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);
  }
 }
}
}
