Question

我需要在c＃中编写一个程序，它只会启动，杀死一个应该杀死并结束自身的进程\ exe。

我需要杀死的进程是另一个C＃应用程序，因此它是本地用户进程，我知道 exe 的路径。

Answer 1

结帐Process.GetProcessesByName和Process.Kill

// Get all instances of Notepad running on the local
// computer.
Process [] localByName = Process.GetProcessesByName("notepad");
foreach(Process p in localByName)
{
   p.Kill();
}

Answer 2

首先搜索要杀死的进程的所有进程，然后再搜索它。

Process[] runningProcesses = Process.GetProcesses();
foreach (Process process in runningProcesses)
{
    // now check the modules of the process
    foreach (ProcessModule module in process.Modules)
    {
        if (module.FileName.Equals("MyProcess.exe"))
        {
            process.Kill();
        }
    }
}

Answer 3

按名称杀死进程可以在C＃中轻松完成（因为其他答案已经完美展现）。但是，如果你想根据可执行文件的完整路径杀死进程，则会变得更加棘手。一种方法是使用WMI，另一种方法是使用Module32First Windows API函数。

以下示例使用后一种方法。它首先按名称选择正在运行的进程的子集，然后查询每个进程的完整可执行路径。请注意，此路径将是正在执行的映像的实际路径，这不一定是已启动的可执行文件（例如，在x64系统上，calc.exe的实际路径将为C：\ Windows \ SysWOW64 \ calc.exe，即使文件C：\ Windows \ system32 \ calc.exe已启动）。具有匹配路径的所有进程都由GetProcessesByPath返回：

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Runtime.ConstrainedExecution;
using System.Runtime.InteropServices;
using Microsoft.Win32.SafeHandles;

class Program
{
    static void Main(string[] args)
    {
        Process[] processList = GetProcessesByPath(@"C:\Program Files\MyCalculator\calc.exe");
        foreach (var process in processList)
        {
            if (!process.HasExited)
                process.Kill();
        }
    }

    static Process[] GetProcessesByPath(string path)
    {
        List<Process> result = new List<Process>();

        string processName = Path.GetFileNameWithoutExtension(path);
        foreach (var process in Process.GetProcessesByName(processName))
        {
            ToolHelpHandle hModuleSnap = NativeMethods.CreateToolhelp32Snapshot(NativeMethods.SnapshotFlags.Module, (uint)process.Id);
            if (!hModuleSnap.IsInvalid)
            {
                NativeMethods.MODULEENTRY32 me32 = new NativeMethods.MODULEENTRY32();
                me32.dwSize = (uint)System.Runtime.InteropServices.Marshal.SizeOf(me32);
                if (NativeMethods.Module32First(hModuleSnap, ref me32))
                {
                    if (me32.szExePath == path)
                    {
                        result.Add(process);
                    }
                }
                hModuleSnap.Close();

Answer 4

您可以调用Process.Kill方法

您可以使用Process.GetProcesses获取所有流程或Process.GetProcessByName或Process.GetProcessById，以便您可以启动流程来致电。

Answer 5

Process[] processes = Process.GetProcesses();
foreach (Process pr in processes){ 
  if (pr.ProcessName=="vfp")
    if (pr.MainWindowTitle.Contains("test"))
      pr.CloseMainWindow();
}`enter code here`

这里的vfp是进程名称。和测试是设置标题名称。

Answer 6

您可以使用Process Class类来实现它，但为什么要杀死另一个进程？

Answer 7

进程类有Kill（）方法

Answer 8

我想定义自己要关闭的应用程序列表，所以我根据我列出的一些示例做了这个。它简单而有效。

        string[] Process_name_list = {"chrome","notepad"};
        foreach (string Process_name in Process_name_list)
        {
            foreach (var process in Process.GetProcessesByName(Process_name))
            {                    
                process.Kill();
            }
        }
