专业：计算机科学与技术学号：学生姓名（签名）：设计题目

1、高优先权调度算法的模拟

2、进程管理器的模拟实现

二、主要内容

1、目的：

编程模拟实现进程管理器，加深对进程、程序概念掌握. 2、进程管理器

主界面如下：

（1）源代码：

<1> Form1.cs

using System;

using System.Collections.Generic;

using ponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using System.Management;

using System.Diagnostics;

namespace WindowsApplication1

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

this.listProcesses.MultiSelect = false;

this.listProcesses.View = View.Details;

this.listProcesses.Columns.Add("pname",(int)CreateGraphics().MeasureString(

"aaaaaaaaaaaaaaaaaaaaaa",Font).Width);

this.listProcesses.Columns.Add("pID", (int)CreateGraphics().MeasureString(

"000000000000", Font).Width);

this.listProcesses.Columns.Add("username", (int)CreateGraphics().MeasureString( "aaaaaaaaaaaaaaaaaaaaa", Font).Width);

this.listProcesses.Columns.Add("priority", (int)CreateGraphics().MeasureString( "aaaaaaaaa", Font).Width);

this.listProcesses.Columns.Add("Memory usage", (int)CreateGraphics().MeasureString(

"000000000000000",Font).Width);

}

private void Form1_Load(object sender, EventArgs e)

{

RefreshList();

}

private void RefreshList()

{

Process[] processes;

processes = Process.GetProcesses();

this.listProcesses.Items.Clear();

foreach (Process instance in processes)

{

ListViewItem lvi = new ListViewItem(instance.ProcessName);

lvi.SubItems.Add(FormatProcessID(instance.Id));

lvi.SubItems.Add(GetProcessUserName(instance.Id));

lvi.SubItems.Add(instance.BasePriority.ToString());

lvi.SubItems.Add(FormatMemorySize(instance.WorkingSet64));

string strToolTip = null;

ProcessModuleCollection modules;

if (pareTo("System") != 0 || pareTo("Idle") != 0)

{

try

{

////当进程不充允枚举模块时会产生异常

modules = instance.Modules;

foreach (ProcessModule aModule in modules)

{

strToolTip += aModule.ModuleName;

strToolTip += "; ";

}

}

catch (ponentModel.Win32Exception)

{

}

}

lvi.ToolTipText = strToolTip;

this.listProcesses.Items.Add(lvi);

}

}

//格式化内存字符串

private string FormatMemorySize(long lMemorySize)

{

return String.Format("{0,8:N0} K", lMemorySize / 1000);

}

private string FormatProcessID(int id)

{

return String.Format("{0,8}",id);

}

private static string GetProcessUserName(int pID)

{

string text1 = null;

SelectQuery query1 =

new SelectQuery("Select * from Win32_Process WHERE processID=" + pID);

ManagementObjectSearcher searcher1 = new ManagementObjectSearcher(query1);
