监控高速内存卡分配单元

      事先说明一下，如果有看过第一篇的，这篇基本上可以不用看了，因为这篇95%的内容是从第一篇抠下来的，单独写这篇文章的目的是为了让这个系列的文章更完整一点，还请各位看官不要扔砖头啊。。哈哈

开工~~~~

一样的，效果图先上，要获取的信息如图所示：总的物理内存，可用物理内存，总的虚拟内存，可用虚拟内存，页面文件空间，可用页面文件空间

 

      同样的，需要一个类，命名为：MemoryInfo，类图如下：

     

MemoryInfo   
    public class MemoryInfo
    
{
        总的物理内存#region 总的物理内存
        string strTotalVisibleMemorySize = string.Empty;  //总的物理内存

        public string TotalVisibleMemorySize
        
{
            get 
{ return strTotalVisibleMemorySize; }
            set 
{ strTotalVisibleMemorySize = value; }
        }
        #endregion

        可用物理内存#region 可用物理内存
        string strFreePhysicalMemory = string.Empty;  //可用物理内存

        public string FreePhysicalMemory
        
{
            get 
{ return strFreePhysicalMemory; }
            set 
{ strFreePhysicalMemory = value; }
        }
        #endregion

        总的虚拟内存#region 总的虚拟内存
        string strTotalVirtualMemorySize = string.Empty;  //总的虚拟内存

        public string TotalVirtualMemorySize
        
{
            get 
{ return strTotalVirtualMemorySize; }
            set 
{ strTotalVirtualMemorySize = value; }
        }
        #endregion

        可用虚拟内存#region 可用虚拟内存
        string strFreeVirtualMemory = string.Empty;  //可用虚拟内存

        public string FreeVirtualMemory
        
{
            get 
{ return strFreeVirtualMemory; }
            set 
{ strFreeVirtualMemory = value; }
        }
        #endregion

        页面文件大小#region 页面文件大小
        string strSizeStoredInPagingFiles = string.Empty;  //页面文件大小

        public string SizeStoredInPagingFiles
        
{
            get 
{ return strSizeStoredInPagingFiles; }
            set 
{ strSizeStoredInPagingFiles = value; }
        }
        #endregion

        可用页面文件大小#region 可用页面文件大小
        string strFreeSpaceInPagingFiles = string.Empty;

        public string FreeSpaceInPagingFiles
        
{
            get 
{ return strFreeSpaceInPagingFiles; }
            set 
{ strFreeSpaceInPagingFiles = value; }
        }
        #endregion

        public void GetMemoryInfo()
        
{
            //实例化一个ManagementClass类，并将Win32_OperatingSystem作为参数传递进去，
            //这样就可以查询Win32_OperatingSystem这个类里面的一些信息了。
            ManagementClass mClass = new ManagementClass("Win32_OperatingSystem");

            //获取Win32_OperatingSystem这个类的所有实例
            ManagementObjectCollection moCollection = mClass.GetInstances();

            //对Win32_OperatingSystem这个类进行遍历
            foreach (ManagementObject mObject in moCollection)
            
{
                TotalVisibleMemorySize = ((ulong)mObject["TotalVisibleMemorySize"] / 1024.0 / 1024).ToString("#0.00") + "G";  //获取总的物理内存
                FreePhysicalMemory = ((ulong)mObject["FreePhysicalMemory"] / 1024.0 / 1024).ToString("#0.00") + "G";  //获取可用物理内存
                TotalVirtualMemorySize = ((ulong)mObject["TotalVirtualMemorySize"] / 1024.0 / 1024).ToString("#0.00") + "G";   //获取总的虚拟内存
                FreeVirtualMemory = ((ulong)mObject["FreeVirtualMemory"] / 1024.0 / 1024).ToString("#0.00") + "G";  //获取可用虚拟内存
                SizeStoredInPagingFiles = ((ulong)mObject["SizeStoredInPagingFiles"] / 1024.0 / 1024).ToString("#0.00") + "G";  //获取页面文件大小
                FreeSpaceInPagingFiles = ((ulong)mObject["FreeSpaceInPagingFiles"] / 1024.0 / 1024).ToString("#0.00") + "G";  //获取可用页面文件大小
            }
        }
    }  
 
      然后在HostPerformance添加一个窗体，命名为：MemoryInfoForm，代码如下：
 
     MemoryInfo Form       public partial class MemoryInfoForm : Form
    
{
        public MemoryInfoForm()
        
{
            InitializeComponent();
        }

        ComputerInfo.MemoryInfo memoryInfo = new ComputerInfo.MemoryInfo();
        private void MemoryInfoForm_Load(object sender, EventArgs e)
        
{
            memoryInfo.GetMemoryInfo();

            定义一些需要用到的项#region 定义一些需要用到的项
            ListViewItem lviTotalVisibleMemorySize = new ListViewItem(new string[] 
{ "总的物理内存", memoryInfo.TotalVisibleMemorySize });
            ListViewItem lviFreePhysicalMemory = new ListViewItem(new string[] 
{ "可用物理内存", memoryInfo.FreePhysicalMemory });
            ListViewItem lviTotalVirtualMemorySize = new ListViewItem(new string[] 
{ "总的虚拟内存", memoryInfo.TotalVirtualMemorySize });
            ListViewItem lviFreeVirtualMemory = new ListViewItem(new string[] 
{ "可用虚拟内存", memoryInfo.FreeVirtualMemory });
            ListViewItem lviSizeStoredInPagingFiles = new ListViewItem(new string[] 
{ "页面文件空间", memoryInfo.SizeStoredInPagingFiles });
            ListViewItem lviFreeSpaceInPagingFiles = new ListViewItem(new string[] 
{ "可用页面文件空间", memoryInfo.FreeSpaceInPagingFiles });
            #endregion

            将项添加到ListView控件里面#region 将项添加到ListView控件里面
            lvMemory.Items.Add(lviTotalVisibleMemorySize);
            lvMemory.Items.Add(lviFreePhysicalMemory);

            lvMemory.Items.Add(lviFreeVirtualMemory);
            lvMemory.Items.Add(lviSizeStoredInPagingFiles);
            lvMemory.Items.Add(lviFreeSpaceInPagingFiles);
            #endregion

            设置ListView的样式以及列#region 设置ListView的样式以及列
            lvMemory.View = View.Details;
            lvMemory.Columns.Add("项", 150);

            lvMemory.FullRowSelect = true;
            lvMemory.GridLines = true;
            #endregion

            timer1.Enabled = true;
        }

        private void timer1_Tick(object sender, EventArgs e)
        
{
            lvMemory.Items[1].SubItems[1].Text =memoryInfo.FreePhysicalMemory;
            lvMemory.Items[3].SubItems[1].Text = memoryInfo.FreeVirtualMemory;
            lvMemory.Items[5].SubItems[1].Text = memoryInfo.SizeStoredInPagingFiles;
        }
    }

      至此，内存信息的小程序就完成了，不过，在这过程中我发现了一个奇怪的东西，上面有获取到了一个“总的虚拟内存”这个东东，但是，我看那个数据好像不太正确，因为我系统设置的虚拟内存只有4G多，如图所示，
