这篇文章介绍了如何得到本地系统信息，通过使用System.Management和Sysetm.IO 来得到文件夹和文件信息，并且把它们显示到TreeView、ListView控件z之中。

首先可以使用ManagementObjectSearcher类来查询system.management域，来获取返回ManagementOjbectCollection，在这个对象中，包含了我们所需要的信息，包括盘，文件夹，文件，现在让我们来看一下整个源码：

System.Windows.Forms.Splitter splitter1;
private System.Windows.Forms.MainMenu mainMenu1;
private System.Windows.Forms.MenuItem menuItem1;
private System.Windows.Forms.MenuItem menuItem2;
private System.Windows.Forms.MenuItem menuItem3;
private System.Windows.Forms.MenuItem menuItem4;
private System.Windows.Forms.TreeView tvFolders;
private System.Windows.Forms.ListView lvFiles;
private System.Windows.Forms.ImageList m_imageListTreeView;
private System.ComponentModel.IContainer components;

这里是ide自动产生的

{

int imageIndex = 0;
int selectIndex = 0;

const int Removable = 2;
const int LocalDisk = 3;
const int Network = 4;
const int CD = 5;


this.Cursor = Cursors.WaitCursor;

tvFolders.Nodes.Clear();//清空树
nodeTreeNode = new TreeNode("My Computer",0,0);//
tvFolders.Nodes.Add(nodeTreeNode);


TreeNodeCollection nodeCollection = nodeTreeNode.Nodes;

ManagementObjectCollection queryCollection = getDrives();
foreach ( ManagementObject mo in queryCollection)
{

switch (int.Parse( mo["DriveType"].ToString()))
{
case Removable: //可移动盘
imageIndex = 5;
selectIndex = 5;
break;
case LocalDisk: //本地磁盘
imageIndex = 6;
selectIndex = 6;
break;
case CD: //光盘
imageIndex = 7;
selectIndex = 7;
break;
case Network: //网络驱动盘
imageIndex = 8;
selectIndex = 8;
break;
default: ／／默认
imageIndex = 2;
selectIndex = 3;
break;
}
//建立驱动盘的节点
nodeTreeNode = new TreeNode(mo["Name"].ToString() + "\\" ,imageIndex,selectIndex);

nodeCollection.Add(nodeTreeNode);

}
