false;
    startInfo.FileName = "dcm2jpg.exe";
    startInfo.WindowStyle = ProcessWindowStyle.Hidden;
    startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

    try
    {
        // Start the process with the info we specified.
        // Call WaitForExit and then the using statement will close.
        using (Process exeProcess = Process.Start(startInfo))
        {
            exeProcess.WaitForExit();
        }
    }
    catch
    {
        // Log error.
    }
}

This is what worked for me, When you redirect all of the input and output, and set the window hidden it should work

这对我有用，当您重定向所有输入和输出，并将窗口设置为隐藏时，它应该可以工作

            Process p = new Process();
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.CreateNoWindow = true;
