如何用C#启动一个进程？

例如，要启动Microsoft Word，请使用以下代码：

private void button1_Click(object sender, EventArgs e)
{
    string ProgramName = "winword.exe";
    Process.Start(ProgramName);
}

For more explanations, check out this link.

请在代码中加入 using System.Diagnostics;。

然后调用 Process.Start("粘贴你的URL字符串!");

可以尝试像下面这样：

using System.Web.UI;
using System.Web.UI.WebControls;
using System.Diagnostics;

namespace btnproce
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            string t ="Balotelli";
            Process.Start("http://google.com/search?q=" + t);
        }
    }
}

请注意，这只是一个ASP.NET页面的示例。您应该尝试并稍微改进一下。

Process openTerminal = new Process();

openTerminal.StartInfo.FileName = "/usr/bin/osascript"; // The 'osascript' command on macOS

// AppleScript to open Terminal and execute commands
openTerminal.StartInfo.Arguments = "-e 'tell application \"Terminal\" to do script \"echo Hello World\"'";
openTerminal.StartInfo.UseShellExecute = false;
openTerminal.Start(); 

你可以尝试在 macOS 上运行终端并打印 Hello world。

我认为你可以使用Win32 API中的CreateProcess。
代码示例：

using System;
using System.Runtime.InteropServices;


class Demo
{
    [StructLayout(LayoutKind.Sequential)]
    struct StartupInfo
    {
        public int cb;
        public string lpReserved;
        public string lpDesktop;
        public int lpTitle;
        public int dwX;
        public int dwY;
        public int dwXSize;
        public int dwYSize;
        public int dwXCountChars;
        public int dwYCountChars;
        public int dwFillAttribute;
        public int dwFlags;
        public int wShowWindow;
        public int cbReserved2;
        public byte lpReserved2;
        public int hStdInput;
        public int hStdOutput;
        public int hStdError;
    }

    [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    static extern bool CreateProcess(string lpApplicationName, string lpCommandLine, int lpProcessAttributes,
        int lpThreadAttributes, int bInheritHandles, int dwCreationFlags, int lpEnvironment,
        int lpCurrentDirectory, StartupInfo lpStartupInfo, out int lpProcessInformation);

    static void Main()
    {
        var info = new StartupInfo();
        if (!CreateProcess("C:\\Windows\\System32\\cmd.exe", "/c ping", 0, 0, 0, 0, 0, 0, info, out _))
        {
            Console.WriteLine(Marshal.GetLastWin32Error());
            Console.ReadKey();
        }
    }
}

参考资料：CreateProcessA函数（processthreadsapi.h）

您可以使用以下语法：

private void button1_Click(object sender, EventArgs e)  {
   System.Diagnostics.Process.Start(/*your file name goes here*/);
}

甚至包括这个：

using System;
using System.Diagnostics;
//rest of the code

private void button1_Click(object sender, EventArgs e)  {
   Process.Start(/*your file name goes here*/);
}

这两种方法都可以执行相同的任务。
