System.Environment.GetFolderPath函數可以通過Environment.SpecialFolder枚舉參數擷取系統特定的目錄，比如案頭，我的文件，收藏夾等..但是有部分參數.NetFrameWork2.0並未開放，比如AllUser使用者的這些特殊目錄。我們可以通過windowsApi函數SHGetFolderPath來擷取，如果你能通過Reflector看一下FrameWork代碼就明白了。
代碼如下：
using
System;
using
System.Collections.Generic;
using
System.Text;
using
System.Runtime.InteropServices;
namespace
ConsoleApplication1
...
{
class
Program
...
{
[DllImport(
"
shfolder.dll
"
, CharSet
=
CharSet.Auto)]
internal
static
extern
int
SHGetFolderPath(IntPtr hwndOwner,
int
nFolder, IntPtr hToken,
int
dwFlags, StringBuilder lpszPath);
static
void
Main(
string
[] args)
...
{
for
(
int
i
=
0
; i
<=
255
; i
++
)
...
{
StringBuilder lpszPath
=
new
StringBuilder(
260
);
SHGetFolderPath(IntPtr.Zero, i, IntPtr.Zero,
0
, lpszPath);
Console.WriteLine(i.ToString()
+
"
:
"
+
lpszPath);
}
Console.Read();
}
}
}
結果如下

具體意義可以參照Environment.SpecialFolder枚舉說明和windows基本常識來理解。
