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);
}
}
}
}
