做的c#資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。比如怎樣把系統(tǒng)定義的
枚舉轉(zhuǎn)化成自己想要的枚舉類型。怎樣展開節(jié)點，怎樣判斷一個文件是不是隱藏文件等等一些很
小的細節(jié)需要自己慢慢去積累去學習。下面是個例子幫助自己學習和理解這些小知識。
//遍歷所有的磁盤
foreach (string log in Directory.GetLogicalDrives())
{
//得到磁盤符的類型
DriveInfo dif = new DriveInfo(log);
if (dif.DriveType == DriveType.CDRom)//如果為驅(qū)動器的設置樹形節(jié)點的
圖標
{
treeView1.Nodes.Add(log, log, 3, 3);
}
else
{
TreeNode tn = treeView1.Nodes.Add(log, log, 2, 2);//設置如果不是
驅(qū)動器的樹形節(jié)點的圖標
foreach (string logs in Directory.GetDirectories(log))
{
DirectoryInfo difs = new DirectoryInfo(logs);
if (!difs.Attributes.ToString().Contains("Hidden"))//判斷如
果不是隱藏文件
{
tn.Nodes.Add(logs, Path.GetFileName(logs), 0, 1);
}
}
}
}
foreach (string view in Enum.GetNames(typeof(ViewCN)))
{
toolStripSplitButton3.DropDownItems.Add(view).Click += ViewClick;//
遍歷所有的枚舉類型把他轉(zhuǎn)化成我們自定義的類型
}
void ViewClick(object sender, EventArgs e)
{
listView1.View = (View)(int)((ViewCN)Enum.Parse(typeof(ViewCN),
((ToolStripMenuItem)sender).Text));//把所有的枚舉類型把他轉(zhuǎn)化成自定義的類型
}
//自定義與系統(tǒng)給定的一致的枚舉類型
