c#进程控制问题

Question

 private void button1_Click(object sender, EventArgs e)
        {
            Process[] p = Process.GetProcessesByName("War3");
            p[0].Kill();
        }其他的进程都可以关闭，魔兽3的进程失败，求大大解释！

Answer 1

用这个方法关闭，100%成功，你的那个是要进程正常退出，因此失败。        [Flags]
        public enum ProcessAccessFlags : uint
        {
            All = 0x001F0FFF,
            Terminate = 0x00000001,
            CreateThread = 0x00000002,
            VMOperation = 0x00000008,
            VMRead = 0x00000010,
            VMWrite = 0x00000020,
            DupHandle = 0x00000040,
            SetInformation = 0x00000200,
            QueryInformation = 0x00000400,
            Synchronize = 0x00100000
        }        [DllImport("kernel32.dll")]
        static extern IntPtr OpenProcess(ProcessAccessFlags dwDesiredAccess, [MarshalAs(UnmanagedType.Bool)] bool bInheritHandle, uint dwProcessId);        [DllImport("kernel32.dll", SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool TerminateProcess(IntPtr hProcess, uint uExitCode);        [DllImport("kernel32.dll", SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool GetExitCodeProcess(IntPtr hProcess, out uint lpExitCode);        private void KillProcess(string processId,string processName)
        {
            IntPtr killer;
            try
            {
                killer = OpenProcess(ProcessAccessFlags.All, false, uint.Parse(processId));
                MessageBox.Show(killer.ToString());
                uint exitcode = 0;
                bool ret = GetExitCodeProcess(killer, out exitcode);
                ret = TerminateProcess(killer, exitcode);
                if (ret)
                    MessageBox.Show(string.Format("成功关闭程序{0}。", processName));
                else
                {
                    exitcode = 0;
                    MessageBox.Show(string.Format("杀死进程{0}时失败，原因不明。", processName));
                }
            }
            catch (Exception Exc)
            {
                MessageBox.Show(string.Format("杀死进程{0}时失败，原因是{1}。", processName, Exc.Message));
            }
        }

Answer 2

原来如此，高手多谢，另外想问下楼主方法的原理，看不太明白，只会调用，另外这个processId怎么获取，比如魔兽3 的processId。

Answer 3

Process.GetProcessesByName("War3")返回的这个Process对象里，有个ID属性，就是processId了。

Answer 4

程序调试好了，魔兽3 的进程关不掉， MessageBox.Show(string.Format("杀死进程{0}时失败，原因不明。", processName));

Answer 5

代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;namespace exe_controller
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            PKill pkill = new PKill();
            Process[] ps = Process.GetProcesses();
            foreach (Process item in ps)
            {
                if (item.ProcessName == "War3")
                {
                    int i;
                    i = item.Id;
                    pkill.KillProcess(i.ToString(), "War3");
                }
            }
        }
    }
}
