C#进程监控方法实例分析

本文实例讲述了c#进程监控方法。分享给大家供大家参考。具体如下：

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.text;
using system.windows.forms;
using system.diagnostics;
namespace processmonitor
{
 public partial class form1 : form
 {
  process[] myprocess;
  public form1()
  {
   initializecomponent();
   datagridview1.allowusertoaddrows = false;
   datagridview1.autoresizecolumns();
   datagridview1.autosizecolumnsmode = datagridviewautosizecolumnsmode.allcells;
   datagridview1.multiselect = false;
  }
  private void form1_load(object sender, eventargs e)
  {
   getallprocess();
  }
  private void getallprocess()
  {
   datagridview1.rows.clear();
   myprocess = process.getprocesses();
   foreach (process p in myprocess)
   {
    int newrowindex = datagridview1.rows.add();
    datagridviewrow row = datagridview1.rows[newrowindex];
    row.cells[0].value = p.id;
    row.cells[1].value = p.processname;
    row.cells[2].value = string.format("{0:###,##0.00}mb", p.workingset64 / 1024.0f / 1024.0f);
    //有些进程无法获取启动时间和文件名信息，所以要用try/catch
    try
    {
     row.cells[3].value = string.format("{0}", p.starttime);
     row.cells[4].value = p.mainmodule.filename;
    }
    catch
    {
     row.cells[3].value = "";
     row.cells[4].value = "";
    }
   }
  }
  private void showprocessinfo(process p)
  {
   stringbuilder sb = new stringbuilder();
   sb.appendline("进程名称：" + p.processname + "， id：" + p.id);
   try
   {
    sb.appendline("进程优先级：" + p.basepriority + "（优先级类别： " + p.priorityclass + "）");
    processmodule m = p.mainmodule;
    sb.appendline("文件名：" + m.filename);
    sb.appendline("版本：" + m.fileversioninfo.fileversion);
    sb.appendline("描述：" + m.fileversioninfo.filedescription);
    sb.appendline("语言：" + m.fileversioninfo.language);
    sb.appendline("------------------------");
    if (p.modules != null)
    {
     processmodulecollection pmc = p.modules;
     sb.appendline("调用的模块(.dll)：");
     for (int i = 1; i < pmc.count; i++)
     {
      sb.appendline(
       "模块名：" + pmc[i].modulename + "\t" +
       "版本：" + pmc[i].fileversioninfo.fileversion + "\t" +
       "描述：" + pmc[i].fileversioninfo.filedescription);
     }
    }
   }
   catch
   {
    sb.appendline("其他信息：无法获取");
   }
   this.richtextbox1.text = sb.tostring();
  }
  private void buttonrefresh_click(object sender, eventargs e)
  {
   getallprocess();
  }
  private void datagridview1_mouseclick(object sender, mouseeventargs e)
  {
   //datagridview.hittestinfo h = datagridview1.hittest(e.x, e.y);
   //if (h.type== datagridviewhittesttype.cell || h.type == datagridviewhittesttype.rowheader)
   //{
   // datagridview1.rows[h.rowindex].selected = true;
   // int processeid = (int)datagridview1.currentrow.cells[0].value;
   // showprocessinfo(process.getprocessbyid(processeid));
   //}
  }
  private void datagridview1_cellclick(object sender, datagridviewcelleventargs e)
  {
   try
   {
    if (e.rowindex >= 0)
    {
     int processid = (int)datagridview1.rows[e.rowindex].cells[0].value;
     showprocessinfo(process.getprocessbyid(processid));
    }
   }
   catch(exception ex)
   {
    messagebox.show("发生异常,原因是：" + ex.message);
   }
  }
 }
}

希望本文所述对大家的c#程序设计有所帮助。
