实现效果:
知识运用：
ManagementObjectSearcher类的Get方法 //用于调用指定的WMI查询并返回结果集合
public ManagementObjectCollection Get () //返回一个ManagementObjectCollection 包含匹配指定查询的对象
PropertyData类的Value属性 //该类表是关于WMI属性的信息
public Object Value {get; set;} //Value属性用来获取或设置属性的当前值
实现代码：
private void Form1_Load(object sender, EventArgs e)
{
InsertInfo("Win32_PhysicalMemory",ref listView1,true); //将内存信息显示在列表中
}
public void InsertInfo(string Key,ref ListView lst, bool DontInsertNull)
{
listView1.Items.Clear(); //清空ListView控件
//创建ManagementObjectSearcher对象 使用其查找参数Key的内容
ManagementObjectSearcher searcher = new ManagementObjectSearcher("Select * from "+Key);
try
{
//遍历foreach语句遍历ManagementObjectSearcher对象查找的内容
foreach (ManagementObject share in searcher.Get())
{
ListViewGroup grp; //创建一个ListViewGroup对象
try
{ //设置组标题
grp = lst.Groups.Add(share["Name"].ToString(), share["Name"].ToString());
}
catch (Exception)
{
grp = lst.Groups.Add(share.ToString(), share.ToString());
}
if (share.Properties.Count <= 0) //如果没有找到信息 消息提示
{
MessageBox.Show("No Information Avable", "No Info", MessageBoxButtons.OK,
MessageBoxIcon.Information);
return;
}
foreach (PropertyData data in share.Properties) //遍历获取到的数据
{
ListViewItem item = new ListViewItem(grp);
if (lst.Items.Count % 2 == 0)
item.BackColor = Color.Wheat;
else
item.BackColor = Color.WhiteSmoke;
item.Text = data.Name; //设置项目标题
if (data.Value != null && data.Value.ToString() != "") //判断属性名是否为空
{
switch (data.Value.GetType().ToString())
{
case "System.String[]":
string[] str = (string[])data.Value;//存储属性名
string str2 = "";
foreach (string s in str)
str2 += s + " "; //拆分记录
item.SubItems.Add(str2); //添加到ListView控件中
break;
case "System.UInt16[]":
ushort[] shr = (ushort[])data.Value;
string ustr = "";
foreach (ushort u in shr)
ustr += u + " ";
item.SubItems.Add(ustr);
break;
default:
item.SubItems.Add(data.Value.ToString()); //直接添加到ListView控件
break;
}
}
else
{
if (DontInsertNull == true)
item.SubItems.Add("没有信息");
else
continue;
}
lst.Items.Add(item);
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message,"ERROR",MessageBoxButtons.OK,MessageBoxIcon.Information);
}
}
