求获得硬盘盘符的方法(带源码)谢绝递归

Question

转:
您可以通过查询WMI对象来获取驱动器类型。下面是一段例子代码： SelectQuery query=new SelectQuery("Select * From Win32_LogicalDisk");
ManagementObjectSearcher searcher=new ManagementObjectSearcher(query); foreach(ManagementBaseObject disk in searcher.Get())
{
this.textBox1.Text+="\r\n"+disk["Name"]+" "+disk["DriveType"];
}这段代码在我的计算机上的执行结果如下：C: 3
D: 5
E: 2
Q: 4
R: 4
S: 4
T: 4
U: 4
V: 4
W: 4
X: 4
Y: 4其中各个数字代表的意义如下：1 No type 
2 Floppy disk 
3 Hard disk 
4 Removable drive or network drive 
5 CD-ROM 
6 RAM disk 这样就可以得知各个驱动器的类型，例如C:是本地硬盘，D:是CD-ROM（实际上是一个DVD/CD-R Combo），而从Q:往后都是网络硬盘。

Answer 1

我的意思是要获得我的电脑目录下的东西
比如
我的电脑-
        +- C:        +- D:就像我get C:\下的子目录是一样的效果

一个例子不知能不能满足你的需要<%@Page Language="C#" Debug=true EnableViewState = false %>
<%@Import Namespace="System"%>
<%@Import Namespace="System.IO"%>
<%@Import Namespace="System.Data"%>
<link href="fyz.css" rel="stylesheet" type="text/css">
<script runat=server>
string[] LocalDrivers;
void Page_Load(object sender,EventArgs e){
LocalDrivers=Directory.GetLogicalDrives();
Response.Write("<b>There are "+ LocalDrivers.Length +" drivers.</b><br>");
DataSet ds=new DataSet("Dirvers");
DataTable dt=new DataTable();
dt.Columns.Add(new DataColumn("Drivers",typeof(string)));
DataRow dr;
foreach(string driver in LocalDrivers){
dr=dt.NewRow();
dr[0]=driver;
dt.Rows.Add(dr);
}
//DataSet.Tables.Add(dt);
Drivers.DataSource=new DataView(dt);
Drivers.DataBind();
}
</script>
<form runat="server">
<asp:DataList id=Drivers runat="server" Class="txt" BorderColor="#668899"
GridLines="None" Width="100"
HorizontalAlign="Center">
<ItemTemplate >
      <asp:HyperLink Text='<%# DataBinder.Eval(Container.DataItem, "Drivers")%>'
NavigateUrl='<%#string.Format("Files.aspx?path={0}",Server.UrlEncode((string)DataBinder.Eval(Container.DataItem, "Drivers")))%>'
 Target="file" runat="server" />
</ItemTemplate>
</asp:DataList>
</form>
