C#实现进程管理的启动和停止实例

本文实例讲述了c#实现进程管理的启动和停止方法。分享给大家供大家参考。具体实现方法如下：

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.text;
using system.windows.forms;
using system.io;
//引用命名空间
using system.diagnostics;
using system.threading;
namespace startstopprocess
{
  public partial class form1 : form
  {
    int fileindex;
    string filename = "notepad.exe";
    process process1 = new process();
    public form1()
    {
      initializecomponent();
      //以详细列表方式显示
      listview1.view = view.details;
      //参数含义：列名称，宽度（像素），水平对齐方式
      listview1.columns.add("进程id", 70, horizontalalignment.left);
      listview1.columns.add("进程名称", 70, horizontalalignment.left);
      listview1.columns.add("占用内存", 70, horizontalalignment.left);
      listview1.columns.add("启动时间", 70, horizontalalignment.left);
      listview1.columns.add("文件名", 280, horizontalalignment.left);
    }
    private void buttonstart_click(object sender, eventargs e)
    {
      string argument = application.startuppath + "\\myfile" + fileindex + ".txt";
      if (file.exists(argument)==false)
      {
        file.createtext(argument);
      }
      //设置要启动的应用程序名称及参数
      processstartinfo ps = new processstartinfo(filename, argument);
      ps.windowstyle = processwindowstyle.normal;
      fileindex++;
      process p = new process();
      p.startinfo = ps;
      p.start();
      //等待启动完成，否则获取进程信息可能会失败
      p.waitforinputidle();
      refreshlistview();
    }
    private void buttonstop_click(object sender, eventargs e)
    {
      this.cursor = cursors.waitcursor;
      //创建新的process组件的数组,并将它们与指定的进程名称（notepad）的所有进程资源相关联.
      process[] myprocesses;
      myprocesses = process.getprocessesbyname(path.getfilenamewithoutextension(filename));
      foreach (process p in myprocesses)
      {
        //通过向进程主窗口发送关闭消息达到关闭进程的目的
        p.closemainwindow();
        //等待1000毫秒
        thread.sleep(1000);
        //释放与此组件关联的所有资源
        p.close();
      }
      fileindex = 0;
      refreshlistview();
      this.cursor = cursors.default;
    }
    private void refreshlistview()
    {
      listview1.items.clear();
      //创建process类型的数组,并将它们与系统内所有进程相关联
      process[] processes;
      processes = process.getprocessesbyname(path.getfilenamewithoutextension(filename));
      foreach (process p in processes)
      {
        //将每个进程的进程名称、占用的物理内存以及进程开始时间加入listview中
        listviewitem item = new listviewitem(
          new string[]{
            p.id.tostring(),
            p.processname,
            string.format("{0} kb", p.privatememorysize64/1024.0f),
            string.format("{0}",p.starttime),
            p.mainmodule.filename
          });
        listview1.items.add(item);
      }
    }
    private void buttonrefresh_click(object sender, eventargs e)
    {
      refreshlistview();
    }
    private void form1_load(object sender, eventargs e)
    {

    }
  }
}
