我要评论本文讲述c#获取windows系统目录，如何目录遍历以及将信息捆绑在treeview中显示出来的实现方法，具体实现代码如下：
using system;
using system.drawing;
using system.collections;
using system.componentmodel;
using system.windows.forms;
using system.data;
using system.io;
namespace 获取系统目录
{
public class form1 : system.windows.forms.form
{
private system.windows.forms.treeview treeview1;
private system.componentmodel.icontainer components;
private system.windows.forms.button button2;
private system.windows.forms.label label2;
private system.windows.forms.button button1;
private system.windows.forms.textbox textbox1;
private system.windows.forms.label label1;
public form1()
{
initializecomponent();
filltree(treeview1, true); // 显示所有文件夹以及文件
}
protected override void dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.dispose();
}
}
base.dispose( disposing );
}
#region windows 窗体设计器生成的代码
