.Net 2.0中的DriveInfo类
在.Net 1.1中,要获得磁盘信息,只有通过Win32的API来获得,例如:
然而在.Net2.0中,不需要做这些烦人的工作,它已经将这些Win32的API放到了Framework的类库中。在命名空间System.IO下有DriveInfo类,该类分别包括属性:TotalSize,TotalFresSpace,AvailableFreeSpace,DriveFormat,DriveType,VolumeLabel等属性。现在要获得有关磁盘的信息,就非常容易了。
另外,DriveInfo类还有一个静态方法GetDrives(),它能获得当前计算机所有驱动器的信息:
不知道.Net2.0又封装了多少.Net 1.1版本未曾实现的Win32 API呢?这还需要我们慢慢的去发掘啊。
