磁盘空间还剩吗？ [英] disk space remaining?
问题描述
.net中没有办法为给定的驱动器留下磁盘空间吗？我不能相信它，但似乎是这样。如果有人知道如何在.net库中做到这一点，我会非常感激。
谢谢，LT。

您可以使用管理命名空间类（和WMI）。
这里有一个小样本：
使用系统;
使用System.Management;
class Tester {
public static void Main（）{
Int64 i = GetFreeSpace（" C："）;
Console.WriteLine（i）;
}
public static Int64 GetFreeSpace（string logicalDrive）
{
Int64 nRet = 0;
//创建查询
String strSQL =" SELECT FreeSpace FROM Win32_LogicalDisk WHERE DeviceID =''" + logicalDrive +"''" ;
尝试
{
SelectQuery query = new SelectQuery（strSQL）;
ManagementObjectSearcher searcher = new ManagementObjectSearcher（查询）;
foreach（searcher.Get（）中的ManagementBaseObject驱动器）
{
UInt64 u =（UInt64）驱动器["自由空间"]; //获取自由空间属性
nRet =（Int64）u;
}
}
catch（例外e）
{
Console.WriteLine（e.ToString（））;
}
返回nRet / 1024; //返回KB
} // GetFreeSpace
}
Willy。
谢谢威利。我尝试了类似的东西，它似乎没有工作。
我希望.net库中有一些东西允许直接的
函数调用和不是System.Management类。对于这一点我仍然处于震惊状态，并且不能相信你不能做像
System.IO这样的事情。 DirectoryInfo.GetFreeSpace"或类似的东西...
谢谢威利。显然我必须继续使用系统管理
课程。

控制台。 WriteLine（e.ToString（））;

返回nRet / 1024; //返回KB

Willy。
DirectoryInfo没有GetFreeSpace方法，因为它设计为
常规目录（
将FreeSpace引用到常规目录是没有意义的。
System.Management类提供了一种检索信息的方式
来自WMI，
WMI的功能是纪念碑和强大的，所以我认为没有必要使用
Net来创建一个新类或
方法。（如果.Net真的创建了一个新类，它将与
WMI引擎盖互通）
如果你仍然这样做不想使用System.Management类，你可以将
引用到FileSystemObject，如下所示：
添加Microsoft Scripting RunTIme 1.0来自添加参考命令，
" COM"标签页，
Scripting.FileSystemObject FSO = new Scripting.FileSystemObjectClass（）;
string [] logDrives = System.IO.Directory.GetLogicalDrives（）;
for（int i = 0; i< logDrives.GetUpperBound（0）+1; i ++）
{
string disk = logDrives [ i] .Substring（0,2）;
string param =" Win32_LogicalDisk =''" + disk +"''" ;;
Scripting.Drive thisdrive = FSO.GetDrive（logDrives [i]）;
if（thisdrive.DriveType == Scripting.DriveTypeConst.Fix ed）
{
MessageBox.Show（thisdrive.Path +" FreeSpace：" + thisdrive.FreeSpace）;
}
}
希望这会有所帮助，
祝你好运，

Is there no way in .net to get disk space remaining for a given drive??? I
can''t believe it and yet is seems to be so. If someone knows of a way to do
this in the .net libraries I''d be very much appreciative.
Thanks, LT.

You could use the Management namespace classes (and WMI).
Here''s a small sample:
using System;
using System.Management;
class Tester {
public static void Main() {
Int64 i = GetFreeSpace("C:");
Console.WriteLine(i);
}
public static Int64 GetFreeSpace(string logicalDrive )
{
Int64 nRet = 0;
// Create a query
String strSQL = "SELECT FreeSpace FROM Win32_LogicalDisk WHERE DeviceID=''" + logicalDrive + "''" ;
try
{
SelectQuery query = new SelectQuery(strSQL);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
foreach(ManagementBaseObject drive in searcher.Get())
{
UInt64 u = (UInt64)drive["FreeSpace"]; // Get freespace property
nRet = (Int64)u;
}
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
}
return nRet/1024; // return KB
} // GetFreeSpace
}
Willy.
Thanks Willy. I tried something similar to this and it didn''t seem to work.
I was hoping there was something in the .net libraries that allowed a direct
function call and not the System.Management class. I''m still in a state of
shock regarding this and just can''t believe you can''t just do something like
"System.IO.DirectoryInfo.GetFreeSpace" or something similar...
Thanks Willy. Apparently I have to keep playing with the System Management
class though.

Hi,
DirectoryInfo does not have GetFreeSpace method, because it is design for
regular directory(
It makes no sense referring FreeSpace for regular directory).
The System.Management class provided a way of retreiving the information
from WMI, the
WMI''s function is monument and strong, so I think there is no need for the
Net to create a new class or
method for this.(If .Net really create a new class, it will interop with
WMI under hood)
If you still do not want to use the System.Management class, you can refer
to the FileSystemObject, like this:
Add the "Microsoft Scripting RunTIme 1.0" from the "Add Reference" command,
"COM" tab page,
Scripting.FileSystemObject FSO = new Scripting.FileSystemObjectClass();
string [] logDrives=System.IO.Directory.GetLogicalDrives();
for ( int i =0;i< logDrives.GetUpperBound(0)+1;i++)
{
string disk=logDrives[i].Substring(0,2);
string param="Win32_LogicalDisk=''"+disk+"''";
Scripting.Drive thisdrive=FSO.GetDrive(logDrives[i]);
if (thisdrive.DriveType==Scripting.DriveTypeConst.Fix ed )
{
MessageBox.Show(thisdrive.Path+" FreeSpace:"+thisdrive.FreeSpace );
}
}
Hope this helps,
