做的c#资源管理器所用到的一些事件和方法：一些方法需要自己去掌握。比如怎样把系统定义的
枚举转化成自己想要的枚举类型。怎样展开节点，怎样判断一个文件是不是隐藏文件等等一些很
小的细节需要自己慢慢去积累去学习。下面是个例子帮助自己学习和理解这些小知识。
//遍历所有的磁盘
foreach (string log in Directory.GetLogicalDrives())
{
//得到磁盘符的类型
DriveInfo dif = new DriveInfo(log);
if (dif.DriveType == DriveType.CDRom)//如果为驱动器的设置树形节点的
图标
{
treeView1.Nodes.Add(log, log, 3, 3);
}
else
{
TreeNode tn = treeView1.Nodes.Add(log, log, 2, 2);//设置如果不是
驱动器的树形节点的图标
foreach (string logs in Directory.GetDirectories(log))
{
DirectoryInfo difs = new DirectoryInfo(logs);
if (!difs.Attributes.ToString().Contains("Hidden"))//判断如
果不是隐藏文件
{
tn.Nodes.Add(logs, Path.GetFileName(logs), 0, 1);
}
}
}
}
foreach (string view in Enum.GetNames(typeof(ViewCN)))
{
toolStripSplitButton3.DropDownItems.Add(view).Click += ViewClick;//
遍历所有的枚举类型把他转化成我们自定义的类型
}
void ViewClick(object sender, EventArgs e)
{
listView1.View = (View)(int)((ViewCN)Enum.Parse(typeof(ViewCN),
((ToolStripMenuItem)sender).Text));//把所有的枚举类型把他转化成自定义的类型
}
//自定义与系统给定的一致的枚举类型
enum ViewCN
{
大图标 = 0,
详细列表 = 1,
小图标 = 2,
列表 = 3,
平铺 = 4,
}
