用C#怎样获取磁盘分区剩余容量？
获取分区剩余容量可以通过DriveInfo类的TotalFreeSpace属性得到，但是，当磁盘分区的剩余容量在变化中（增加或减少）的时候，我写一段程序，大体是这样子的:这个程序，录制电脑屏幕成AVI视频格式，在录制的过程中动态的存储到硬盘上，现在我要判断硬盘分区的剩余容量小到事先设定好的一个临界值，如果达到了，就写代码停止录制。这里，怎样动态的检测硬盘分区的剩余容量？请高手指教，万分感谢！ --------------------编程问答-------------------- 关注中。。。 --------------------编程问答--------------------

static void Main(string[] args)
{
Console.WriteLine(GetFreeSpace("c:\\").ToString());
Console.ReadKey();
}
///
/// 取得磁盘剩余空间
///
/// 驱动器名 /// 剩余空间
private static ulong GetFreeSpace(string driveDirectoryName)
{
ulong freefreeBytesAvailable = 0;
DriveInfo drive = new DriveInfo(driveDirectoryName);
freefreeBytesAvailable = (ulong)drive.AvailableFreeSpace;
return freefreeBytesAvailable;
}

public static long GetHardDiskSpace(string str_HardDiskName)
{
long totalSize= new long();
str_HardDiskName=str_HardDiskName +":\\";
System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
foreach (System.IO.DriveInfo drive in drives)
{
if (drive.Name == str_HardDiskName)
{
totalSize = drive.TotalSize / (1024 * 1024 * 1024);
}
}
return totalSize;
}
/// <summary>

/// <param name="str_HardDiskName">只需输入代表驱动器的字母即可 </param>
/// <returns> </returns>
public static long GetHardDiskFreeSpace(string str_HardDiskName)
{
long freeSpace = new long();
str_HardDiskName = str_HardDiskName + ":\\";
System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
foreach (System.IO.DriveInfo drive in drives)
{
if (drive.Name == str_HardDiskName)
{
freeSpace = drive.TotalFreeSpace / (1024 * 1024 * 1024);
}
}
return freeSpace;
}
private void GetInfo_Click(object sender, EventArgs e)
{
txtTotal.Text = GetHardDiskSpace("D").ToString();
txtFreeSpace.Text = GetHardDiskFreeSpace("D").ToString();
int a, b, c;
a = Convert.ToInt32(txtTotal.Text);
b = Convert.ToInt32(txtFreeSpace.Text);
c = a - b;
txtUse.Text=c.ToString();
}
每次存储的时候调用DriveInfo来检查。
补充：.NET技术 , C#
