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);
   }
  }
 }
}
