查找进程、启用进程、关闭进程
using ……
using ……
using System.Diagnostics;
//启用进程
void process()
{
Process p;//实例化一个Process对象
p=Process.Start(@"E:1.txt");//要开启的进程（或 要启用的程序），括号内为绝对路径
p.Kill();//结束进程

//查找进程、结束进程
void killProcess()

//遍历所有查找到的进程
for (int i = 0; i < pro.Length; i++)
{
//判断此进程是否是要查找的进程
if (pro[i].ProcessName.ToString().ToLower() == "pc_task")
{
pro[i].Kill();//结束进程
}
}
}
//启动、结束线程 http://www.cnblogs.com/zhangqs008/archive/2011/06/25/2341126.html
启动进程：
private void StartProcess()
{
try
{
if (!CheckProcessExists())
{
Process p = new Process();
p.StartInfo.FileName = System.IO.Path.Combine(Application.StartupPath, "DataTool.exe");
p.StartInfo.Arguments = "DataTool.exe";
p.StartInfo.UseShellExecute = true;
p.Start();
p.WaitForInputIdle(10000);
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Source + " " + ex.Message);
}
}
private bool CheckProcessExists()
{
Process[] processes = Process.GetProcessesByName("DataTool");
foreach (Process p in processes)
{
if (System.IO.Path.Combine(Application.StartupPath, "DataTool.exe") == p.MainModule.FileName)
return true;
}
return false;
}
结束进程：
private void KillProcessExists()
{
Process[] processes = Process.GetProcessesByName("AppStart");
foreach (Process p in processes)
{
if (System.IO.Path.Combine(Application.StartupPath, "AppStart.exe") == p.MainModule.FileName)
{
p.Kill();
p.Close();
}
}
}
有时再写的客户端软件中，使用到比如Quartz.net 等定时作业调度组件时，
往往会出现自己的应用程序已经关闭了，但是进程还未结束,这时，需要在关闭窗口时的FormClosed事件里加上下面的代码：
private void MainForm_FormClosed(object sender, FormClosedEventArgs e)
{
Process current = Process.GetCurrentProcess();
Process[] processes = Process.GetProcessesByName(current.ProcessName);
foreach (Process process in processes)
{
if (process.Id == current.Id)
{
process.Kill();
}
}
}
