of the hard disk which is more likley D
but D is not alaways 2nd partion of the hard disk

int i;
string[] strArr = new string[16];
DriveInfo[] allDrives = DriveInfo.GetDrives();
i = 0;
foreach (DriveInfo d in allDrives)
{
    strArr[i] = d.Name;
    i++;
    // is d.Name hard disk or usb or cd etc
}

推荐答案

许多（如果不是全部）新PC都有恢复分区，它们是硬盘的第二个分区。大多数供应商会建议更改恢复分区中的数据不符合您的最佳利益。



您可以使用 System.Io.DriveType 枚举以区分驱动器类型。

以下示例选择光驱（CD或DVD）。

Many, if not all, new PCs have Recovery Partitions that are the second partition of a hard drive. Most vendors would advise that it is not in your best interest to alter data in the Recover Partition.

You can use System.Io.DriveType enumeration to differentiate drive type.
The example below selects the optical drive (CD or DVD).

string[] Drives = System.IO.Directory.GetLogicalDrives();
foreach (string strDrive in Drives) {
    System.IO.DriveInfo di = new System.IO.DriveInfo(strDrive.Substring(0, 1).ToUpper());
    // Optical Drive (CD or DVD)
    if (di.DriveType == System.IO.DriveType.CDRom) {
        strDVD = strDrive.Substring(0, 2);
        // example: F:
    }
}

可以使用以下内容找到硬盘：

A hard disk would be found using:

if (di.DriveType == System.IO.DriveType.Fixed) {

string[] strArr = new string[16];
DriveInfo[] allDrives = DriveInfo.GetDrives();
i = 0;
foreach (DriveInfo d in allDrives)
{
    strArr[i] = d.Name;
    i++;
    MessageBox.Show("Type of Drive is "+d.Drive.Type.ToString());
}
